Gone are the days when backpacking consisted of strapping on a huge external frame and lumbering through the forest with an aching body. Trends in backpacks these days err towards minimalism and thoughtful, ergonomic design. Below are our favorite backpacking packs for the 2020 season, from ultralight bags for minimalists and thru-hikers to comfort-oriented options for weekend warriors and extended trips. For background information, see our backpack comparison table and buying advice below the picks. To complete your kit, we’ve also tested and written about backpacking tents and sleeping bags.
Weight: 4 lbs. 9 oz.
Fabric: Nylon (100D x 630D)
Capacities: 50, 65L
What we like: Close fit and fantastic back ventilation.
What we don’t: No zipper to the main compartment.
The Atmos AG is our top backpacking pack for 2020 by deftly balancing all of our priorities: comfort, organization, durability, and weight. The attention grabber is the suspended “Anti-Gravity” backpanel, but we like the Atmos because it’s a lot more than just an advancement in pack ventilation. We’ve found it easy to dial in a good fit, the pocket design is thoughtfully laid out (although we’d prefer zippered access to the main compartment), and it’s tough enough for rough treatment while staying well under 5 pounds. Overall, the Atmos is an extremely well-rounded design that works great for anything from quick overnight trips to extended jaunts into the backcountry.
As mentioned above, the most prominent feature on the Atmos AG is its mesh backpanel. Bucking the trend of protruding foam panels that contact your back in certain areas—back, lumbar, and hips—the Atmos AG has a single large ventilated panel that covers the entire back and hipbelt. The result is best-in-class ventilation, and the flexible mesh conforms to your back and waist very well. Impressively, the design manages to carry heavy gear comfortably—we’ve had it loaded with over 45 pounds on more than one occasion—although the mesh is a little less supportive than the foam on a pack like the Gregory Baltoro below. Those looking to shave weight certainly can do so with one of the ultralight choices below, but it’s tough to beat the feature set and build quality of the Atmos AG... Read in-depth review

A Close Second
Weight: 3 lbs. 0 oz.
Fabric: Robic nylon (100D & 210D)
What we like: Excellent mix of carrying comfort, organization, and weight.
What we don’t: Durability and back ventilation can’t match the Atmos AG above.
The Blaze 60 is Granite Gear’s flagship piece, combining heavy-hauling credentials and functional organization at a 3-pound weight. We took the latest model on a difficult trek through the Grand Canyon and were pleased with its overall performance. The pack’s sturdy framesheet and substantial padding on the hipbelt and shoulder straps carried a full load extremely well (it’s rated for 50 pounds), and the zippered opening to the main compartment made it easy to access our gear. Further, the oversized front and side exterior pockets were ideal for storing water bottles (you can fit two standard bottles in one side pocket), a sleeping pad, and rainwear. Most impressively, the Blaze pulls this all off while undercutting most of the competition by 1 pound or more.
What’s not to like with the latest Blaze 60? The padded backpanel favors comfort and support over breathability, and we found it runs warmer than a mesh-heavy design like the Atmos above. Moreover, it takes some practice (and patience) to get the shoulder straps and hipbelt adjusted. In particular, reaching behind the framesheet to remove and reinsert the shoulder strap clips was a pain. But these are very small nitpicks, and the Blaze’s well-rounded build makes it easily one of our favorite packs on the market... Read in-depth review

Best Ultralight Backpacking Pack
Weight: 2 lbs. 0.7 oz.
Fabric: Robic nylon (100D & 200D)
What we like: Ultralight without being overly compromised.
What we don’t: Foam backpanel bunches up.
A number of ultralight packs are designed for thru-hikers and minimalists, but our top pick is the Gossamer Gear Mariposa 60. What sets it apart is how few tradeoffs there are in using this 2-pound 3-ounce bag (ours has a large frame and medium hipbelt). While brands like Hyperlite and Zpacks use Dyneema fabric (formerly cuben fiber) to cut weight, Gossamer Gear uses a light yet tough Robic nylon. This helps keep cost in check, and unlike our Dyneema packs, we’ve had no issues with punctures or wear from the Mariposa. It’s still smart to take extra care when bushwhacking or setting the pack down on rocks, but so far it’s the least compromised ultralight pack we’ve tested.
Organization on the Mariposa is excellent. In addition to the large main compartment, the pack has a total of 7 external pockets of varying sizes, making it easy to distribute your gear. Comfort-wise, we’ve found the Mariposa has sufficient padding and plenty of support right up to its 35-pound maximum rating. If we were to change one thing, it would be the backpanel: the removable foam padding is prone to bunching and we prefer to leave it behind. Otherwise, the Mariposa stands out as the most complete ultralight pack on the market and a great option for backpackers looking to cut weight... Read in-depth review

Most Comfortable Pack for Heavy Loads
Weight: 4 lbs. 15.4 oz.
Fabric: Nylon (210D)
Capacities: 65, 75, 85, 95L
What we like: Heavy hauling comfort with a great feature set.
What we don’t: Pretty heavy and overkill for minimalists.
Gregory has earned a reputation for comfort over the years, and their flagship men’s Baltoro and women’s Deva packs carry on the tradition. These bags are intended to haul heavy loads with strong suspensions, firm but supportive padding, and excellent organization. Gregory modernized the design last year by trimming a few ounces off the previous version, improving ventilation with mesh along the backpanel, and adding a large stretch shove-it pocket at the front. These changes address many of the complaints we had with the old Baltoro, improving one of our favorite packs for shouldering serious weight.
The Baltoro is among the most comfortable and feature-rich designs out there, but it comes at a weight penalty. With its last two updates, Gregory has worked to make it more competitive, but the 75-liter model still comes in at around 5 pounds. If you aim to keep things light and simple on a backpacking trip, this probably isn’t the bag for you. But if you prioritize comfort and appreciate extras like a zippered access to the main compartment, an integrated rainfly, and ample exterior pockets, the Baltoro is a nice choice...

Best of the Rest
Weight: 2 lbs. 0.6 oz.
Fabric: Dyneema (50D & 150D)
Capacities: 40, 55, 70L
What we like: Incredibly light but can carry a full load.
What we don’t: Minimal organization.
Dyneema Composite Fabrics—formerly Cuben Fiber until a recent name change—has arrived on the ultralight backpacking scene in a major way. This unique fabric is among the strongest in the world in terms of strength-to-weight ratio, resists moisture to an impressive degree, and is super lightweight. In outdoor gear, you’ll see Dyneema in ultralight backpacks and shelters with Maine-based Hyperlite Mountain Gear leading the charge. The company makes a number of backpack options depending on conditions and sizing, and we think the 3400 Southwest is their best all-rounder.
At 55 liters, the 3400 (for 3400 cubic inches) has the capacity to take on seriously long trips and has become a go-to pack for thru-hikers. In our hands, it has seen duty as an overnight and multiday backpacking pack as well as a packrafting dry bag. What stands out as most impressive is its ability to haul weight comfortably. Whereas most minimalist models are unable to handle a load, the aluminum stays and firm foam padding provide plenty of structure and support. To be clear, the design is undeniably basic, with only the main compartment and 3 exterior pockets for organization (notably, the hipbelt pockets are now larger and phone-friendly). But for those looking for a pack that can haul serious weight at only 2 pounds, the 3400 Southwest is top of the heap... Read in-depth review

Weight: 4 lbs. 14 oz.
Fabric: Nylon (200D & 420D)
Capacities: 35, 65, 70, 85L
What we like: A well-rounded, comfortable, and very functional pack.
What we don’t: Pushing 5 pounds.
REI’s house brand of packs consistently ramps up quality and features, year after year, while still hitting a really nice price point. Redesigned last year, the large capacity Traverse 70 is no exception. This well-designed pack has thoughtful features like a large J-shaped zipper for access to the main compartment, plenty of exterior pockets, and a rain cover. Moreover, their UpLift compression strap system, which snugs your gear in close, helps take the strain off your lower back and hips. Considering the build quality, features, and comfort, the Traverse is a solid value at $249.
What did REI change with its most recent update? The lumbar support was redesigned to protrude a bit less (we like the firmness of the back support but it’s even more comfortable now). In addition, the old pack had two awkwardly shaped small oval pockets along the front, but the current version has expanded their capacities and includes a generous shove-it space between the pockets and the pack body. REI also improved the removable daypack in a big way (if you’ve used the sash-like design of the old model, you know what we are talking about). Despite those changes and lightening up the pack by just over an ounce, REI kept the core concept of the Traverse the same, which is a good thing... Read in-depth review

Weight: 3 lbs. 9.3 oz.
Fabric: Nylon (100D, 210D, & 420D)
Capacities: 48, 58, 68L
What we like: Well-balanced design with a useful feature set.
What we don’t: Heavier but no more comfortable than the Blaze above.
Gregory's updated-for-2020 Paragon slots below the popular Baltoro above in weight and carrying comfort. But at 3 pounds 9 ounces and a reasonable $230, it’s an attractive option for anything from overnight to extended trips. The pack offers an easily adjustable suspension, plenty of mesh to help you stay cool along the padded backpanel, and a quality feel overall with sturdy zippers and supportive foam. You also get useful extras like a rain cover, large mesh front pocket, and a bear canister-friendly wide shape.
What’s been changed with the latest Paragon? The biggest addition for us is a full-length side zip that allows you quick access to the main compartment (without a weight penalty). In addition, Gregory dropped the old removable day/summit pack (called the “Sidekick”) and replaced it with a standard water reservoir sleeve. As with the Baltoro, we found the Sidekick to have questionable value, so we don’t see this as much of a downside. Finally, the suspension system has been updated with a more body-hugging hipbelt. Taken together, it’s an excellent revamp to one of our favorite mid-range packs.

Weight: 2 lbs. 10 oz.
Fabric: Nylon (100D & 420D)
Capacities: 45, 55L
What we like: Light, comfortable, and a great value.
What we don’t: Limited adjustability for the hipbelt and shoulder straps.
Billed as REI’s ultralight pack, past generations of the Flash 55 were a good value but lacked the true UL chops of designs like Granite Gear’s Crown2 60 or Osprey’s Exos 58. But, as we learned on an ambitious winter backpacking trip in the Grand Canyon, the current version has undergone a significant revamp. It’s now competitively light at 2 pounds 10 ounces (4 ounces more than the Crown2 60 and 1 ounce less than the Exos 58), and REI included thoughtful touches like four large side pockets, seam taping on the lid for water protection, and a convenient roll-top closure. Importantly, comfort wasn’t compromised: we exceeded the recommended 30-pound maximum load by about 5 pounds on our trip (due to a hefty rope), and the suspension and padding handled it with ease.
What truly pushes the Flash line into the ultralight realm, however, is its adaptability. The pack includes a range of removable features—REI calls them “Packmod” accessories—including compression straps, two hipbelt pockets, a shoulder strap pocket, and the aforementioned water-resistant top lid. Depending on the trip, you can throw them on for additional organization or leave them behind and trim 7 ounces off of the pack’s weight. One area where we wish REI hadn’t compromised was fit adjustments: both the hipbelt and shoulder straps are fixed in place and offer limited customization. That said, the Flash lives up to its name and is now a bona fide option for serious ultralight backpackers... Read in-depth review

Weight: 1 lb. 5 oz.
Fabric: Dyneema Composite (2.92 oz/sqyd)
What we like: Incredibly lightweight; very water resistant.
What we don’t: Not very durable.
Weighing at least half a pound less than the next lightest pack on our list, the Zpacks Arc Blast takes the ultralight crown. The 55-liter model we tested comes in at an amazing 1 pound 8 ounces including optional extras like 2 hipbelt pockets. In terms of construction, the Arc Blast uses a similar water-resistant Dyneema (previously called Cuben Hybrid) construction as the Hyperlite above but in an even more streamlined form. This accounts for the low weight but we’ve found it less durable for rough treatment and off-trail scrambling (we got a small puncture in the bottom of our Arc Blast putting it down on a rocky section of trail).
The “Arc” in the name comes from its unique tensioning system that pulls the middle of the bag away from your back, encouraging airflow and alleviating the need for a foam backpanel. Combined with a carbon fiber frame, the pack has a solid structure and provides good support for loads up to about 30 pounds. We wouldn’t recommend carrying much more, however, as the padding is pretty minimal. All in all, the Arc Blast may not be durable or comfortable enough for regular weekend backpackers, but if you treat it with care, it’s an excellent option for serious thru-hikers and minimalist trekkers.
See the Zpacks Arc Blast 55L
Weight: 5 lbs. 0 oz.
Fabric: Nylon (420D & 630D)
Capacities: 50, 63L
What we like: Innovative and functional hipbelt design.
What we don’t: Very, very expensive.
Arc’teryx is known for innovation in outdoor gear, and they recently turned their attention from ski boots to backpacking packs. Building on the excellent rotating hipbelt design of their Altra pack, the Bora AR offers even more mobility and comfort. The RotoGlide, as Arc’teryx calls it, places the hipbelt along a track in the backpanel that allows it to move up and down as you lean forward on a climb. Simply put, nothing else on the market can match this level of customization. In addition, Arc’teryx uses a durable waterproof fabric along the top and front of the bag for fantastic weather resistance. For year-round backpacking in tough conditions and on very rough trails, you won’t find a better option.
As expected from Arc’teryx, the biggest obstacle with the Bora AR is price. Our top-rated pack, the Osprey Atmos AG, is less than half the cost of the Bora and plenty comfortable for most backpacking trips. The Arc’teryx is a better prospect if you’ll be tackling challenging terrain in inclement weather where its defining features—the hipbelt and waterproof materials—truly shine. But it’s a relatively small subset of the market that will value the Bora AR, which pushes it down a few spots on our list.

Weight: 2 lbs. 6 oz.
Fabric: Nylon (100D & 210D)
Capacities: 38, 60L
What we like: Versatile lightweight build.
What we don’t: Becomes less comfortable as you push the 35-pound limit.
More than any other model, the 60-liter Crown has put Granite Gear solidly on the ultralight map. Now in its second iteration—third if you include the old Vapor Trail—the Crown2 is one of the most complete and versatile options available. To start, you get plenty of functional features: Granite Gear’s signature (and elaborate) compression straps, plenty of mesh pockets along the front and sides, and a roll-top closure for securing the load. Further, we love the fit system on the hipbelt, which can be adjusted to your exact waist measurement with a simple but precise Velcro system. As long as you keep your pack weight under the recommended 35 pounds, the Crown2 is a winner.
If you’ll be pushing the Crown2’s weight limit on occasion, however, it may be worth choosing a more comfort-oriented design. The polypropylene frame sheet and thin padding on the shoulder straps and hipbelt just can’t handle a typical full load of gear. But the Crown2 is undeniably an excellent ultralight design and one of the better values on the market at $200. And a final note for true ULers: you can remove the backpanel and top lid to trim weight even further... Read in-depth review

Weight: 1 pound 15.2 oz.
Fabric: Nylon (210D x 200D & 30D)
Capacities: 45, 60L
What we like: Creative and fun UL design.
What we don’t: Can’t carry more than 30 pounds comfortably.
Osprey’s Exos has been their leading ultralight pack model for years, but the sub-2-pound men's Levity and women's Lumina is on a whole new level. We took the 60-liter model to Utah’s Canyon Country and it quickly stood out. Despite weighing 12 ounces less than the Exos, the Levity never felt delicate or compromised. You get a real metal frame that provides a solid structure, excellent ventilation with the suspended mesh backpanel, and the 210 x 200-denier nylon covering a good portion of the pack was plenty durable when brushing up against red rock. All told, we were so impressed with the Levity that’s its overtaken the Exos on our list for 2020.
What are the shortcomings of the Osprey Levity 60? We carried a little under 30 pounds on our trip and were comfortable, but it was clear that the thin padding along the shoulder straps and hipbelt couldn’t handle much more weight. Further, the pack body and sides of the lid use a 30-denier silnylon, which is so thin that it’s see-through (we haven’t put any holes in it, however). But the Levity’s combination of functional organization, excellent build quality, and low weight quickly should make it a top choice among thru-hikers and other ultralight backcountry adventurers...

Weight: 6 lbs. 6 oz.
Fabric: Cordura (500D)
What we like: Premium build quality, super tough, and fantastic carrying comfort.
What we don’t: Extremely heavy and no included hipbelt pockets.
Mystery Ranch is relatively new to the backpacking scene, but the brand can trace the roots of its founder, Dana Gleason, to the legendary Dana Designs packs of the 1990s. From the current lineup, we prefer the heavy-hauling Glacier, which is built to handle rough, expedition-level use and comes loaded with creative design touches. In particular, the floating lid is one of our favorites with its two massive pockets and easy conversion into a functional daypack. And we love the Glacier’s build quality overall—everything from the foam to the zippers has a premium, long-lasting feel.
One of the Glacier’s main competitors is the Osprey Aether below. Both packs offer excellent carrying comfort, durability, and most of the bells and whistles you could want in a deluxe hauler. However, two useful items missing on the Glacier are hipbelt pockets and a large mesh shove-it pocket on the back. The Aether also has better back ventilation with its suspended mesh panel, although it can't match the material quality or toughness of the Glacier. Finally, given its impressive hauling abilities, we’d like to see a larger capacity version from Mystery Ranch like the 85-liter Aether model. But if those nitpicks aren’t deal breakers for you, the Glacier is a wonderfully built pack that’s made to last.

Weight: 5 lbs. 3.4 oz.
Fabric: Nylon (210D & 500D)
Capacities: 60, 70, 85L
What we like: Strong construction and feature-rich.
What we don’t: Most backpackers are still better off with the Atmos.
Osprey’s popular Aether pack is now the Aether AG. The most significant update is the suspended mesh backpanel, which shares a similar design to our top pick, the Atmos AG above. Unlike the Atmos, however, the Aether is more focused on the heavy hauling and light mountaineering crowd and retains a heat moldable foam hipbelt. This gives the pack added support if you have it loaded down with gear. It’s also the more feature-rich Osprey option with a J-shaped zipper to get into the main compartment and an innovative top lid that removes and converts into a complete daypack.
The primary downside of the Aether AG 70 is its weight. The current model actually has gained a few ounces, which puts the empty weight of a medium at a hefty 5 pounds 3 ounces—more than the Gregory Baltoro above. As a result, we think the majority of backpackers will find the Atmos is the better all-around design and a better value. But the Aether still has its place in Osprey’s lineup and on our list if you haul a lot of gear, like the extra features, and need a bomber pack... Read in-depth review

Weight: 2 lbs. 9 oz.
Fabric: Robic nylon (210D)
What we like: Large capacity and fairly durable for the weight.
What we don’t: Weighs more than the ultralight options above.
Utah-based ULA Equipment has gone from a relative unknown to a darling of the PCT and AT in only a few short years. Leading the charge is their Circuit 68-liter pack, which offers an excellent compromise of weight, durability, and functionality for the thru-hiking crowd. The design is streamlined but retains good organization with a very large front mesh pocket and zippered hipbelt compartments. The Circuit is similarly comfortable as the Gossamer Gear Mariposa 60 above, but as with the Mariposa it is recommended that you keep your pack weight under 35 pounds.
The ULA Circuit is differentiated from the other ultralight packs on this list by its durable build. The 210-denier Robic nylon is abrasion resistant and less prone to punctures than the Dyneema Hyperlite and Zpacks designs above. The Mariposa 60 also uses Robic nylon, but it’s a lower denier and as a result a little less tough. That being said, we’ve found the Mariposa to be plenty durable and it gets the edge over the Circuit due to the significant 8-ounce weight savings. But if you’re willing to compromise a little on weight, the Circuit is an impressive high-capacity, sub-3-pound backpack option.
See the ULA Circuit 68
Weight: 2 lbs. 11.5 oz.
Fabric: Nylon (100D & 210D)
Capacities: 38, 48, 58L
What we like: A long-time favorite ultralight design and now with a women’s-specific version.
What we don’t: Thin fabrics and no hipbelt pockets.
Osprey is a backpack powerhouse known for quality builds, excellent organization, and comfort. The Exos 58 was Osprey’s original take on an ultralight pack (also offered in 38 and 48 liter capacities), and is still one of our favorites in this category. The design was lightly updated for last year, including fine tuning the suspension and hipbelt, but the most important change was the release of a women’s-specific Eja version. Both models offer impressive carrying comfort and features for ounce counters and thru-hikers at well under 3 pounds.
What do you compromise by going with the Exos? Durability is the most significant—we’ve gotten multiple small tears in the 100-denier pack body, albeit from the granite and rough rocks of Washington’s Cascade Range. We’re also a little disappointed that Osprey got rid of the hipbelt pockets on the redesign, which we consistently find to be handy for storing small items like a phone or snacks. There are, however, sufficient lash points and mesh pockets on the body of the pack to keep most minimalists happy. If you pack light on your adventures and are willing to take extra care with the thin fabrics, the Exos 58 is well worth a look.

Weight: 3 lbs. 14 oz.
Fabric: Nylon (210D)
Capacities: 60, 75L
What we like: A good price and weight.
What we don’t: Lacking in comfort and only comes in one size.
The Aircontact Lite (previously the ACT Lite) is Deuter’s entry-level pack and was updated last spring. We’ll start with the positives: it’s priced well at $200 and reasonably lightweight at 3 pounds 14 ounces. In terms of capacity, the “+ 10” in the name refers to the expandable top portion of the main compartment. This allows you to compress the load if you’re packing light and only need 50 liters, or you can extend it to store a typical multi-day trip’s worth of gear. Throw in the Aircontact’s streamlined but functional organization and quality materials, and you have a compelling backpack design.
However, we recently took the Deuter Aircontact Lite out in Utah and came away unimpressed. Most notably, the backpanel was not very comfortable, and in particular the hard Vari Quick adjustment centerpiece pressed into our back while hiking. Further, the tall and thin design didn’t do the trick for us. It was more difficult to pack and access gear than other models we’ve used and didn’t make the Aircontact perform better on the trail. Finally, the pack only comes in one size with the aforementioned torso height adjustability. This made it feel small—we usually wear a medium or large—and we prefer at least two size options. But we do like the price and weight, which are why the Deuter makes this list.

Weight: 4 lbs. 13 oz.
Fabric: Polyester (420D)
Capacities: 65, 80L
What we like: Cheap and surprisingly comfortable.
What we don’t: Not as good for heavy loads.
Kelty generally targets the entry-level end of the camping and backpacking spectrum, but we appreciate the reasonable prices and sturdy builds. The Coyote is their long-running multi-day offering, available in 65 and 80 liter capacities (60 and 70 liters for the women’s-specific design). There isn’t anything fancy in the construction, but it offers decent organization, a tough 420-denier polyester on the pack body, and strong aluminum frame. All told, it’s a worthy option for first-timers, weekend trips, and just about anyone else who wants to keep the tab under $200.
The signature feature on the Coyote is the “Perfect Fit” system: instead of making the pack in a few different sizes, an on-body adjustment system allows you to dial in fit around your waist, torso, and shoulders (this even means that you can share the pack or lend it to a friend). On the trail, you’ll find that the padding, zippers, and materials aren’t as high-end as the pricier packs above, and it isn’t ideal for carrying ultra-heavy loads or covering tons of miles. But the Coyote is a proven design that hits a very desirable price point. And we want to give a quick shout-out to Kelty for continuing to make external-frame packs like the Trekker 65. The practicality may be limited, but these old-school designs have a loyal following and it’s fun to still have them available.

Weight: 3 lbs. 8.5 oz.
Fabric: Nylon (600D and 1000D)
Capacities: 50, 65L
What we like: Cheap, well-built, and reasonably light.
What we don’t: Poor marks on comfort and organization.
We’ll start by calling out the main reason the Osprey Rook is included here: price. At $165, it’s the cheapest model on the list and happens to be made by the industry’s leading backpack manufacturer, which is quite a combination. In addition, the Rook is well-built and extremely tough: the 600D/1000D polyester and nylon build is by far the thickest we’ve tested, even beating out the 6-plus-pound Mystery Ranch Glacier above. Last but not least, the Rook manages to weigh in at a reasonable 3 pounds 8.5 ounces. On paper, it’s one heckuva deal.
In practice, we didn’t love the Osprey Rook. The pack is lacking in comfort and almost totally bereft of features. We took it down into the Grand Canyon on a multi-day backpacking trip and were always quite happy to take if off when arriving at camp (that’s often the case with packs, but even more so with the Rook). Moreover, it has minimal organization overall, lacks a front shove-it pocket, has awkwardly sized water bottle holsters, and is only made in one size (with four levels of torso adjustability nevertheless). But for beginners or those looking for a new pack on a budget, the Rook is a serviceable option... Read in-depth review

- Pack Sizing: Know Your Torso Measurement
Rules about how big of a pack you need are not hard and fast. Multiple factors come in to play such as how many nights your trip is and what time of year you are backpacking (bulkier gear is needed for cold weather). One point should stand out, however. Make sure to match your pack's capacity to your type of gear you'll be bringing. Do you have dated gear that doesn't compress well, or do you like to bring along a few extras? Then make sure to get a correspondingly cavernous pack. Sizing down to a lightweight modern tent and down sleeping bag will allow for more flexibility in size options.
The majority of backpackers take short trips, usually in the 1-3 day range, and for those uses, a pack in the 50-70 liter range is most popular. With a pack like the Osprey Atmos AG 50, you’ll need to keep your packed weight low, stick to the essentials, and be sure to use the aforementioned compressible gear. While at 60 liters and more, you have enough space to take on a few additional items—great for parents with kids in tow. Within each of the ranges we have listed below, you can follow those general guidelines: minimalist to bulky (or a lot of) gear.
- Overnight: 35-55 liters
- Weekend (2-3 nights): 45-70 liters
- Extended trips (over 3 days): 60+ liters
Looking beyond how much space your gear takes up in a pack, it’s also important to ballpark the total weight. If your gear is older or you prefer a comfort-oriented (read: heavier) setup, it’s a good idea to get a pack that can handle the extra weight. Alternatively, if you’re into minimalism and ultralight gear, you can get away with a corresponding lightweight pack. In looking at backpacks, relevant considerations for hauling ability are the pack’s frame, suspension and padding. One quick reference point is the pack’s empty weight, which is provided for nearly every model sold.
A heavier pack is logically most often capable of hauling more weight. It will have a beefy frame, tough fabrics and thick padding. There are some exceptions, and backpacks overall are becoming lighter—take for example the Gregory Baltoro, which dropped a lot of weight between models (about 9 ounces to get down to 5 lbs.), but is still adept at comfortably handling a heavy load. Below is a basic guideline in matching pack weight and hauling ability. Note, some manufacturers also provide load ratings for their packs, which is another helpful reference point.
- 2-3 lb. pack weight = 15-35 pounds of gear
- 3-5 lb. pack weight = 30-50 pounds of gear
- 5+ lb. pack weight = 40-70 pounds of gear
The thickness and quality of the padding found in the backpanel, and particularly the shoulder straps and hipbelts, is an important consideration in choosing a pack. A properly set up pack will place most of the weight on your hips, with the shoulder straps taking a light amount of weight and keeping the pack tucked in close to your back. The foam and the fabric that covers it do add weight, so manufacturers are always trying to find the right balance weight and comfort. All non-ultralight overnight, weekend and extended travel packs feature foam padding to increase comfort. We prefer foam that errs towards firm support rather than being soft and compressible. Excessively soft padding might feel great when first trying on a pack, but it doesn’t offer the long-term support needed for hauling heavier loads. Packs like the Gregory Baltoro and Arc'teryx Bora AR are great examples of effective use of this type of high quality, firm padding.
Very lightweight gear sometimes goes without even a whiff of foam in the hipbelt and/or shoulder straps, so it’s an absolute necessity to keep your loaded weight to a minimum. Some ultralight packs do a decent job of balancing these needs, including the Osprey Exos 58, which uses a creative mesh design surrounding thin foam for a good balance of weight and support. Nevertheless, we don’t recommend packing much more than 30 pounds in an ultralight pack—and it’s often better to keep it closer to 25.
When you’re playing the part of a moving van, carrying all your possessions in one place, organization is of utmost importance. This is where the old external framed packs had a distinct advantage – pockets and organization galore. It’s not to say internal framed packs aren’t improving, however, with numerous access points and creative packaging.
Main Compartment Access
Nearly every backpacking pack out there will have an opening at the top that is secured in a cinch cord or roll-top manner, referred to as a top-loader. Additional access to the bottom or middle of the pack via a u-shaped zipper can be a big help, keeping you from having to shovel through a once-meticulously organized pack to find some elusive item. These extra zippers add a little weight, but are often worth it. In cases like the Gregory Baltoro or Osprey Aether AG, the u-shaped opening is so wide that you can pack and remove items much like a travel suitcase.
A top lid with zippered pockets is a great spot for some lighter weight items that you might need on quick notice, like a headlamp. External floating pockets are becoming popular to stuff gear like a rain jacket or insulated midlayer. Hipbelt pockets are another recent adoption for putting quick access items like lip balm, a camera or lifesavers (an excellent energy booster on the trail). And finally, don’t forget about exterior attachment points or loops for an ice axe or trekking pole.
Compression straps along the sides of the pack not only pull the weight of the pack closer to your back, but are also a great spot to store taller items like tent poles. Make sure the pack you’re looking at has these side compression straps towards both the top and bottom to aid in load stability. Granite Gear and REI do a great job of incorporating creative compression strap systems to keep the weight of the pack snug against you. The UpLift design from REI on their Traverse 70 pack is notable in that it pulls the pack’s load into a focused area along your lower back—exactly the place you want to be carrying the majority of the weight.
Backpanel and hipbelt ventilation is a biggie for some (this author included). Finding an internal framed pack that breathes well can be a challenge, primarily because the point of the pack is to hug and conform to your body, moving with you as you walk. A typical pack will have offsetting foam and mesh panels that try to encourage airflow, but what that usually results in is sweat art on your back that traces where the foam panels are contacting you. The Anti-Gravity system from Osprey, with its full-length mesh that even includes the hipbelt, is an impressive design that offers best in class ventilation. We loved the design, although there are a few sacrifices in choosing this type of pack (see our in-depth review of the Atmos AG).
Many items that we store in our backpacks are vulnerable to moisture—including a camera, phone, and down sleeping bag—so we place a high priority on water protection. The good news is that most backpacks offer decent water resistance with hard-face nylon, but sustained rainfall will penetrate the fabric. For heavy rain, some packs include a built-in waterproof cover that stores inside the pack (from our list, the Gregory Baltoro 65, REI Traverse 70, and Gregory Paragon 58 have this feature). Alternatively, you can purchase a separate rain cover, and we like Osprey’s UltraLight Raincover best: it weighs just over 3 ounces, packs down small, and fits snugly around a decent range of pack sizes.
There are also a number of highly water resistant backpacks on the market. Bags made with Dyneema (previously known as Cuben Fiber) naturally are waterproof, which is a key benefit to the ultralight fabric. We’ve used the 100% Dyneema Hyperlite Windrider as a dry bag (see our in-depth review) and it didn’t let us down. Among nylon and polyester designs, Arc’teryx uses a waterproof material for a good portion of their Bora AR backpack, although it’s not fully waterproof like a Dyneema bag.
While it sounds well and good—reducing weight to move easier and faster—going to an ultralight pack is not without compromise. First off, know that you are forgoing most luxury items. You’ll see simplified organization, reduced padding, and a more basic frame—some even go without metal stays (metal rods that give the pack a rigid structure) completely. The pack’s fabric will also be thinner in the quest to cut weight (you'll see this referenced as a lower "denier" or "D" in our comparison table), making it more vulnerable to tearing when cutting through brush or squeezing between rocks. And because it’s the piece of gear that will be hauling the rest of your stuff, commit to moving your entire setup to ultralight status. If not, the extra weight will overwhelm the pack’s suspension, making for some miserable trekking.
If you’re getting a negative impression from our thoughts on ultralight packs, don’t! They’ve become a mainstay for thru-hikers and lightweight backpackers, and have numerous tangible benefits. Most importantly, there’s reduced stress on all your joints by hauling less weight, so you can cover more miles with less effort (and less pain). And improvements in pack materials and suspensions are making many of the compromises above a non-issue.
Standout ultralight packs that made our list include the Gossamer Gear Mariposa 60, Osprey Levity 60, Zpacks Arc Blast 55L, Hyperlite 3400 Southwest, and ULA Circuit 68. The Zpacks and Hyperlite are made with Dyneema Composite Fabrics (previously known as Cuben Fiber), which is an extremely lightweight but strong fabric—it resists tears far better than an ultralight nylon. Moreover, smart use of padding and support makes the Zpacks and particularly the Hyperlite handle weight surprisingly well. The final benefit is that the Dyneema fabric is highly resistant to water, which means you don’t have to worry about bringing a rain cover. Done right, an ultralight pack is a deserved replacement to your old faithful traditional pack.
The number one factor in sizing a backpack is your torso measurement. No matter the adjustability of a pack, if you get one that doesn’t fit your torso, you’ll find yourself perpetually adjusting and tweaking a pack that will never fit. Trust us, spend the 10 seconds and get yourself measured.
What you need: A flexible cloth tape measure and another human. Please don’t try to get the measurement yourself. Even if you have Cirque du Soleil levels of flexibility, you won’t get your size right.
What to do: Start by putting your chin to your chest and have your helper locate the C7 vertebrae near the base of the neck. It’s the largest vertebrae in the neck and sticks out the most, so it should easy to find. Next, rest your hands on the top of your hips in the same way your parents used to do when you failed to clean your room – with your thumbs along your back. That top part of your hips is your iliac crest, the ideal place for a hipbelt to rest and do its job of carrying most of the pack’s weight. Have your new friend then measure from the C7 vertebrae to the spot on your spine where your thumbs would meet. Voila, you have your torso measurement. If you're more of a visual learner, REI put together an informative video and article on how to get your torso and hip size.
If you’re having trouble finding a pack that fits both your torso and waist measurements, pick one with replaceable hipbelts. You can then choose the size of pack you need based on your torso measurement and swap out the hipbelts. A number of the packs we recommend have these replaceable pieces (REI Traverse, Osprey Aether AG, and Gregory Baltoro). Alternatively, some packs offer precise adjustments for both the torso and hipbelt to really dial in the fit.
