Gear Review: The 10 Best Backpacking Packs of 2019

Gear Review: The 10 Best Backpacking Packs of 2019

By Michael Lanza

Backpacks come in many sizes and designs 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 pack, others a range of features and access. Everyone wants the best fit and comfort they can find, and almost everyone has a budget.

This review covers my picks for the 10 best backpacks intended primarily (if not exclusively) for backpacking—covering a range of designs, each one a standout for different reasons. In addition, I point out below two excellent packs for kids of all ages. My judgments draw from my experience of many thousands of miles of backpacking over three decades and a quarter-century of testing and reviewing gear—first for Backpacker magazine, and now for this blog. I think at least one of these packs will be perfect for you—plus you’ll find some at great sale prices now (and links to those online retailers below).

I’ve listed the pack reviews below in order by weight because that’s the metric that most defines and influences a pack’s design and functionality. The pack you ultimately choose may depend partly on weight, but also on design and on your budget. Each pack review in this article links to that pack’s complete review at The Big Outside. I suggest you narrow your choices to two or three and try them all on.

Not sure what type of pack you need? Start with 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.

Tough, Waterproof Ultralight

Hyperlite Mountain Gear 3400 Windrider
$345, 55L/3,400 c.i., 1 lb. 15 oz.

When the 3400 Windrider was delivered to my house, the box looked much too small to contain a backpack. Comparable to the best sub-three-pound, ultralight packs, the 3400 Windrider handles 30 to 35 pounds well, but weighs anywhere from a half-pound to nearly a pound less than those competitors. It has the capacity for going several days between resupplies. 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.

Backpackers who want to go ultralight without switching to a stripped-down style of backpack will like the traditional design of the top-loading men’s Optic and women’s Octal. They sport six external pockets, including two on the hipbelt and a large, stretch-mesh front pocket, and useful features like a quick attachment on the left shoulder strap for trekking poles or sunglasses.

Gregory’s attention to comfort in its first ultralight backpack is reflected in the aluminum perimeter wire with an HDPE framesheet and leaf-spring lumbar pad, which distributes most of the pack’s load across the hips and delivers support for carrying 30 to 35 pounds; and the trampoline-style Aerospan suspension, a tensioned, highly ventilated back panel that allows air movement across your sweaty back. These are well-designed, comfortable packs for ultralighters who want some organizational features of traditional backpacks.

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—solid performance 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.

Redesigned for 2018, the classic Exos still sets standards for ultralight backpacks—and Osprey rolled out a women’s version, the Eja. Available in three torso lengths, its alloy perimeter frame has a pronounced bell shape that helps focus the load more directly onto the hips—an improvement in comfort that’s noticeable, allowing the pack to carry 30 pounds or more comfortably. And the trampoline-style back panel permits cooling air circulation.

The Exos 58 and Eja 58 have the capacity for weeklong trips and ultralight thru-hiking. At just over 2.5 pounds, they have smart features like a removable lid, voluminous exterior pockets, and a handy trekking poles attachment on the left shoulder strap. The Exos and Eja also come in 48-liter ($200) and 38-liter ($180) versions.

Best Price

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

REI’s latest iteration of the men’s and women’s 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.

Most Versatile

Granite Gear Blaze 60
$270, 3 lbs. 4 oz.

How many pounds can a lightweight backpack carry comfortably? The Blaze 60 may have redefined that. At just a half-pound heavier than some ultralight packs, the Blaze 60 has the comfort and support to haul 40 pounds or more, as I discovered on long days during a 74-mile backpacking trip through the Grand Canyon. Coming in three unisex and two women’s sizes, all of them adjustable for torso length, it fits nearly all of humanity.

It has the capacity and support for long trips and the compression and low weight for short trips, plus super access with a wide top-loading mouth, a panel zipper into the main compartment, and six external pockets. On top of all that, the fabric is bombproof. The Blaze 60 deserves a place among the top all-purpose packs for trips of any length.

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 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 Bora AR 50, 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.

The men’s Atmos AG and women’s Aura AG 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.

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.

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—updated and a pound lighter for 2018—fill the big-pack role extremely well.

The suspension allows both shoulder straps and both sides of the hipbelt to pivot independently, letting the pack move with your body, while the high-strength aluminum perimeter frame and the ventilated, moisture-wicking mesh back panel and foam lumbar pad deliver serious support, cushioning, and comfort. Features include a U-shaped zipper that opens up the entire main compartment; multiple pockets, including a weatherproof hipbelt pocket that holds a smartphone, and a dual-pocket lid; a removable, Sidekick internal hydration bladder that doubles as an ultralight summit pack; a quick attachment for sunglasses on a shoulder strap; widely adjustable compression straps that cross over the pack bag; and a rain cover included. Other capacity options are the Baltoro 75 ($330), Baltoro 85 ($350), and Baltoro 95 Pro ($380), and the Deva 70 ($330) and Deva 80 ($350).

  1. Jeff

    I have a REI flashpack 65 can you comment on this bag?

    • Michael Lanza

      Hi Jeff, thanks for that question. Since REI no longer carries the Flash 65 backpack, you must have an older model. I used and liked the previous version of the Flash 45, too, which is very similar to the pack you have if you have the same generation of that pack series. The latest Flash packs have some improvements, most notably REI’s UpLift compression system, mentioned in my review above. Click on the link to the complete review (linked in the above story) for more details on the new model. If you’re considering a new pack and liked the previous Flash, you may like the new one even more.

  2. Aaron Martin

    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

      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 Arc’teryx Altra is no longer available, but the Osprey Atmos AG is very comfortable with 45+ pounds, and that’s what it’s made for. If your regularly carrying that much weight, I would try it and other big packs in this review 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.”

    • michaellanza

      Hi Joey, I’ve used the REI Flash 45 as a carry-on. The smaller versions of the Gregory Optic and Octal and the Osprey Exos and Eja would probably work, as well as the Sierra Designs Flex Capacitor.

  3. Brad

    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

      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

    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

      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:

  5. Garry Hall

    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

      Hi Garry, I’ve used both the Aether and Xenith (and reviewed the Xenith here: 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.
