Head into the backcountry with one of the best backpacking backpacks of 2023. From budget-friendly options to ultra-comfortable picks, we’ve got you covered.
Whether you’re going on a short overnight trip or a months-long thru-hike, finding the best backpacking backpack is fundamental to success. It not only needs to hold all your necessary gear, but it should also be comfortable enough that you don’t spend the day fidgeting or thinking about your pack.
The backpacking backpack market is competitive and constantly evolving. For every body type out there, there’s a pack to comfortably carry the essentials hundreds — or thousands — of miles. Your backpack is arguably the most vital element of your backpacking loadout, and can hands down make or break a long journey. It’s important to seriously consider the type of travel you intend to do with your pack, and choose one that will accommodate your needs, intended base weight, and hiking objectives.
Our team has collectively tested hundreds of these stalwart packs for the creation of this guide, with current author and Senior Editor, Chris Carter, having put over 15 different models through grueling tests in the past year alone. He has postholed through hip-deep snow in the alpine, slogged over muggy Appalachian mountains, and plodded across the African savannah with a multitude of different backpacking backpacks to bring you the streamlined selection you see today.
An alumnus of each of the Triple Crown trails in the United States, Chris has worn nearly permanent groves in his shoulders from the perpetual weight of backpack straps. He knows what it’s like to fling your load on the ground in exhaustion at the end of the day, and is constantly sniffing out packs that minimize discomfort over the long haul. Backpacking is inevitably taxing, but a good-fitting, comfortable backpack can minimize the agony.
After loads of research and miles upon miles of rigorous testing, we found the best packs for every use and budget. Because no single pack works for everyone, we’ve broken the list into categories to help you find the perfect fit. And if you need more help deciding, be sure to check out our comparison table, buyer’s guide, and FAQ sections at the end of this article.
Editor’s Note: We refreshed this article on November 24, 2023, adding additional details about our testing practices, information about how to pack a backpack correctly, and several more photos. We also made sure our product list is up-to-date with current models, colorways, and designs.
The Osprey Aether and Ariel 55 are recently updated versions of two of Osprey’s bestselling styles. Packed with features and thoroughly well-designed, the functionality and comfort of the Aether and Ariel make them our first choices for the best backpacking packs.
Although these packs are classic-style top-loaders, a large front zippered access point allows you to get into the depths of your gear without having to fully unpack. For heavy loads, the burly materials and easy, on-the-go adjustability make the Aether and Ariel strong and reliable carriers.
We like that Osprey has combined some tried-and-true backpack design elements with clever and innovative features of its own creation. For quick access to bits of essential gear, these packs offer dual-zippered hip belt pockets, stretch-mesh water bottle pockets, and a front “shove-it” pocket.
This pack offers the ability to fine-tune the fit for a variety of different shapes and sizes, including an adjustable torso length, as well as Osprey’s Fit-on-the-Fly hipbelt and shoulder straps.
Other noteworthy features include an internal hydration bladder sleeve, dual ice axe loops, and a versatile compression system that offers additional exterior storage.
Although Osprey also makes a 65L version of the Aether and Ariel, we like the 55L version for its compact profile and slightly reduced weight. For long weekend trips, these packs will offer plenty of space for most users.
They can also handle longer trips with some thoughtful packing. Yes, the Aether and Ariel are heavier than many other packs of their size, but they are ultrareliable and feel stable and balanced on the trail. If you’re looking for a burly, reliable pack that will last for years, this may be the perfect fit.

REI has been selling backpacking gear for decades. The recently updated REI Flash 55 is extremely popular, and for good reason. This pack is lightweight, highly customizable, and quite capable of the handling rugged demands of multi-day backpacking.
The Flash 55 is a modular pack, and various features can be added or removed to increase storage or shed weight. With all the organizational features included, this pack weighs around 2 pounds, 12 ounces.
By removing all of the modular features, the user can reduce the total weight by almost half a pound. Importantly, removing these features does not affect the Flash’s suspension system or carrying comfort.
At the top entry point of the main compartment, a roll-top, dry bag-esque closure system helps keep the pack compressed and the contents dry. Thanks to this roll-top, users can also choose to leave the pack’s top lid behind if desired.
Other useful features include a front mesh pocket, hydration bladder compatibility, and an ice axe attachment loop. The newest iteration features a beefier daisy chain with multiple attachment loops for more exterior lashing options.
For a backpacking pack, the REI Flash’s 100-denier ripstop nylon body feels thin and potentially fragile. Although this pack doesn’t seem to wear or tear faster than other packs in its class, users should avoid rubbing the sides of the pack against rock and rough surfaces. On the bottom of the pack, burly 210-denier nylon offers supreme protection from the ground.
At $199, the Flash 55 is one of the best values on the backpacking market. If you’re looking for a reliable, durable pack that won’t break the bank, this could be the bag for you.
For more information, check out our full review of the REI Co-op Flash 55 (previous model).
The Gregory Katmai 55/Kalmia 50 is a comfort-first backpack with well-padded straps and belt, as well as a suspension system that adjusts to your natural movement when walking, especially under load. Flex panels and rotating shoulder straps move independently with the shoulders and waist while walking.
With its FreeFloat 360 ventilated back panel, it almost eliminates the inescapable problem of lower back sweat. Gregory even added Polygiene odor treatment to the moisture-wicking back panel, so if you do sweat through it, your pack will stay smelling fresh.
The Katmai has side and bottom access zips to the storage for quick access, which also help you see inside more of the bag. That’s a bit of a love/hate feature, but we leaned toward love. The lid has a large zippered pocket on the top and a smaller one inside for stashing valuables away from the elements.
A large, shallow, front compartment makes a good place to store meal packets, maps, or guidebooks, and is covered by a stretchy mesh pocket for a layer. Additionally, it has long-trip essentials you’d expect, such as a hydration sleeve with a hanger, trekking pole loops, and a sleeping bag compartment.
The shoulder harness and hipbelt are easy to adjust and stay in place. It has an adjustable steel alloy internal frame, ranging from 18 to 22 inches in the M/L size (15-19 inches for the S/M).
If weight isn’t your biggest concern and you’re looking to maximize comfort on the trail, the Katmai 55/Kalmia 50 could be a great addition to your arsenal.
The updated women’s The North Face Terra 55 is a comfortable, affordable pack catered toward the novice hiker breaking into longer trips, or the dedicated backpacker on a budget. The women’s model features subtle female-specific tweaks, such as ergonomic shoulder straps and torso length.
In terms of durability, the Terra 55 backpack is built to last. The outer shell is made from tough 210D nylon DWR fabric that can withstand wear and tear, while the zippers and buckles are crafted with high-quality materials that are designed to go the distance.
A few standout additions give this pack a unique flair. Firstly, the front J-zip affords swift access to inside contents, without adding unnecessary weight by opening the entire front of the pack. Small features here and there, such as the OptiFit suspension system and cozy molded hipbelt, contribute to the pack’s useability, but the singular Dyno Lift load lifters take the cake as the most impressive.
Our tester has never seen something like this on a backpack before. An adjustable locking clasp on the right shoulder strap secures one end of the load lifter, which runs through some webbing behind the frame, and attaches to the other strap. The load lifter can move freely around the frame, and is therefore self-equalizing.
No more trying to perfectly adjust the left and right lifters to be the same size — this does it for you. And, if you need the shoulder straps cinched closer to the frame, simply pull the right strap through the clasp. This ingenious design is truly a game changer for snagging a comfortable fit on the go.
At 3 pounds, 12 ounces (for a M/L), this isn’t the lightest, most streamlined pack on the market. We feel some weight could be shaved off, but the thoughtful additions do make it a wonder to haul heavy loads with.
Overall, the women’s The North Face Terra 55 backpack is an excellent female-specific option for hikers seeking a reliable, comfortable, and functional backpack for extended outdoor adventures. If you’re scoping out an approachable pack for your first big trip, or just need a well-designed budget model to add to your arsenal, this could be a solid option.
For an ultralight pack, the 2400 Southwest Pack from Hyperlite Mountain Gear strikes a rare balance between comfort, weight, and durability, making this our top pick for an ultralight setup. This pack is built almost entirely from Dyneema — a super strong and incredibly light material.
Although Hyperlite makes similar packs with larger capacities, many users prefer the 40L size of the 2400 Southwest Pack, which weighs in at a featherlight 1 pound, 14 ounces.
Most ultralight backpacks simply are not as stable or comfortable as heavier packs. The Southwest Pack manages to break the mold. Even with a full load, this pack is quite enjoyable to hike with.
A ¼-inch back panel pad adds significant cushioning that prevents the pack’s contents from poking into the user’s back. Structural support comes from removable aluminum stays, which help distribute the pack’s weight evenly across the user’s body.
Like most ultralight gear, this pack is minimalist and basic in its tube-like design. Aside from the main compartment, the pack features three exterior pockets and two zippered hipbelt pockets.
The roll-top system seals with a Velcro closure and fastens to the pack’s sides with buckles. Apart from a simple hydration bladder sleeve, there are no internal zippered pockets or organizational features.
In addition to various size options, the Southwest Pack is also available in two different Dyneema fabrics. The 50-denier version is white, while the 150-denier version is black and costs $20 more. Most users report great durability, even with the thinner version.
For the ultralight backpacker looking for a pack that will survive the rigors of a thru-hike and beyond, it doesn’t get much better than the 2400 Southwest Pack.
ULA Equipment has some big-time fans in the world of thru-hiking. The company has rightfully earned its reputation for comfort and durability the hard way — on the backs of thru-hikers over thousands of collective miles.
If this USA-made cottage brand had a flagship pack, it would probably be the Circuit. A top choice for the PCT and other thru-hikes, the Circuit falls into that versatile size of 4,200 cubic inches (68 L).
Weighing in at just 41 ounces, the Circuit can still handle loads up to 35 pounds, making this pack a go-to choice for the weekend hike with a bear bin and fishing pole, or a summer-long adventure on the Pacific Crest Trail.
For its versatility, consumers absolutely love this pack. Recommended for a base weight of 15 pounds or less (up to 35 pounds total load), the Circuit carries weight with a remarkable 1.2-ounce carbon fiber and Delrin suspension hoop in conjunction with a dense internal foam frame and a single aluminum stay.
It provides modest organization with the main body, a front mesh pocket, left and right side mesh pockets, an extension collar, and left and right hip belt pockets. ROBIC fabric provides a durable but very light foundation for this pack. If you’re considering an ultralight backpack for your next adventure, don’t look past the ULA Equipment Circuit.
Want to carry an entire base camp on your back? Well, look no further. Loaded with days of camping gear, multiple tents, a full trad climbing rack, and two ropes, we recently took the Baltoro 75 on a serious test drive in the Appalachian Mountains. As much as a pack weighing 60 pounds can float behind you … this one floated.
True to their reputation, Gregory carries on the Baltoro’s legacy with the newest iteration of this crowd-favorite beast. Super stable, cushioned to the max, with a solid suspension system, this pack bears massive loads with about as much ease as you could ask for.
The Baltoro has always distributed heavy loads evenly. The full-perimeter metal frame and compression straps offer phenomenal structure and work well with its 3D Air hip belt and shoulder straps that rotate to your body’s geometry for a dialed-in fit. This allows the pack to move with you without feeling sloppy and unbalanced. A layered, breathable back panel with multi-density foam affords stellar breathability on sweaty missions.
Often we’ll read jargon like that in a specs list and pass it off as marketing nonsense, but this system genuinely delivers as promised in a way we haven’t seen on many other packs.
This is undeniably a clunker of a 5-pound bag, with more straps, cinches, zippers, and buckles than we’d like to count, so if lightweight minimalism is what you’re after you should look elsewhere. It can get overwhelming at times, but without all the extras it wouldn’t be the workhorse it is. We have some concerns about the tall side pockets that flank the pack. When it is full these are difficult to access and make grabbing stuff on the go quite a chore.
All in all, Gregory’s flagship Baltoro remains one of the most reliable heavy-haulers on the market. If you need to carry everything imaginable without breaking your back, this could be the perfect choice.
Osprey’s Exos 58L pack has been a top lightweight pick for long-distance backpackers and weekend hikers for years, and its newest iteration doesn’t disappoint. Offering an extremely well-built, breathable design, the Exos is packed with thoughtful features, but still manages to keep the pack’s overall weight surprisingly low.
Coming in at almost half the weight of many traditional backpacking bags, and approaching the weight of some frameless, ultralight models, the Exos delivers supreme comfort in a lightweight, simple package.
The Exos uses Osprey’s AirSpeed suspension system, which keeps the pack’s weight off your back, and maximizes ventilation with an alloy frame and a tensioned, breathable-mesh back panel. The beefy, perforated shoulder straps and seamless, layered mesh hip belt contribute to the pack’s comfortable, breathable feel.
The suspension system is quite robust on the Exos, despite its minimal weight, and carries loads of up to 45 pounds pretty well. Beyond that weight, it may feel less comfortable and capable.
Some additional, helpful features of the pack include a removable lid with an integrated flap protecting gear when the lid is off, Osprey’s Stow-on-the-Go trekking pole attachment system, and ice axe attachments with bungee tie-offs. The new Exos addresses a couple of complaints users had with the older model, adding a simple torso adjustment system, and bringing back the cherished hip belt pockets.
On the hunt for an even lighter option for fast-paced ultralight missions? Osprey recently released their Exos Pro, which is nearly a pound lighter than this cult classic. Read our review of this featherweight feat of engineering in our roundup of the Best Ultralight Backpacks.
For the weight-conscious adventurer seeking a mega-light setup, without skimping on comfort or moving to a frameless model, this may just be the perfect compromise.
For the dedicated backpacker who’s looking to dip into ultralight travel, but doesn’t want to jump completely to frameless models, the Big Agnes Prospector 50L offers hikers a high-performance, comfortable backpack at a competitively light weight.
Packed with features such as a full-zip back panel to access gear inside, tear-resistant fabric, loads of pockets, and a unique, comfortable suspension system, the Prospector delivers comfort and performance that you would expect to find in some of the popular heavier options.
One of the selling points of the Prospector is its unique Hoist Compression system which pulls the pack’s weight inward and upward for a more balanced pack weight. Combined with a suspension system that integrates its cored aluminum perimeter frame, shoulder straps, and hipbelt, the pack delivers noticeable balance on uneven terrain while still hugging the weight close to your body.
This design transfers weight well into the hips. The hipbelt, while it could use a little more padding, is comfortable and well-engineered with two adjustment points to customize the fit. The hipbelt pockets are removable, which is nice if you are trying to pair down on weight, but they are consequently quite loose fitting and bounce around a little while walking.
The pack is also incredibly durable, and held up great to bushwhacks through dense underbrush, and long multiday pushes on the open trail. While not quite as ventilated as some of the other models in its weight category, the channels in the back panel regulate sweat buildup adequately and the contoured shoulder straps and generous padding on the back make for a super comfortable carry.
Perhaps our biggest gripe, however, would be how high the frame is. It carries loads well, but unless the pack is totally filled it sticks up high on the back which looks and feels somewhat awkward.
If you are looking for a durable and versatile backpack for lightweight comfort on trail, the Big Agnes Prospector 50L is a solid option for weekend warriors, and long-distance thru-hikers alike.
The streamlined and simple Deuter Aircontact Ultra delivers exceptional carrying comfort with a surprisingly lightweight and thoughtfully featured design. This pack is catered toward the thru-hiking crowd who may want a similar weight to ultralight packs, but are still looking for the comfort and support of traditional backpacking bags.
After extensively testing both the regular 50+5L and women’s-specific 45+5L SL versions, we can confidently say we would trust, and enjoy, taking this on a long journey across the country. It carries loads as comfortably and evenly as the best of them.
Tipping the scales at a relatively scant 2.6 pounds, it just sneaks in under the weight of the comparable Osprey Exos, though the weight savings make it a little less breathable. Its back panel still offers competitive ventilation. Deuter’s Aircontact back system has a suspension design that is easily adjusted to meet various torso lengths.
Two small carabiners are accessed via a Velcro flap near the brain of the pack, and can be clipped to three different loops, raising or lowering the shoulder straps. This helps to absorb jostling and contributes to a smooth ride as you bounce down the trail.
Despite its light weight, the Aircontact Ultra carries loads incredibly well, and distributes weight to the hips with an ultralight elastic spring steel frame. The shoulder straps and hip belt have adequate padding for base weights most thru-hikers would be toting, but once you start seriously loading it up we found ourselves wishing for a little more cushion. We loved the ergonomically shaped Active Fit shoulder straps, though, and felt completely comfortable with kits up to around 45 pounds.
This pack would be perfect for the long-distance hiker looking to dip into the ultralight scene without compromising on top-shelf comfort, durability, and function. The Aircontact Ultra is a lightweight, cozy ride that offers plenty of features to make a grueling, multi-month trek as pleasurable as possible.
The Granite Gear Blaze 60 is a lightweight pack that can easily carry heavy-duty loads. It’s difficult to find a pack that remains comfortable even when fully weighed down with a week’s worth of gear, but with tons of classic and innovative features and pockets, the Blaze 60 is one of the true gems of the backpack market.
At 3 pounds, this pack is slightly lighter than average for its capacity. Although it performs well across the board, the most striking characteristic of the Blaze 60 is its phenomenal suspension system.
No matter what you need to carry, this pack will handle it with stability and grace. The internal frame that enables the pack’s stability is designed with effective airflow channels that help keep your back cool. Of all the packs with breathable back panels out there, the Blaze 60 stands out.
The shoulder and hip straps are mesh-free and tend to feel a bit sweaty. This pack features durable material in high-wear zones, and it saves weight with thinner fabric in areas of less concern.
The ROBIC fabric that covers much of the pack’s body is both light and tear-resistant. For backpackers who plan to carry full and heavy loads but don’t want an ultra-bulky pack, the Blaze 60 is a top pick.
The Arc Blast 55 from Zpacks was made specifically for the ultralight backpacking crowd. At just 1 pound, 5.3 ounces, it really doesn’t get any lighter than this for a pack with 55 L of storage.
In just about every way, this is a minimalist piece of gear. Mesh-free hip and shoulder straps are simple and thinly padded, and the hip straps do not have pockets.
Few external pockets exist on the entire pack, although it does have ice axe loops and trekking pole holders. Simply put, this is not the pack to buy if you are looking for robust padding and maximum extra features.
Instead, what you get with the Arc Blast is a world-class tool for fast and light backpacking. Although it is rated to carry upward of 30 pounds, this pack really shines with sub-25-pound loads.
The five-piece carbon frame is integrated into the pack itself, and we do not recommend trying to remove it. The user can shape the frame to create a gap of airflow between your body and the back panel, and a rectangle of mesh further helps keep your back distanced from the body of the pack.
The Dyneema fabric of the Arc Blast’s body is super-lightweight, water-resistant, and abrasion-resistant. A Velcro roll-top closure keeps water out — even in gnarly storms.
Because this pack is specialized and expensive, we don’t recommend it to beginner backpackers or casual weekend hikers. Instead, this is a minimalist tool that is best suited for a light and fast thru-hiking mission or alpine traverse.
The Resistor and Capacitor backpacks from Helly Hansen share many aesthetic and functional characteristics. The smaller Resistor is an excellent compact option for quick and light trips, while the larger Capacitor can easily handle long multiday expeditions in the mountains.
While Helly Hansen is a long-established maker of high-quality alpine outerwear, the Resistor and Capacitor are relatively new additions to the brand’s lineup. Both styles have a large top-loading main compartment, hydration compatibility, and a floating top lid with zippered pockets.
At the top of the main compartment, extendable collars provide versatile options for expanding the internal capacity and protecting the contents from the elements. The updated packs are now also fitted with Recco Transponders, which reflect directional radar signals that can be detected by rescuers in the case of an emergency.
We recently took the newest Capacitor on a mountaineering trip with Helly Hansen in the North Cascades. Hauling days of food and gear for our basecamp up near vertical, washed-out trails was a comfortable cinch with this hardworking beast, and the suspension system kept us about as comfortable as one can be. Dual ice-axe loops allowed for easy transport of our alpine climbing gear. The large front zippered compartment is made of tough material, and was perfectly sized for our spiky crampons.
Both the Resistor and the Capacitor include an adjustable back panel and customizable torso length. And 3D mesh across the entire back panel helps keep your back cool and ventilated while hiking. A thickly padded hip strap also comes equipped with a breathable mesh lining.
While these nice-looking and highly capable packs aren’t especially light, they are reliable workhorses that will perform exactly as a good backpack should. If a durable, compact pack is on your wish list, the Resistor or Capacitor would be a perfect option.
In the spirit of affordable minimalism, Osprey has delivered a modest, durable, and relatively functional pack with the Rook 65. While it will get you from point A to point B, it doesn’t perform quite as well as others we’ve tested, and though it is lighter than a lot of other models in this size range, it seems to be pretty heavy given its lack of features. If basic function that’s easy on the wallet is what you are after, the Rook could be a great match.
Costing only $180, this pack’s value is really where it shines the most. While it lacks some of the comfort and technology of Osprey’s other models, it is undeniably durable, and is on the lighter end of the spectrum given its slimmed-down design.
At that price point, it could be hard to find a pack that will hold up to the wear and tear of the trail like the Rook will. Additionally, it still does offer some of the great features we have grown to love in Osprey’s other packs, such as impressive ventilation, adjustable torso sizing, and solid suspension. Compared to other models, the Rook doesn’t carry loads quite as well, but you can’t ask for too much when paying significantly less.
The comfort of this pack is what could use the most improvement. The shoulder straps, while ergonomically shaped, don’t offer quite enough padding for loads over 40 pounds, and carrying comfort seemed to diminish significantly after around 35 pounds.
For lighter loads, however, the suspension system worked well, and we felt like the hipbelt was adequately comfortable. Though it doesn’t boast all the bells and whistles of other packs, it gives you essential features such as compression straps on the side, two dual-access water bottle pockets, and hipbelt pockets.
As a durable, affordable backpack, the Rook 65 would be great for the adventurer on a budget looking for a reliable and functional workhorse for long missions in the mountains.
The Aircontact Core is Deuter’s newest premium backpacking bag, drawing from years of innovation and successful products like the older Aircontact Lite, so we were pretty stoked to take it for a whirl. Right out of the box, it looks sleek. The 500-denier textured polyamide fabric is durable and smooth, and just looks top-notch.
The Aircontact back system, pairing breathable mesh with a large ventilation channel, works well with Deuter’s Active Fit shoulder straps that allow the pack to move with you, without feeling too wobbly or unbalanced. If you fill it out entirely the pack does stick up pretty high above your head. We found ourselves wishing the load lifters were placed a little higher, as the pack became slightly unwieldy when maxed out. Not horribly, though.
We love the J-shaped zipper on the front of the pack as this still gives you duffel-style access to your gear without adding unnecessary weight by having the zipper open the entire front panel. They did, however, add a zipper inside to open the fabric that separates the sleeping bag compartment at the bottom of the pack, which we feel could be swapped with another method to reduce some weight.
This thing is undeniably comfy and maintains a relatively competitive low weight despite all the extra features and volume. It carries heavy weight well, and expands to accommodate seriously large loads. Their Vari-Slide customizable back system is a quick, well-designed solution to fine-tune the pack’s fit while on the go, and is much more simple than some of its competition. This is a cherished feature for sure.
In short, the new Aircontact Core carries the torch of Deuter’s reputation for cranking out reliable, stellar backpacks for any adventure you could find yourself in. While not the lightest pack on the market, it definitely isn’t the heaviest, and the added features contribute well to its overall useability, without adding unnecessary weight.
The GearJunkie team is made up of all sorts of backpackers. From weekend warriors to seasoned thru-hikers, we’ve collectively spent many years on the trail.
Staff writer Austin Beck-Doss has clocked countless miles under the weight of bulging backpacking backpacks. A prolific rock climber, hiker, and all-around outdoorsman, he knows the value of a cozy pack for schlepping heinous loads to the far-flung corners of the world. He led the charge with this guide, accruing our initial selection of nine packs in May 2021.
Chris Carter took over this guide in August 2022. He has significant experience putting various backpacks through torture and torment, having thru-hiked the Triple Crown of long trails in America: the Pacific Crest Trail, the Continental Divide Trail, and the Appalachian Trail. He’s navigated the sinking sadness of a mid-hike pack failure, and knows the importance of choosing a model that fits your needs, and will last the distance.
This list of product recommendations above results from thorough field testing. When testing packs, we pay careful attention to ease of use, long-term durability, comfort, and overall value. Impressive-sounding features might look good on paper, but they don’t always translate to actual performance. Our testing aims to determine a pack’s true utility.
Every year, design updates and new products roll out across the market. We make sure to keep our finger on the pulse of the backpacking world and test out any new style that has the potential to be great. This list of recommendations is always in flux — and it represents the best of the best at any given time.
Purchasing a backpacking backpack — especially for the first time — can be a challenging process to navigate. Reliable gear is the foundation of a successful backpacking trip, and a good pack may be the most important item in your whole kit.
While hiking, the ideal pack should feel balanced and comfortable. In camp, a well-designed pack helps keep your systems organized and efficient.
In this how-to-choose guide, we will go over all of the important considerations that will help you choose the right pack. Everything from padding and water protection to sizing and capacity is explained here in detail. By the end, we hope that you’ll feel confident about choosing the perfect pack to support your backpacking adventures.
When deciding which pack size is right for you, you’ll need to complete a few quick self-measurements. Because torso size can be very different even for two people of the same height, you should not choose your pack size simply because you are tall or short. Instead, you’ll want to determine your torso and waist measurements.
Torso measurement is the most important factor for pack sizing. To figure out yours, you’ll need a friend and a cloth tape measure. If you don’t have one, a length of rope or string and a measuring stick will also work.
Begin by resting your chin against your chest and have another person locate your C7 vertebra at the base of your neck (it’s the one that tends to protrude more than the others). Place your hands on your hips so that your hands are sitting on top of your hip bones and your thumbs are pressed against your lower back.
Ask your friend to measure the length between your C7 vertebra and the center point of your spine at the level of your thumbs. This distance is your torso measurement.
Your waist size is the circumference of your waist at your iliac crest, which is the highest point of your hip bones. The middle of your backpacking hip straps should be positioned directly on top of your iliac crest. While hiking, 80% of your load should be carried by the hips and lower body, so it is essential that your hip straps fit properly.
If you are unable to find a pack that fits both your torso and hip measurements, you will likely be able to find one with replaceable hip straps. Some packs are more adjustable than others, and it is certainly a good idea to try a pack and ensure that it properly fits before purchasing.
Backpacking packs come in many different sizes and capacities. When deciding the best pack capacity for you, there are several factors worth considering. For longer trips with multiple overnights, you’ll need more space to pack the appropriate kit.
In cold weather, you’ll need more space for clothing and warm sleeping gear. Food and water are also important considerations. If you need to carry several days’ worth of food and/or water, you’ll need to be sure that your pack can handle it.
The most common length of a backpacking trip is 2 to 3 days. For these short trips, a pack between 50 L and 70 L will likely provide enough capacity for most people.
On a single overnight trip, a smaller pack of around 35-40 L may be sufficient. For extended trips over 3 days long, you’ll want a larger pack that holds at least 60 L — especially in cold weather.
Contemporary backpacking packs are designed to be both lightweight and capable of carrying heavy loads. Most packs come with a recommended range of how much weight they can hold. Pack features that contribute to weight capacity include the frame, suspension system, and padding.
When these features become more robust, maximum load capacity increases. For this reason, bulkier packs tend to be best for carrying the heaviest loads. Still, many modern options, such as the ULA Circuit, stand out as impressive haulers even though their baseline weight is relatively low.
Some manufacturers provide load ratings for their packs. It is a good idea to estimate the total weight of the loads you plan to carry before purchasing a pack.
Suspension is a system of frames, hip belts, straps, load lifters, and harnesses that keep you securely connected to your pack. Overall, a pack’s suspension system transfers the weight of your gear onto the appropriate structures of the human body.
If fitted properly, a good suspension system allows the wearer to move freely and maintain a natural sense of balance while hauling the pack. Effective suspension relies on a combination of fit and design to maximize comfort and efficiency while hiking.
Different pack manufacturers utilize slightly different suspension features. Generally, your pack should be carried by the structure of your hip bones and the strength of your legs and lower body.
The remaining weight should be transferred between your chest, shoulders, and other parts of the upper body. Fitting your pack properly is all about fine-tuning the suspension system.
Because your pack will be in direct contact with your body during strenuous physical exercise, it’s important that it breathes properly. Without sufficient breathability, you are likely to sweat uncomfortably and potentially overheat while hiking with your pack.
The two primary areas of a pack that should have effective ventilation are the back panel and the hip straps. Your back panel conforms to your back, and there should not be too much negative space between the panel’s surface and your back. Some contemporary packs feature a fully suspended mesh back panel that maintains airflow along the length of the back.
Other packs simply utilize a pattern of offset mesh and foam panels to create channels of airflow across the surface of the wearer’s back. Generally, suspended mesh back panels will allow for more ventilation than the offset mesh/foam styles.
Hip straps should also be designed to allow for breathability and airflow. Excessive sweating beneath a hip strap can lead to discomfort and blisters.
Not all backpackers have the same organizational preferences. There are many ways to organize a pack, and certain styles will be better suited to certain users based on these preferences.
Traditional backpacks use what is called a top-lid closure, which usually consists of a large opening that cinches closed, covered by a brain. Rolltop bags, on the other hand, are streamlined, no-frills backpacks that close like a dry bag on top, though usually aren’t entirely waterproof.
The rolltop system, used on wildly popular packs such as Hyperlight’s 2400 Southwest, has become a super common design on ultralight models, as it makes it easy to eliminate unneeded backpack volume by rolling up the excess fabric. This is especially helpful for thru-hikers whose pack volume tends to vary significantly over the course of a 5-month excursion through different climates and environments, or even between town stops. These also help compress the pack’s contents for a less bulky, more compact load. Something thru-hikers are always after.
The main compartment of a backpack is the largest storage space. Some backpackers prefer a simple pack that doesn’t have more than a giant singular main compartment (such as many rolltop models), and others prefer packs with lots of separate pockets and pouches. Usually, the main compartment is where your bulky and heavy items will go, including a tent, sleeping bag, and clothes.
Nearly all backpacks have a large opening at the top where users can access the main compartment. Some packs, such as the Osprey Aether & Ariel 55, have additional entry points into the main compartment, allowing users to access items within the pack without removing everything on top.
Many packs include some small pockets integrated directly into the hip belt. These are convenient places to store items that you will want to access without removing your pack, like lip balm, granola bars, or a GPS device.
A pack’s top lid usually sits above the main compartment access point. Zippered top lid pockets are a good place for lightweight items that you will want to easily access, including a headlamp, rain layers, or a lightweight puffy jacket.
In most cases, you’ll need to remove your pack to access the top lid pockets, or you can always ask your hiking buddy to help you out.
Some packs come with an integrated hydration pocket. Typically, a hydration pocket is a sleeve-like space where a water bladder or hydration pouch will fit easily and stay out of the way of your other gear.
A thoughtfully designed pack will also have a simple way to secure and access a water bladder drinking tube. If you prefer to drink out of bottles while hiking, look for a pack with exterior water bottle holders for easy access.
Compression straps help compress and condense the load in your pack and keep the bulk of the pack’s weight close to your body. Without properly tightened compression straps, a pack can swing and sway while hiking, which can throw off your balance and cause discomfort or fatigue.
Each time you put on your pack, cinch the compression straps to ensure a stable and comfortable load. Smaller items can also be clipped to or stored underneath the straps for easy on-the-go access.
Compression straps really only make sense on backpacks with frames, as they serve to pull the load into the frame to hug it closer to your back. Frameless packs, like many ultralight models, may have straps on the side, but those are generally only used for lashing things to your pack, like trekking or tent poles. They can serve to snug the load in a bit to prevent it from swaying around, but they won’t provide the same advantage as straps on a fully framed pack.
When backpacking, you’ll need to be prepared to keep your kit dry in case of rain. Many backpacking packs come with a rain cover, which is usually a form-fitting piece of waterproof nylon with an elastic perimeter. The cover should fit over your entire pack and cinch securely in place.
When not in use, the rain cover can be stored in an accessible place such as the pack’s top lid pocket. Certain styles also have fully integrated rain covers that are sewn or stitched directly into the pack.
Many backpackers prefer to use a waterproof pack liner instead of (or in addition to) a rain cover, as a rain cover leaves the back of the pack open to water seeping through to the gear inside. This method works best with backpacks with only one big, main compartment.
This is the best, and cheapest, way to ensure that your gear stays completely dry. And you don’t have to waste time desperately fitting a rain cover over your pack as a freak storm sweeps in, as the inside contents are already protected.
While you can just opt to use a burly trash bag, many manufacturers have come up with more durable, backpacking-specific pack liners that are designed to last for months.
The two most popular waterproof pack liners are Nylofume bags, such as this one sold by Waymark Gear, and polyethylene bags, such as this one sold by Gossamer Gear. Both of these options are extremely durable alternatives to trash bags or rain covers, and also help serve as odor barriers when tied off securely at the top. One Nylofume liner from Waymark kept our tester’s gear bone dry for an entire 3-month thru-hike of the Appalachian Trail, a journey that wasn’t lacking in heinous storms and constant drizzle.
You usually see backpacking packs utilizing one of two types of fabric: Dyneema composite (DCF) or some form of solid ripstop nylon. The tougher the fabric, the more durable it is likely to be, but often at the cost of increased weight. Packs like the Osprey Rook boast stellar 600- and 1,000-denier nylon packcloth, and could be carried into battle.
On the other end of the spectrum, ultralight models such as the Zpacks Arc Blast use abrasion-resistant Dyneema, but need to be babied a bit more and are catered for hikers sticking to on-trail travel with minimal bush bashing. Generally, DCF is lighter and repels water better, but comes at a higher price point.
Some backpackers prefer to shed weight from their kit by just about any means necessary. Because packs are one of the heaviest items in a backpacking kit, the ultralight crowd has developed and popularized a range of super-lightweight backpacking packs.
Though it sounds great to reduce weight and feel lighter on the trail, ultralight packs certainly do come with some drawbacks. Most of these models have reduced storage space, minimal padding, and a less substantial frame. As long as you keep your base weight to a minimum, this isn’t a problem. But, if you tend to go over 15-20 pounds with your base weight, a sturdier, more supportive pack is probably the move.
Also, an ultralight pack’s general construction is thinner and less robust. This keeps weight to a minimum, but results in a significant decrease in durability. Still, for those who are all about going light and fast — and don’t plan on doing a lot of bush-whacking — ultralight packs are a viable option.
Though backpacks vary in design and construction, there are a few reliable methods of efficiently packing any backpack that will maximize comfort and load distribution on your forays into the mountains. A well-packed bag will feel a lot lighter than a poorly-packed bag. And it will help reduce stress and discomfort over the long haul.
Starting at the bottom of the pack, it’s a good idea to pack lighter, fluffier items such as a sleeping bag. This creates something of a pillow on your lumbar, on top of which the heavier items can sit.
Additionally, you probably won’t be needing your sleeping bag until the end of the day when you are setting up camp, so there is no problem with shoving it to the bottom.
On this same note, it’s helpful to put the other elements of your sleep system, such as a sleeping bag liner and sleeping pad, in the bottom of the pack. These items are also relatively lightweight and won’t be needed throughout the day.
Next, you want to pack the middle section of the bag, which will house the heaviest items in your kit. You want to pack this gear (such as your food bag, cooking system, and backpacking tent) as close to your back as possible.
By putting these items in the middle of your back, you alleviate a significant amount of stress from your shoulders or lower back. You can also use spare clothes that you probably won’t need throughout the day to fill in the gaps between these items. This will keep them from shifting around while you are hiking, and help prevent irregular items from poking you uncomfortably as you plod along.
Finally, at the top of your bag, you want to pack lighter items that you may want to use throughout the day, such as a midlayer or rain jacket. Once the main compartment is filled, you can put smaller items that you may want to easily access in the outside compartments of the pack. This could include a headlamp, first-aid kit, or maps.
While packing your bag, you want to think of what you’ll need throughout the day, how the weight is distributed, and if you can quickly protect all of your gear from sudden changes in weather.
If you use a rain cover as your primary protection, every pocket will be protected. But, if you rely on a pack liner, you need to make sure that the items in external storage are in additional waterproof containers or dry bags.

Backpacking packs vary in price and value. High-quality options range from around $200 to well over $500. More expensive packs may include higher quality materials or extra features, but sometimes simpler is better when weight is the biggest concern.
With ultralight backpacking rising in popularity, and lightweight, durable packs coming out to match the demand, the comfort-to-weight ratio is a big deciding factor for many backpackers. The Osprey Aether & Ariel 55 are loaded with features and are extremely durable.
However, many hikers would opt for the more fragile, simpler Zpacks Arc Blast 55 as a lightweight alternative for fast missions in the mountains, even though it may not last as long as the Osprey.
As you think about which pack to get, consider what you need it for, and the level of comfort you want for the trips you have in mind. Are you bushwhacking through dense underbrush for an extended weekend? Maybe a heavier, durable pack is the best option.
Are you trying to clock big miles on an established trail through the Cascades? A lighter, simpler model may be the best fit. A good pack can last for many adventurous years on the trail, so consider your pack to be an investment.
The best backpacking pack is the one that fits your body and your backpacking objectives. We’ve included lots of excellent packs on this list.
For most people, comfort is paramount. You’ll be hiking great distances with your pack on, and you don’t want to dread doing what you love because of uncomfortable gear.
Measure your torso length and waist size carefully before choosing a pack. Determine a capacity range that allows you to pack everything you’ll need on your backpacking trips. If you like certain features or have organization preferences, seek them out when it’s time to make a purchase.
The ideal size of your pack depends on your own dimensions, as well as on the amount of gear that you plan to carry. For trips up to 3 days, a 50-70L pack is usually enough. For longer trips, look for a pack that can carry at least 60 L.
Some backpackers have truly mastered the art of thinning down their kit to the bare essentials. However, for most people, a 40L pack will not be large enough for trips longer than a single overnight excursion.
Packing your backpack properly will help you maximize your pack’s capacity and ensure that you feel balanced while hiking with a heavy load. The more organized your initial packing process is, the less you will have to rummage around, looking for stuff during your trip. Knowing how to properly and efficiently pack is an essential part of a successful adventure.
Generally, you’ll want to pack items that you won’t need while hiking near the bottom of your pack. This includes your sleeping bag and extra clothes. The middle of your pack is where you should keep heavier items like food and water. The closer the heavy items are to your back, the better.
Keep frequently used items like rain layers and toiletries near the top of your pack where they will be easily accessible. In your hip strap and top lid, you’ll want to keep things like maps, lip balm, a GPS device, etc.
