The Granite Gear Blaze 60 is the best overall backpacking pack in our review thanks to its impressive design that somehow pulls off comfortably supporting up to the fifty-pounds of weight, while only weighing a feathery three pounds. We also loved the overall execution of features on this pack: stretchy mesh stuff-it pocket, roomy hip pockets, removable top-lid, breathable back-panel, long front access zipper, compression straps with clipping buckles, this thing has it all. It's ideal in both weight and weight-capacity. Being so light helps keep the base weight down, but because it has such a strong suspension, it can still comfortably carry a few extra pounds when you need it to.

While this pack does a lot of things right, it's impossible to please everyone. The buckles are small and, therefore hard to operate with gloved hands. It also no high tech revolutionary pack, but that's part of the appeal. They keep things simple and to the point using the lightest and most durable fabrics possible.

The Osprey Atmos 65 AG is one of the best all-around backpacking backpacks due to its stellar design and overall comfort. It's full of functional features, fantastic ventilation, and weighs in at a respectable 4 lbs 8 oz. However, what sets this pack apart from the rest of the packs in its class is its innovative anti-gravity (AG) suspension, which spreads the pack load evenly across the back. The pack feels light, and the tapered foam shoulder straps are dreamy. For average trips with loads at or under 40 lbs, this is the most comfortable pack in our review. Every pocket is the right size and in the right place. Moreover, the Atmos offers an excellent fit with its efficient adjustability focused on ergonomics.

While this is a great all-around pack, it doesn't handle loads above 45 pounds well. Consider a different model if you consistently carry that much or more. Also, if you take this pack out in the winter or early spring before the thaw, it's worth noting that snow can get caught in the AG suspension. However, for most trips in most seasons, this pack is the one that will have you not only enjoying your destination but the journey that got you there as well.

The ULA Catalyst is for the true backpacking enthusiast. This pack hardly registers on the scales weighing only three pounds yet comfortably carries a hefty resupply for your next desert section of the PCT. ULA has been known by the trail community for years as having features that hikers love like massive hip belt pockets, huge stretchy mesh stuff-it pockets, and huge bottle pockets. Heck, for an upcharge, they will even embroider your trail name. They offer nine different color options and even do fun customized color combinations. This is all great stuff, but when it comes down to it, this pack scores so well in our test by simply being a capable, comfortable, feature-filled pack.

This pack isn't quite perfect for everyone, however. If you are one to prioritize a trampoline style back-panel for breathability purposes, this pack may not interest you. This pack also has no top-lid, however, we found we still had ample storage for on the go items. This pack gave the Editors' Choice a run for its money.

If you want an affordable pack that doesn't skimp on performance, you can't go wrong with the Osprey Volt 60. It is an inexpensive pack that is still comparable in functionality to pricier models. We are wholly impressed by how capable and comfortable this backpack is with loads under 45 pounds. While simple, the Volt 60 includes all the essential features that most travelers are looking for, including two zippered lid pockets, dual entry water bottle pockets, a stretchy beavertail pocket, and a lower zippered access point (AKA sleeping bag compartment). With everything it offers, it still weighs in at just over four pounds. Aspects that propel this model over the rest are the ergonomic shoulder harness, high-quality foam padding in the shoulder straps and waist belt, and the comfortable fabrics.

The Volt doesn't go above and beyond with additional features, nor does it have the burliest suspension, but it does excel in pure functionality. It only comes in one frame size, but the vertical adjustment is large enough to accommodate most people. Unless you are regularly carrying loads over 45 pounds, we recommend that you strongly consider this pack.

Arc'teryx doesn't pull any punches when it comes to performance. The shoulder straps use a therapeutic-mattress-feeling foam that strikes an idealistic balance between cushy comfort and excellent support. The features are well thought-out and incredibly user-friendly. While the pivoting waist belt might appear gimmicky at first glance, it extremely efficient at transferring the weight from the back to the hips, especially in both rough and steep terrain.

The primary drawback to this pack is its slightly above average weight (five pounds) and its top-of-the-review price tag. Still, the tradeoff is getting the most water-resistant model in our evaluation. The Bora employs the proprietary AC² fabric which covers most of the pack, sealing some seams, and integrating some watertight zippers. This combination kept our gear dry during wet springtime hikes in the soggy rainforests of Olympic National Park.

If you frequently go on extended technical outings or trips that require you to carry a lot of gear, the Osprey Xenith 105 is the pack for you. The Xenith is tester Ian Nicholson's favorite pack for Denali expeditions where he is out for 22-days at a time in the arctic cold carrying heavy loads. This pack hits on an excellent combination of robust suspension, above-average padding, ergonomics, and a suite of great features. Notably, it includes one of our review team's favorite assortments of pockets.

The drawbacks of this pack mainly have to do with the unavoidable realities of any pack this size: it's the heaviest in our review (though not by much), and its size makes it challenging to find gear deep down if you haven't thought to keep whatever you are looking readily accessible. While the Xenith 105 is one of the best load hauling packs we have ever tested, the Gregory Baltoro 65 is right on its heels. In the end, they are both powerful load-hauling tools. But it edges out the Baltoro 65 for long trips where you just plain need a lot of stuff.

Why You Should Trust Us


Our lead backpack reviewers, Ian Nicholson, Adam Paashaus, and Ben Applebaum-Bauch, have tens of thousands of backpacking miles logged between them. Ian is a professional internationally licensed IFMGA/UIAGM mountain guide having spent over 3,000 days guiding in the Pacific Northwest, European Alps and beyond. He has guided more than 1,000 clients and helped them select and fit packs for their adventures. When not guiding or climbing, Ian works in an outdoor gear shop, keeping up-to-date on innovative pack technology. Adam, also a long-time guide and outdoor instructor, travels full time with his family and recently spent the month of September thru-hiking the Long Trail in Vermont with his wife and two girls (ages six and nine). When Adam isn't thru-hiking with his family you can be sure to find him trail running, rock climbing, planning the next trip or scouting the next place to call home. Ben began his outdoor career as a backpacking trip leader, guiding participants on multi-week adventures along the most rugged and remote portions of the Appalachian Trail in New England. He has since trained dozens of guides to do the same with over 1,000 participants while ensuring that they all have the appropriate, properly-fitted gear for their adventures. He has subsequently endeavored on thru-hikes of some of the iconic long trails of the U.S. including the Pacific Crest Trail, Long Trail, Colorado Trail, Oregon Coast Trail, and John Muir Trail.

We researched over forty of the top backpacking backpacks on the market and selected seventeen of the top contenders for hands-on testing. We loaded them up with a variety of gear and took to the trail on a series of adventures ranging from volcano climbing trips to alpine rock approaches and thru-hikes. We tested how each pack handles small and large loads and figured out maximum comfortable carrying capacities for each. We took advantage of different features, strapping and clipping gear on in various ways to get a sense of each model's versatility. As we walked, we took note of back panels, shoulder straps and waist belts, and how they felt against our bodies.

Analysis and Test Results


There are several factors to consider when shopping for a new backpacking backpack, whether it's going to be your first pack, you're upgrading from an older model, or you're simply adding to the quiver. The most important things to keep in mind are where and how are you going to use the pack. The packs we selected are models meant for your typical backcountry camping trips. Most of them are versatile enough for general mountaineering and, to a lesser extent, expeditions.

Nearly all the contenders we reviewed can also serve for travel, particularly for wear-your-suitcase worldwide adventures. Backpacking packs can be far more comfortable to use than a more traditional suitcase or duffel bag in rough terrain or areas with few paved roads. We directly compare the best and most popular backpacking packs, breaking down their pros and cons to find the right one for you.


Value


Backpacks can be pricey, but with the right pack, that investment can pay some serious dividends. If you have ever trekked up into the mountains with an ill-suited pack, there's no doubt you can appreciate the value that a quality model can have. We didn't just focus on the high-end, bank breaker models, but we also tested a range of excellent wallet-friendly designs such as the Osprey Volt 60; winner of our Best Buy Award. Also in this price range is the Deuter Air Contact Lite is a close second place for our best budget buy award. The Air Contact Lite gives you more volume and a heartier suspension when compaired to the Volt, but it is heavier and costs more. Our favorite pack, the Granite Gear Blaze 60 offers well-above-average performance at an average price.

Comfort is the most important factor when selecting your pack. You won't care about pocket design if your back hurts. Photo: Michael and John Yarnall Backpack testing on Eiley-Wiley Ridge with Luna Peak and the Northern Pickets in the background.

Suspension and Comfort


We cross-compared each models' shoulder straps with a focus on comfort, anatomical conformation, and support. We analyzed their shape, ergonomics, and the quality of their padding. We also studied each model's back panel and waist belt.

Adjusting the torso length on the Blaze 60 is intuitive and anyone can do it without a struggle.

The waist belt and shoulder straps are foundational factors to consider when picking a pack as they make the most significant contribution to a packs' comfort or lack thereof. This is evidenced in that the hips and shoulders are the most common trouble zones after (or in the middle of) a long day on the trail, especially if you are toting a monster load. To test the selected models we took them on multiple extended trips, loaded with weights in the twenty-five to the 55-pound range.

The Thule Versant's shoulder straps are narrower and slimmer than most. While not our favorite  they are only marginally less comfortable than other more comfort-focused models  even after hours of carrying heavier loads. This is likely due to their excellent ergonomics  breathability and comfortable materials.

While not our favorite, they are only marginally less comfortable than other more comfort-focused models, even after hours of carrying heavier loads. This is likely due to their excellent ergonomics, breathability and comfortable materials.

Hand-in-hand with comfort is a pack's suspension. The system of straps, stays, and it's frame controls how effectively the backpack will be supported on your skeletal structure and how well the frame will transfer the load from the pack body to the waist belt. We also noted how well each pack shifts the weight to the front of the shoulder straps rather than the top, so your shoulders don't get crushed.

As each person's body is different, we collected comfort experiences from a wide range of users, including OutdoorGearLab editors, friends, and our climbing and backpacking partners. We compiled well over 300 user days worth of data to give us a broad perspective on which packs satisfy our comfort standards across multiple body types.


After extensive testing with typical 25-45 lb loads, the ULA Catalyst and the Osprey Atmos 65 AG turned out to be incredibly comfortable, but all of our testers agree, the suspension on the Granite Gear Blaze 60 is incredibly strong, while the pack, weighing only 3lbs, is super light for the amount of weight it can actually carry.

The Osprey Atmos 65 AG provides a snug ride with its trampoline-style suspension, which spreads the load evenly across the body. We rarely got hot spots on our backs and hips, even after extended travel in warmer conditions. One reason for the lack of hotspots is the heavily-tapered padding in the straps and waist belt, which provide the thickest cushioning where you want it the most, like on top of your shoulders. At the same time, minimal padding zones reduce chafing.

The shoulder straps of the Aether are well articulated  nicely padded  and feature a pleasant face fabric. These features are more comfortable than average  and the pack is soft enough to wear shirtless or with only a tank top.

The Arc'Teryx Bora AR 63 comes with dreamy foam that is both soft and supportive. It's like a therapeutic mattress for your shoulders. Because of this conforming foam, the load is well-distributed across the padding.

On trips that require more than 45 pounds far fewer backpacks remain comfortable. In this photo Tester  Ian Nicholson is wearing one of his favorites for heavy loads  the Osprey Xenith 105.

At loads above 45 pounds, the Osprey Atmos 65 AG becomes less comfortable. The best performing contenders for big loads are the Gregory Baltoro 65, Granite Gear Blaze 60, Arc'teryx Bora AR 63, and the Osprey Xenith 105. These packs use high-quality foam that captures a useful balance of support and comfort. All the shoulder straps on these packs offer top-notch ergonomics and slightly stiffer than average padding. While this rigid padding is marginally less cush, it's what you want when you're schlepping a large load. Each of the models mentioned above offers subtle advantages that will help transfer that load and keep you moving towards camp in comfort. These include foam stiffness, shoulder strap shape, and waist belt shape, the combination of which lands them in the load-hauler category.

While we notice a bigger difference between the comfort level of waist belts than shoulder straps  that isn't to say that a good shoulder strap design isn't EXTREMELY important. All of our testers appreciate packs with ergonomic shapes like those on the Osprey Aether Pro  which are incredibly comfortable after hours on the trail.

Different designs are better suited to different body types. With that in mind, we noted a more significant difference between waist belts than between shoulder straps. We don't notice the distinctions with lighter weight loads of around 25-35 lbs, but once we bumped it up to 40-45 pounds, the differences between models stood out. Our favorite waist belts are on the Osprey Xenith 105, Aether Pro 70 and Arc'Teryx Bora AR 63. For the heaviest of loads (60+ lbs), we appreciate the Gregory Baltoro 65's robust and customizable lumbar pad, which makes a difference in providing much-needed support for carrying the extra weight.

A lot of people ask about the heat-moldable waist belt featured on the Osprey Aether Pro 70. After extensive side-by-side testing, we found little, if any difference between molding it in a convection oven or just breaking it in the old fashion way (AKA using it).

While the suspension is closely tied to comfort  they are fundamentally different. Comfort is how a pack feels against your body whereas suspension is how effectively a pack transfers load from the pack to your hips and protects your shoulders and spine from the weight of your pack.

The Gregory Baltoro 65, Osprey Aether Pro 70, and Osprey Xenith 105 all feature substantial suspensions with the Arc'Teryx Bora AR 63 taking the cake. These packs carry large loads well.

A robust suspension helps a pack feel solid on flat trails but really helps the pack move with us on difficult cross-country terrain  like when bushwhacking through tallus fields. Comparing packs in the North Cascades  WA.

While the Osprey Atmos 65 performs well when carrying loads below 40 pounds, it isn't great for loads above that point as its anti-gravity trampoline-style suspension feels mushy and less supportive under such a burden. The ULA Catalyst and the Granite Gear Blaze 60 both feature fairly robust suspensions and weigh only 3 pounds each — an impressive feat!

This is the Atmos 65's AG  or Anti-Gravity  frame. It's an example of a trampoline  or suspended  suspension. Your back presses against a mesh back panel  which is suspended over a more traditional frame. This tends to produce fewer hot spots since weight is distributed over a larger area. It also allows air to flow  making these packs cooler and less sweaty. Unfortunately  they don't handle loads over 45 pounds well. The suspension starts to collapse.

It also allows air to flow, making these packs cooler and less sweaty. Unfortunately, they don't handle loads over 45 pounds well. The suspension starts to collapse.

Trampoline or Suspended Suspension System


Trampoline-style or suspended suspension systems feature a mesh back panel that is tensioned (like a trampoline) over a more traditional frame single stay or "Y" shaped frame. These allow more air to flow, reducing back sweat. More importantly, they tend to produce fewer hot spots because the weight distributes evenly. This design is becoming increasingly common.

We like trampoline-style suspension systems for breathability and weight distribution. However, when it comes to massive loads, having the weight set off your back increases leverage and makes for a less comfortable carry.

On extended trips  you likely will have a lot of gear; a few features to stay organized can be nice  as long as they don't add too much weight. After a long day of backpacking pack testing and over 5 000ft of vertical gain  we were rewarded with an amazing camp and fantastic views of the Southern Pickets.

Features and Ease of Use


This metric evaluates how easy it is to pack and retrieve items from these backpacks paying particular attention to the design of the main compartment, pockets, lid, straps, and other unique goodies. Additionally, we compared the number and location of extra pockets and how useful our testers found them. We also carefully examined how helpful the lid (or brain) of the pack is at providing easy access to a handful of items and whether those items stayed organized. Lastly, we appraised the access points to the interior of the backpacking backpacks.

Having two straps for a sleeping pad or other oddly shaped items is a small but excellent feature to have. We particularly like how long the Osprey Atmos's straps are and find that they are able to fit pretty much any sleeping pad (something that can't be said about the majority of backpacking packs).

We particularly like how long the Osprey Atmos's straps are and find that they are able to fit pretty much any sleeping pad (something that can't be said about the majority of backpacking packs).

We looked at each pocket and asked ourselves: does this pocket make my life easier and keep me more organized, or is it just adding weight to the pack? We also looked at access points and evaluated whether they are useful for retrieving items or if they are just for show and impractical to zip shut when the pack is full.


We also broke down how useful any additional features are and evaluated them during real-world use in the field. We favor packs with a handful of straps for crampons, ice axes, sleeping pads, flip-flops, or other items because it adds to the pack's overall versatility. We give higher scores to models with better weather resistance, ice ax attachments, and easy to use waist belt buckles.

Comparing the buckles on two waist belts. The upper uses a redirected strap which is much easier to pull on  while the lower is the traditional "push and pull."

Overall Organizational Ability


For folks who like an assortment of compartments and pockets for organization, Granite Gear Blaze 60, and ULA Catalyst have handy pocket designs. These models offer a similar set-up and have our favorite overall organizational and pocket layout. All of these packs provide great hip belt pockets, big water bottle side pockets, and a stretchy mesh stuff-it pocket, excellent for drying out clothes or carrying oddly shaped items like fuel bottles, camp-shoes, or a frisbee.

The Gregory Zulu 55 and Gregory Baltoro 65 offer excellent gear access. These models all provide great options for folks who like a lot of organization or the ability to get inside quickly without having to take much out. The Osprey Xenith 105 offers decent access via a zippered side panel, but it's not nearly as good as the other three.

Our testers love the dual zippered lid pockets on the Baltoro 65. It's easily our review teams' favorite lid design. These pockets not only help users to stay organized but  because of their upward orientation  they are both easy to access and search through.

Top Lid Pocket


Almost every pack has a top lid with a zippered pocket (some folks call the lid the brain of the pack). This ubiquitous feature is one of the best places to store small items that require quick and easy access such as sunglasses, sunblock and bug spray. The majority of the models also have a separate smaller pocket on the underside of the lid, offering a secondary place to store small items that don't need to be accessed as frequently, like car keys.

Nice wide opening on the top lid  but not a whole lot is keeping stuff from falling out.

Our favorite top lid design is the Gregory Baltoro 65. Second place goes to the Arc'teryx Bora AR 63. Both feature lid-pockets with zippered access on the top of the pack rather than the more common zipper on the side. This arrangement makes it easier to locate items and makes them less likely to fall out while we search. The Gregory Baltoro 65 also has two lid pockets that are shaped to make searching easier.

The Osprey Aether 60 AG's lid boasts a relatively common design with a zipper on the side. The Aether is better than normal because the zipper wraps around slightly to each side  making it easier to search for small gear. But we don't like it quite as much as the Gregory or Arc'teryx models.

Most of the packs have zippers on the front or back of the lid which means that it's not as easy to get inside of them. However, not all side-zippered lid pockets are the same. The sizeable zippered lid pockets of the Osprey Atmos 65 AG, Osprey Aether AG 60, and the Osprey Xenith 105 are the next level. They have nearly the same volume as the Gregory Baltoro 65 and have a longer than average zipper that wraps slightly around the sides.

Pack Access


How you access the primary compartment is part of our Ease of Use metric and measures how easily we could grab a few items without unpacking the entire bag. The value placed on this metric depends on the user and the volume of the pack. However, as pack volume increases, access becomes of greater importance.

While ease of access is an important consideration, it is trumped by weight concerns. Don't select a pack solely for an elongated zippered access panel, especially if you will rarely use it, but will none-the-less pay a weight penalty for having it. Zippers are heavy! Moreover, as a general rule, side access panels are a real pain to close back up when a pack is full.

Weight Penalty — All features come with a weight penalty. Consider your priorities before saying "I want lots of access". We hear that often only to witness folks go several trips between using their side access panel. The exception is when you're traveling in the front country, where access is more important, and you won't be hauling your pack for quite as long.

The Baltoro has one of the best access points in our review. Not only is it the largest  but it is also well-designed and allows us access to a large portion of the pack. It offers a big enough opening that we can take items out (like a tent) without having to unpack our entire pack.

All the backpacking backpacks in our review are top-loading, and many have a sleeping bag compartment with separate bottom access zipper. These openings enable access to a part of the pack that is hard to get at from the top.

Hip belt pockets are surprisingly nice once you step out onto the trail. They provide easy access to a camera  snacks  etc. while barely forcing you to break stride. The Aether 60 AG's zippered pockets shown here are among our favorite in the review.

Hip belt pockets


These days, a pack with a good hip belt is essential. We especially love the Granite Gear Blaze 60, and the ULA Catalyst models hip belt pockets for their unrivaled size and ease of access. It's also worth noting that the Gregory Baltoro 65 features a single weather-resistant pocket, which is particularly helpful for folks who want their smartphone close-at-hand for taking photos. This weather-resistant accessory is in addition to a secondary mesh zippered pocket. The The North Face Griffin 65 has stretchy hip belt pockets but they are on the small side and phones don't work well. However they are fine for stuffing snacks that can form around the contours of the waist belt.

This pack had excellent hip belt pockets. Plenty large for a large phone  small camera  tons of snacks or a map and compass.

Weather-Resistance


All of the models are reasonably weather-resistant, but the Arc'teryx Bora AR 63 stands out. It consistently kept our gear drier during spring hikes in Washington's Olympic rainforest and garden hose tests. This pack uses Arc'teryx's AC² fabric, which is exceptionally weather-resistant, bordering on waterproof. The Arc'teryx models even have taped seams near exposed areas like the back kangaroo-style pocket, which also sports a watertight zipper, because this location will likely see the most moisture while on the move.

The Baltoro 65 comes with a fairly functional hydration pack that doubles as a bladder sleeve inside the pack. Here we show a shell jacket and 70 oz Platypus bladder for size reference. This separate pack is designed to be taken on a summit push or day-hike from camp but is just as suitable for use around town.

Hydration


Almost all of the packs in this review have a location to store a hydration bladder where it will remain upright. The models with this feature should work with just about any brand's 2-3 liter hydration bladder.

Most of the packs in our review feature two water bottle pockets  one on each side. A handful of models from Osprey and Gregory tweak the common design to point the water bottle forward  making it much easier to access and stow water bottles. Most of these packs also have another opening near the top of this pocket to securely hold oblong shaped items outside the pack  like tent poles or a snow picket.

Rather than use the same brand bladder as the pack, we recommend reading our Hydration Bladder Review and picking the best reservoir for your needs and budget. One super cool bonus feature among packs we tested was that the Gregory Baltoro 65 comes with a removable hydration sleeve that doubles as a relatively functional hydration pack.

Weight is obviously important in any person-power activity and your gear and pack weight add up. That's why you should be wary of opting for a bigger volume than you need because it can be surprisingly hard to NOT fill your pack with unnecessary items.

Pack Weight


The lightest packs in our review, by a pretty significant margin, are the Granite Gear Blaze 60 and ULA Catalyst. Both check-in at around three pounds and thus approach the line between a backpacking pack and an ultra-light minimalist pack. The big difference here is that these models are more comfortable for people who don't have their pack weight down below 20 pounds.

The Granite Gear Blaze 60 and ULA Catalyst are excellent options for folks who want to go super light but want a comfortable and supportive pack with a frame and more robust padding for certain trips when you need more weight or after leaving town with a fresh resupply. Because of their light-weight and great weight carrying capacity, these packs are popular for long trail thru-hikers and section hikers alike.

Every model strikes a balance between weight and comfort. Having both is hard. The Osprey Aether Pro 70 fits into a similar much-needed niche. This pack is sub-4 pounds but still has one of the most robust suspensions systems we tested. It's also one of the most comfortable models in our review, thanks to its top-tier foam, heavily articulated shoulder straps, and top-notch feeling face fabrics.

You pack can truly make-or-break even the most well-planned backcountry adventure. If your rain jacket is a little to big or small it is only a small inconvenience. If your pack doesn't fit well it will make your shoulders  hips  and back sore  possibly to the point of wrecking your trip.

Adjustability and Fit


To judge each backpack's adjustability and fit, we consider its overall ergonomics in addition to how adjustable each model is. We also look at the range of torso lengths available. More sizes mean it could work for a wider range of users.


Mix and Match Sizing — A handful of pack manufacturers will let you swap out shoulder straps and waist belts sizes to customize your fit. For example, you may want a medium frame and a small waist belt. If this would be helpful for your body type, it's worth seeking out a pack from one of these manufacturers, like Gregory or ULA.

The Volt and the Aircontact Lite 65+10 have the most vertical adjustment of any model in our review. The huge vertical adjustment range helps dial in your fit and makes it an excellent option for younger backpackers who are still growing.

The Deuter Aircontact Lite 65 + 10 and the Osprey Volt 60 have by far the most vertical adjustment of any pack in our review. Both of these models can move their yokes (shoulder straps) up or down nearly 10 inches. Not only does this help fit a wide range of people and let it genuinely tailor to its wearer, but it also makes them an excellent choice for quickly growing children, teenagers, and camp or youth program uses.

We really liked the unique "GridLock" system on Arc'teryx's Bora packs. It allows you to adjust the shoulder straps both vertically and horizontally. It looks like flimsy plastic  but in our experience  it's an absolutely bomber design. The shoulder strap never came prematurely undone.

When it comes to straight-up vertical adjustment, the Osprey Volt 60 and Deuter Aircontact Lite 65 + 10 have the advantage. However, when it comes to tailor-like fitting, the adjustment options of the Arc'teryx Bora AR 63 reign supreme. While it doesn't have as much vertical adjustment range, we love that we can adjust the shoulder straps side to side (width-wise), as well as up and down. The Gregory Baltoro 65, Osprey Atmos 65 AG, Osprey Xenith 105, and Osprey Aether 70 also have a respectable amount of adjustment. They feature approximately four inches of vertical adjustment and are available in many sizes. We also took into account each pack's overall ergonomics in our fit metric.

Most packs are available in multiple frame sizes and you can further adjust all the models we tested to fine-tune the fit. The Xenith shown here features the most common adjustment style: the shoulder straps are attached to a Velcro-covered flap that can be slid up or down behind the back panel. This gives the user roughly 4 inches of adjustment. We gave extra points to packs with adjustable girth waist belts or the ability to adjust the shoulder straps both vertically and horizontally.

Rain Covers


We have mixed feelings about rain covers. They are a useful addition — to an extent. In our experience, if the rain is falling for multiple days at a time, unless you have packed your gear in dry bags or lined your pack with a trash compactor bag, your stuff is going to get wet. A pack cover can only do so much to mitigate this reality, but it keeps excess water from soaking into the fabrics. The backpacks in this review are not waterproof; however, the Arc'Teryx Bora AR 63 comes pretty darn close. It's worth noting that many of the packs in this review include a rain cover, including the Gregory Baltoro 65, Osprey Rook 65, Osprey Volt 60, and REI Traverse 70.

The rain cover included with the Baltoro 65. While small  we appreciated this feature  which could be left behind when the weather allowed.

Conclusion


Though traveling from points A to B on a backcountry trip is conceptually simple enough, choosing the right backpack that will get you and all of your gear to the end in the best shape possible is a bit trickier. We hope that our testing and reviews will help you narrow down your options.

In summary: first focus on the duration of trips you typically take. Come up with 2 to 3 features that you'd like your pack to have and prioritize specific designs like cushy shoulder straps, perfect pocket or feature set or a sub-4-pound weight.
