Backpacks come in many sizes and flavors for a reason: so do backpackers. Some of us need a pack for moderate loads, others for heavy loads, while still others want a pack designed for lightweight or ultralight backpacking. Some prefer a minimalist design, others a range of features and access. Everyone wants the best fit and comfort they can find, and almost everyone has a budget.

I looked at all the backpacks intended primarily (if not exclusively) for backpacking that I’ve tested and reviewed at The Big Outside, and selected for this article 10 top performers that stand out for reasons that make each appeal uniquely to a certain type of backpacker. (In addition, I point out below two excellent packs for kids of all ages.) I think one of them will be perfect for you—possibly even more than one if, like me, you prefer different packs for different kinds of trips.

I’ve listed the packs alphabetically rather than ranking them by some performance metric, because the one you choose will depend most on the type of pack you’re seeking and on your budget. I suggest you narrow your choices to two or three and try them all on. If you’re unsure what type of pack you need, you may want to first read my “5 Tips For Buying the Right Backpack.” The comparison chart below offers a quick look at stats and features that distinguish these packs from one another.

The generously padded, removable Rotoglide hipbelt in the Bora packs—which come in 63- and 50-liter versions for men, and 61- and 49-liter versions for women—rotates side to side and slides up and down, eliminating fatigue and soreness that some packs cause in the shoulders and back as trail miles accumulate. The very light, thermo-molded Tegris framesheet with two aluminum stays provides support for carrying at least 40 pounds, while the shoulder straps are widely adjustable for both shoulder width and torso length. Add to that superior comfort features like a wide mouth and bright interior for loading, a huge front pocket, four more pockets on the sides and hipbelt, and bombproof fabric that’s waterproof in high-exposure areas, and you have a high-tech hauler that could be the last backpack you own.

Big-Load Hauler
Gregory Baltoro 75 and Deva 70
$319, 6 lbs.

For carrying loads of 50 pounds or more, I want a pack that’s supportive, comfortable, and more tricked out than I prefer in a lighter pack. In every respect, from the suspension to the feature set, the men’s Baltoro and women’s Deva packs fill the big-pack role extremely well. The suspension sports an independently pivoting shoulder harness and hipbelt that let the pack move with your body, and the thermo-molded back panel and lumbar pad deliver serious cushioning. Features include a weatherproof hipbelt pocket for electronics; a removable, Sidekick internal hydration bladder that doubles as an ultralight summit pack; a lid pocket that converts to a fanny pack; a U-shaped zipper to access the main compartment; and multiple pockets. The Baltoro also comes in 65-liter ($299) and 85-liter ($349) versions, and the Deva in 60-liter ($299) and 80-liter ($319) versions.

Good Value
Gregory Stout 45 and Amber 44
$169, 3 lbs. 9 oz.

For a backpacker who travels fairly light, may wander into rugged terrain, and pursues adventures on a budget, it’s hard to beat the men’s Stout and women’s Amber packs. With the support for carrying up to 35 pounds, the Stout 45 and Amber 44 have design features you’d expect in more-expensive backpacks: an ample lumbar pad; an adjustable hipbelt with good rigidity; a steel alloy, perimeter frame; wicking mesh in the back panel, and a curved shape that allows some air flow over your back. The fixed, non-adjustable harness comes in two sizes (not the usual three sizes of other Gregory models). The Stout also comes in 65-liter ($199) and 75-liter ($219) versions, and the Amber in 34-liter ($149), 60-liter ($199), and 70-liter ($219) versions.

Ultralight Standout

$340, 55L/3,400 c.i., 1 lb. 15 oz.

Many ultralight packs lack the support for carrying more than about 25 pounds comfortably. HMG’s 3400 Windrider handles 30 to 35 pounds well, has the capacity for going several days between resupplies, and weighs much less than some best-selling competitors. Its tough Dyneema Composite Fabrics is fully waterproof. The fixed suspension comes in four sizes—more than offered by most high-end pack makers—and the simple harness system works. Three big, external mesh pockets add nearly 10 liters of capacity, and the roomy, zippered hipbelt pockets offer convenience. A top-loader with a roll-top closure, the 3400 Windrider is noticeably bereft of features found on many other packs. But its minimalist design, durability, capacity, comfort, and low weight will appeal to many backpackers who prefer hiking over simply hauling.

Ultimate Carrying Comfort
Osprey Atmos AG 65 and Aura AG 65
$260, 4 lbs. 11 oz.

The men’s Atmos AG and women’s Aura AG (lead photo at top of story) packs feel different the moment you put one on: The Anti-Gravity suspension feels more like putting on a jacket than a backpack. And they carry 45 to 50 pounds with supreme comfort, wrapping around your back and hips while allowing air to move across your back. These packs are available in three sizes with an adjustable harness and hipbelt, and come loaded with features including multiple pockets and a convenient trekking poles attachment on the left shoulder strap for tucking them away on the go. And it weighs well under five pounds. It’s a great choice for backpackers who usually carry moderate to heavy loads.

Lightweight Pick
Osprey Exos 58
$220, 2 lbs. 8 oz.

When I’m not carrying extra gear for either my family or a gear-intensive trip like climbing, I keep my pack weight, even with food for several days, to around 25 pounds or less (and it’s only that heavy partly because of camera equipment, but also because of personal choices; see my ultralight backpacking tips). But I also walk many miles and hours each day, so I don’t want to sacrifice comfort by getting a pack with no real suspension or support. The Exos series demonstrates that a backpack weighing a mere two-and-a-half pounds can carry 25 to 30 pounds comfortably, thus serving the needs of everyone from weekenders to longer-distance backpackers and thru-hikers. The Exos also comes in 48-liter ($190) and 38-liter ($160) versions.

Best Price
REI Flash 45
$149, 2 lbs. 14 oz.

REI’s latest iteration of the Flash 45 does two things rarely seen in a quality backpack: It weighs in under three pounds and costs less than $150. It carries 25 to 30 pounds comfortably, has some adjustability in the shoulder harness, and sports REI’s proprietary UpLift Compression system, ratcheting straps that pull the pack load upward and inward to both make the load more stable and shift it closer to your center of balance. A basic top-loader, it has the capacity for a three- to four-day trip, plus six external pockets. You can find packs that are more comfortable, feature-rich, minimalist, or capable of hauling more weight, but you will be challenged to find one that compares with the Flash 45 at a better price.

Many avid backpackers eventually find themselves facing an expensive quandary: the need for a second or even third pack to better handle the range of trips they take. Sierra Designs confronts that challenge with the Flex Capacitor, which changes size in a range from 40 to 60 liters to cover trips from weekends to a week or even a thru-hike. I found it comfortable carrying up to 35 pounds on the Tour du Mont Blanc—impressive for a pack weighing slightly more than two-and-a-half pounds—and I suspect many people would find it hauls 40 pounds well. While organization and access don’t match other packs on this list, there are five external pockets, including roomy hipbelt pockets, and it’s durable for its weight class.

Pound-For-Pound Standout
The North Face Banchee 65
$239, 3 lbs. 12 oz.

I’ll admit, I didn’t expect a pack weighing under four pounds to carry upwards of 50 pounds comfortably, but the Banchee 65 did that—albeit just for a few hours—when I had to haul extra water for my daughter and myself in the Grand Canyon. While I don’t put it in the same weight class as the Gregory Baltoro/Deva, Arc’teryx Altra, or Osprey Atmos/Aura AG packs, the Banchee 65 certainly hauls 40 pounds quite comfortably all day. A top-loader, it excels for organization, with nine pockets from the hipbelt to two 16-inch-long, zippered front pockets. With its modest weight and good compression, the Banchee 65 is legitimately all the pack you need for trips from overnighters to weeklong wilderness treks, as long as you don’t routinely load more than 40 to 45 pounds inside.

Super Organization For Big Loads
The North Face Fovero 70
$290, 5 lbs. 7 oz.

For hauling around 40 pounds or more, I want a pack that’s built for heavy loads and has a high degree of organization. Backpacking in Idaho’s Sawtooth Mountains with my teenage son and two of his new-to-backpacking buddies, I found the Fovero 70 delivered exceptional comfort and access. The adjustable harness in the men’s and women’s models has five inches of range for dialing in a good fit for your torso length, and the hipbelt pads are adjustable. Most distinctively, this top loader has better access and organization than many packs in this category, starting with nine pockets—including on the hipbelt, mesh side pockets, two roomy, zippered front pockets, and a voluminous “beaver-tail” (AKA stuff-it) front pocket. And a J-shaped, two-way zipper runs down one side and around the bottom, giving quick access to much of the main compartment.

12 Responses to Gear Review: The 10 Best Backpacking Packs

  1. Aaron Martin   |  September 21, 2016 at 5:04 pm

    For someone that is beginning to the transition into lighter gear but wants a pack for weeklong trips, would you suggest the Altra or Atmos? From this I can’t quite tell which you think is more comfortable.

    • Michael Lanza   |  September 21, 2016 at 5:17 pm

      Hey Aaron, good question. When you say “lighter gear,” your pack choice will depend on what you really mean by that in terms of total weight. You could have a total pack weight of 25 pounds (or less), including food and water for a weeklong trip; certainly under 30 pounds isn’t hard to achieve. The Altra and Atmos are both very comfortable with 45+ pounds, and that’s what they’re made for. If your regularly carrying that much weight, I would try them both on loaded with some weight and see which feels better on you, and also consider which feature set you prefer.

      When choosing a pack, I always tell people to find a few options that look good and try them on. See my “5 Tips For Buying the Right Backpack:” https://thebigoutside.com/5-tips-for-finding-the-right-backpack/

  2. Joey Alcala ن (@JoeyDoulos)   |  August 30, 2016 at 5:08 pm

    Which of these packs would fit as a carry on?

    • michaellanza   |  August 30, 2016 at 5:54 pm

      Hi Joey, I’ve used the REI Flash 45 as a carry-on; its frame is flexible. I think the Gregory Stout 45/Amber 44 might be borderline, but would probably fit on larger jets. Exped Thunder 50 is probably a little too large, but I haven’t tried it. The rest are bigger packs.

  3. Brad   |  April 18, 2016 at 6:24 pm

    Where are the lightweight packs made by smaller companies? I would not buy any of these packs. They are all overpriced and weigh too much. Hyperlight Mountain Gear, Gossamer Gear, Mountain Laurel Designs, ZPacks and ULA are making the best backpacks. My big HMG pack can handle the weight that these packs do, and weighs less and feels better.

    • michaellanza   |  April 20, 2016 at 9:35 am

      Hi Brad, those are good brands, I’ve used packs made by some of them and may test and review a pack from at least one of these companies in the future. Then I’ll judge whether it deserves to be on this list, which covers the best packs for backpacking that I’ve used so far. I’ve tested and reviewed dozens of backpacks over the past two decades, and I’ve liked some ultralight packs; but they may not be as ideal for many users as they are for you, based on my personal experience and the clear demands of consumers.

  4. Joe   |  March 30, 2016 at 4:10 pm

    Hi Michael,

    Thanks for the article. I recently purchased an AARN pack and found it excellent, was wondering where your thoughts lay with this brand of backpack,

    Many thanks

    • michaellanza   |  March 30, 2016 at 5:44 pm

      Hi Joe, I’ve seen AARN packs but haven’t had the opportunity to try one out yet. So while I can’t really comment on that brand specifically, I did, for many years, use sizable front packs for carrying camera equipment, which is a setup similar to the way AARN packs distribute weight front and back. I eventually decided that I don’t like having a fairly large pack on my chest, because it’s hot and obstructs my view of where I’m walking. By the way, I now carry my camera equipment and small incidentals (like a map and snacks) in a Ribz Front Pack, which is much less obtrusive: https://thebigoutside.com/gear-review-update-ribz-front-pack/

  5. Garry Hall   |  March 30, 2016 at 9:20 am

    I like Ospery Aether, Xenith packs they just Carrie much better than the packs you have on your list I have been to EMS stores and REI and many of the packs that you list have a lot of returns but Aether and Xenith packs are the ones they push and I must say I tried the packs you talked about but after days hiking with them I always go back to the Ospery Aether ,Xenith these packs just feel so much better on my back they make the weight disappear and after days of hiking that is the key to enjoying backpacking .

    • michaellanza   |  March 30, 2016 at 9:31 am

      Hi Garry, I’ve used both the Aether and Xenith (and reviewed the Xenith here: https://thebigoutside.com/gear-review-osprey-xenith-88xena-85-backpacks/). Yup, they’re very good. The Xenith is obviously built for heavy loads, and there’s no reason to carry a pack that heavy for lighter loads. I think Osprey has improved on its harness technology with the AG harness in the Atmos and Aura packs, which can handle pretty substantial loads. The other packs reviewed here have a variety of strengths and are designed for different loads and styles.
