The Best Backpacking Backpacks of 2017

The Best backpacking pack review
There are hundreds of backpacking backpacks from the ultralight to the ultra comfy. We researched 65 packs and bought the 12 best for 210 hours of side-by-side tests in the mountains of Patagonia and the Pacific Northwest. Today's backpacks are more feature-rich than ever, but it's hard to distinguish what's useful and what just adds more weight. We'll find you the right model for a 2-8 day trip whether you're a minimalist or want the feeling of backcountry luxury every time you clip your hip belt. Since no pack fits everyone perfectly, our mountain-guide-led testing team got fit feedback from friends and clients to more accurately score comfort and suspension. Read on to pick your perfect pack.

Our 2017 review update includes new award winners, charts, and graphs. It's easier to see how each pack excelled or flailed in each metric. While the Arc'teryx continues its reign in the scores, many new award contenders emerged, especially for value and lightweight. The packs keep getting better and the competition tighter.

Best Overall Backpack


Arc'teryx Altra 65


Arc'teryx Altra 65 Editors' Choice Award

$380.00
at Backcountry

Very supportive
Awesome pivoting waist belt
Very comfortable
Innovative and effective adjustment system
Best lid pockets
Easily some of the best features of any pack in our review
Average weight
Expensive
The Altra 65 has won our Editor's Choice award more than any other pack. In 2017, it's again on top. Even with heavier (50+ lbs) loads, it's still comfortable and surprisingly light. It's unique pivoting waist belt transferred the pack's weight comfortably to our hips. The Altra has some of the test teams' favorite features like a dual-zippered lid (that was the easiest to search for lost items in) and a giant "U" shaped access zipper running around the entire front side of the pack, as well as an enormous zippered kangaroo pocket. It does have a few downsides, mainly that at $475, it's $120+ more than any other pack in our review. If you don't need its load hauling prowess (if your loads are regularly below 40 lbs), then you could get away with a lighter pack that is also less expensive. If you've made it this far and you're going to spend $475, it will last for a while, and we'll vouch for it. We used the older, less durable version over 120 days (including six Denali trips) and were impressed with its longevity; the newer version is even tougher and more water-resistant. And if you are looking for a bigger size, Arc'teryx makes the Altra in the Arc'teryx Altra 75 and the monster Arc'teryx Altra 85.

Best Bang for the Buck


Osprey Volt 75


Osprey Volt 75 Best Buy Award

$199.99
at Amazon

Great price
Fits a broad range of people
Simple design
Not as supportive for super heavy (50+ lb) loads
The Osprey Volt 75 combines solid comfort and performance with excellent value. The $200 Volt 75, or the identical, but slightly smaller $180 Volt 60, scored fairly high in most categories and scored better overall than several much more expensive packs. The Osprey Volt 75 appeals especially to people who appreciate its simplicity: not tons of extra pockets or pouches, just the essentials and a slightly above average frame, padding and ergonomics. While the Volt 75 is not feature-heavy, it does have all the key features that backpackers care about the most, like a lid pocket, dual entry water bottle pockets, stretchy beaver tail pocket and a lower zippered access point (AKA sleeping bag compartment), among other things. What our testers really noticed was that the Volt has better, more ergonomic shoulder straps, nicer foam, and better-feeling face materials than most other packs in its price range. If you're looking for something a little smaller, check out the Volt 60.

Top Pick for Shorter Trips


Osprey Atmos 65 AG


Osprey Atmos 65 AG Top Pick Award

$251.99
at Amazon

Very comfortable
Packed full of features
Lots of awesome pockets offering excellent organization
Awesome ventilation
Lighter than average
Sweet adjustable hip belt
Not as supportive for super heavy (50+ lb) loads
Snow can get inside of the back panel
The Osprey Atmos 65 AG loses the Editors' Choice title this year, but it remains a Top Pick for short excursions and comfort. It's easily one of the best all-around backpacking packs because it's full of functional features, is comfortable, and ventilates fantastically, all at a lighter than average 4 lbs 6 oz. However, what edged it out for the best all-around backpacking pack is it just doesn't handle heavier loads (greater than 45 pounds) as well as competitors. If you pack on the lighter side or don't embark on extended trips as often, this pack is one of the best. What sets the Atmos apart is its luxurious AG suspension that spreads the load out evenly across your body and makes your pack seem lighter than it is. For trips where we were carrying less than 40 lbs, this was hands down the most comfortable pack in our review for the majority of our testers. Another big advantage is the fit, ergonomics, and adjustability of the Atmos from the frame to the waist belt. Our testers raved about it's refined design: every additional pocket is in the right place, is the right size, with few features our testers claimed to be useless. The only downfall: the Anti-Gravity suspension doesn't carry super heavy loads as comfortably as some of our other Top Picks, and it can fill with snow during winter or mountaineering objectives. Want the smaller and lighter version of this pack? Check out the Atmos 50 AG.

Top Pick for Comfort and Features


Gregory Baltoro 65


Baltoro 65 Top Pick Award

$269.94
at Oregon Mountain Community

Super comfortable
Carries heavier loads among the best in the review
Dual zippered lid pockets are awesome
"U" shaped opening provides easy access
Slightly heavier than average
Supportive foam can feel stiff initially
The new and improved Gregory Baltoro 65 is just as comfortable as ever and offers improved features and usability while somehow weighing eight ounces less than the previous model. The Baltoro remains the straight-up best pack in our review for carrying monster loads (more than 60 lbs) and offers a plethora of features. It's a little heavier than other models; at 5 lbs 3 oz, but not much heavier, especially if you need to carry a significant amount of weight or access is super important to you. It will last (nearly) forever and gives you a ton of features for your money. The Baltoro is also available in larger sizes, like the Gregory Baltoro 75 and the Gregory Baltoro 85. Gregory has also teamed up with Goal Zero with the Gregory Baltoro 75 GZ to provide charging capabilities.

Top Pick for Extended Trips


Osprey Xenith 75


Xenith 70 Top Pick Award

$254.13
at Amazon

Super comfortable
Carries heavier loads among the best in the review
Superb external twin zippered pockets
Functional and easy to use stretch mesh zippered pockets
Difficult to search for items in lid pockets
Lumbar pack lid rarely useful
If you frequent trips of 5-20 days or trips that require you to carry a lot of gear, then the Xenith is the pack for you. It comes in 75L, 85L, and 105L options, and the Xenith is tester Ian Nicholson's favorite Denali Pack (which is 22 days of arctic cold weather and HEAVY LOADS). The Xenith series also ranks as a favorite among many NOLS instructors for extended adventures. We think it just hits the sweet spot of a robust suspension and above average padding and ergonomics while offering sweet features and a nice assortment of pockets for extended trips. It remains relatively lightweight for a pack that carries so fantastically. While the Xenith was one of the best load hauling packs we have ever tested, it was a toss up as to which pack could carry monster loads better: the Baltoro or the Xenith. In the end, they both proved to be awesome packs; the only difference between the two came down to slight personal preferences. The Xenith is also available in the Osprey Xenith 88 and the spacious Osprey Xenith 105 to keep you supplied on your longest trips.

Top Pick for Best Lightweight


Osprey Exos 58


Osprey Exos 58 Top Pick Award

$220.00
at Backcountry

Lightest pack in the review
One of the lightest framed packs available
Comfortable for loads under 40 lbs
Great pockets and features
Average durability
Not a ton of extra features
Not very adjustable
The Osprey Exos 58 was the lightest pack in this review by over a pound, but remained comfortable for moderate sub 40-pound loads. This is what's unique about the Exos; it almost blurs the line between traditional backpacking packs and ultralight packs. It's almost as light as many commonly frameless minimalist ultra-lightweight packs (being only 0.5-1 lbs heavier than most), but still has the essential features you'd expect in a traditional backpacking pack (including a frame). It's a great stepping stone for people who want to get into "ultralight" backpacking but can't get their load down to the 20-30 lbs necessary to make a sub 2-pound frameless pack comfortable. Or, it's for people who already pack on the light end, but want a little more suspension, comfort, and features that most frameless packs don't provide. If you like the idea of a lighter weight pack, but want a few more features and a slightly more substantial frame, consider the The North Face Banchee 65 or REI Flash 65, both 3 lb 10 oz.

Analysis and Test Results


There are many factors to take into consideration when purchasing pack for backpacking. We took almost a dozen of the top models  pitted them head-to-head  and reported our findings here. Photo: Backpack testing in the Oregon Cascades.

There is a lot to consider when selecting the right backpacking backpack, whether it's your first bag or you're just adding to the quiver. In this review, we compared the best and most popular men's backpacking backpacks. These packs are the type of packs that most people will be drawn toward and will use for day-in and day-out backpacking. While the packs we chose to review could be used for travel, such as "backpacking" through Europe or Southeast Asia, and most are versatile enough for some general mountaineering applications, these packs aren't necessarily geared specifically for those activities.

Picking the Right Volume


We chose to review 55-75 liter packs; this is the volume most people will choose to carry on overnight trips from two to eight days, which is the length of excursion that makes up the bulk of most backpackers trips. While a lot depends on experience, comfort level, weather considerations, and objectives, most backpackers will have a little extra room in their 55-75L pack for 2-3 night trips; everything will fit just right for those 3-5 night trips and will work, but might be a little tight for 5-10 night trips.

There is a lot to consider when buying a backpacking backpack  from how long you think you'll regularly go out for  what type of trips you might embark on  to how experienced you are. In the review below we try to break down the most important factors and considerations when purchasing a backpacking pack. Photo: testing pack comfort with the Osprey Volt 75 and the Deuter near Mt. Baker  WA.

Baker, WA.

If you tend to go on 2-3 night trips, this review is still highly relevant, as most of these pack models are available in slightly different capacities. Most models will often come in both larger and smaller sizes. For example, most pack manufacturers make an extremely similar pack in the 65-75L range with other similar 50, 70 and 85-liter sizes also being common. We have also tested and used many of the larger versions of these packs and find that different volume sized models perform very similarly and in most cases, the overall design, frame, shoulder straps and waist belts are the same. If you read our review of the Arc'teryx Altra 65, you can assume that the Altra 75 will perform in about the same capacity as the 65.

The volume of backpacking backpack you purchase should be based on the number of days you tend to go out for  not how long you hope to go out for. These numbers are for average backpackers and depending on your experience  weather factors  and objectives  it is possible to get away with a much smaller pack.

These numbers are for average backpackers and depending on your experience, weather factors, and objectives, it is possible to get away with a much smaller pack.

What Capacity Pack Should I Buy?


The question "What volume pack should I buy?" is mostly answered with another pair of questions: "How long do you typically go out for?" and "How light do you pack?". While the latter of these two questions is less quantifiable, we can give you some solid recommendations for what the majority of people use as a good place to start. 40-60L is a good volume for most people for 1-5 nights. For 2-7 night trips, we would recommend 50-75L packs. Lastly, for most people taking trips one week or longer, we would recommend 60-85L packs. We focused our review on 60-70L packs because those are the most popular overall volume and they tend to suit the most people for their needs.

What volume pack you should decide to purchase has a lot to do with how long you plan to go out for  and specifically what activities you hope to use it for. Here tester Ian Nicholson opted for a slightly bigger pack to accommodate glacier mountaineering gear  while testing backpacking backpacks and instructing in the North Cascades.

Pack Weight


Gone are the days of the eight pound behemoths that were the standard 25 years ago. Today, even full featured backpacking packs are much more comfortable than their heavier ancestors and often weigh in at a little over half of that. Even the heaviest pack in our review, the Deuter Air Contact 65 + 10, tips the scales at a little over six pounds, with most of the packs in our review weighing between three and a half and just over five pounds, with a few lighter options, like the 2 lb 8 oz Osprey Exos 58 or even some more heavily featured models like The North Face Banchee 65 or the REI Flash 65, weighing in at 3 lbs 10 oz.

While we give recommendations on what volume packs work for the majority of people for a given length trip  everyone is a little different. Here tester Ian Nicholson baking pizza from scratch deep in the backcountry.

A Note on Pack Weight


Everyone always wants to pack lighter, but trying to save a bunch of weight by purchasing say, a sub-two-pound frameless pack, while still trying to carry all of the stuff you would typically carry is not a good way to go about it. It's best to lighten your overall kit first by focusing on what you need to bring and leaving behind things you don't, as well as lightening a few key pieces of gear if you haven't already (like shelter, sleeping bag, and your clothing).

Once your kit (including food) is below approximately 25-30 lbs, then it's okay to start looking at a "ultra-light" frameless sub 1.5-2 pound pack. If you have a 10+ year old burly backpacking backpack, that likely weighs around seven or eight pounds, then its completely okay to buy a newer 3-6 pound pack that is obviously lighter, MUCH more comfortable, and outfitted with nicer features.

Some companies use specific proprietary tools to assist in pack fitting. While nice  measuring tape still works just fine.

Pack Fitting 101


For far more in depth tips, recommendations and advice on how to properly fit a backpacking backpack, be sure to check out our buying advice article. There are a few good fundamentals you should make yourself aware of before purchasing a pack. The first one is frame size; just because you are tall doesn't necessarily mean you should be in a longer or taller size pack. Most pack manufacturers give accurate recommendations as to which torso length should be fit with a corresponding size. How do you measure your frame size, you might ask? Measure from your C7 vertebrae (the highest vertebrae that pops up when you lean forward) down to the "pelvic girdle." The pelvic girdle is most easily found if the person being measured puts their hands on their hip bones (Iliac crest), with their thumbs pointing toward their backs; the line between their thumbs is the bottom end of the measurement.

The second fundamental is where the waist belt should sit on the user. While a lot of people might have an instinctual feel as to this location, many do not. Ideally, the top of the wearer's hips should fall anywhere from in line with the top of the waist belt, to anywhere around half way down. The third fundamental is that that once the straps are adjusted, you should ideally see the shoulder straps contouring up and over the wearer's shoulders with very little space or gaps. The load lifters (the upper straps) should be pulling the shoulder straps up at around 45 degrees, though anywhere from 35-60 degrees is acceptable.

Comfort


For our comfort category, we compared how comfortable and supportive each pack's frame, shoulder straps and hip belt were by field testing each pack for hours… and days at a time. We compared these packs with standard 30-45 lb loads that most backpackers might carry for week-long trips, as well as a "load hauler" type loads where we compared each pack with 55-65 lbs for a little longer than our hips and shoulders would have liked.


We paid extra attention to how the waist belt and shoulder straps felt on each pack after wearing them for long days and with heavy loads. We took into account other feedback from OutdoorGearLab Editors, their friends, and climbing partners (thanks guys) and tested these packs in excess of three hundred days to help give us a broader and less single body type perspective when choosing the most comfortable pack.

After extensive testing with normal 30-40 lb loads, the new Osprey Atmos 65 AG scored at the top for comfort. Its trampoline style suspension spreads the load evenly. Our testers rarely got hot spots on their backs nor their hips, even after extended cross country travel in warmer conditions. For heavier loads, the Arc'teryx Altra 65, Gregory Baltoro 65 and the Osprey Xenith 75 tied for the most comfortable product in this category. All three of these packs use high-quality foam that achieves a nice balance of support and comfort. Our testers thought that the Altra's pivoting waist belt was the most comfortable in the review and did the best job of transferring weight from our pack to our hips. However, while the Altra's shoulder straps were good, after extended side-by-side testing, they just didn't feel as comfortable as the Xenith 75 or the Baltoro 65. The thinness and ergonomics just couldn't match that of the overall design of the Xenith and Baltoro, which we thought used nicer foam and better face fabric while offering slightly better articulation and an overall superior design that our testers liked better.

Not far behind the Xenith 75 and the Baltoro was the Gregory Contour 60, The North Face Banchee 65, and Osprey Aether 60 and 70L. While these models weren't quite as comfortable as the two packs listed above, they weren't very far behind either. For medium and lighter weight loads of around 30-40 lbs, we noticed significantly less of a difference between packs, but once we crested 40 pounds, additional weight was exponentially challenging for packs to handle.


The fabric Osprey uses on the inside of the shoulder straps of the Osprey Xenith 75 and Osprey Aether 70 was incredible, while the feeling of the Atmos 65 AG was our favorite on bare skin; the shape and articulation of these packs was second to none. A lot of people ask about the heat moldable waist belt featured on the Aether among other models of Osprey packs. After extensive testing, there is little, if any difference, between molding it in a convection oven, or just breaking it in the old fashion way (AKA using it). After side-by-side testing a molded waist belt and one that had been used for a three-day trip, there was almost no difference.

The Aircontact's shoulder straps and waist belt were very comfortable, but not quite as comfortable as the Xenith 75 and Baltoro 65. The Air Contact's padding was noticeably bulkier and hotter, and the shoulder straps were not shaped quite as nice for most of our testers. If you feel like you carry more than 40-45 lbs on a regular basis, we would recommend the Xenith 75, Altra 65, or the Baltoro 65. If you rarely carry 40 or more pounds, we loved how the Osprey Atmos 65 AG and The North Face Banchee 65 felt as long as we didn't overload them. These packs felt good up to 40 lbs; above 50 lbs, the Xenith and Baltoro were superior.

Suspension


The suspension category encompasses how well the frame transferred the load from the pack into the waist belt and to a lesser extent, onto our shoulder straps. The suspension is obviously tied in with a pack's overall comfort, but we specified unique criteria for each category. In addition, we compared the foam used and the articulation and how well the packs felt against our backs.


The Gregory Baltoro 65, Osprey Xenith and Arc'teryx Altra all performed fantastically, while the Xenith and the Baltoro just barely edged out the Altra and the Contour because of how nicely the frame transferred the load to the waist belt and our hips. With these two packs, very heavy loads were noticeably not as bad to carry and were both our Top Picks for extended trips and monster loads. That said, we did like how supportive and comfortable the foam on the Altra and the Aether were. The Osprey Atmos 65 AG, while super comfortable when carrying loads below 40 pounds, wasn't that awesome for loads above that when its Anti-Gravity trampoline-style suspension would feel mushy, less supportive, and just straight up did not feel as nice. The Deuter Air Contact was just a hair behind the Baltoro; it featured thick and comfortable padding and a supportive frame — some testers just thought it felt a little bulky.

Comfort not only included how well the pack felt on even ground and nice trails  but also how the pack moved with us on difficult cross-country terrain  like bush whacking and log crossings. Comparing packs in the North Cascades  WA.

Trampoline or Suspended Suspension System
Trampoline-style or suspended suspension systems use a mesh back panel over a more traditional frame. The advantages of this type of frame are that it allows more air to ventilate, making these backpacks cooler and less sweaty and more importantly, they tend to produce less hot spots on the users because the weight is spread out or "suspended" over a larger area of the wearer. More and more packs are using a similar design at least on the back panel portion of a pack. Our testers like the trampoline style suspension because of the aforementioned reasons; however, when it comes to massive loads, having the weight closer to your back and not having a gap will be more much comfortable. For example, the Gregory Baltoro 65 doesn't feature a true trampoline suspension system, but that's one reason it carries such massive loads so effectively. With all suspension style systems there comes a weight limit where the suspended mesh is pressed so tightly against the wearer that it either bottoms out or just causes a hot spot. The ventilation area that's so wonderful in summer can fill with snow during mountaineering or wintertime trips, making the pack much less pleasant to wear.

The AG or "Anti-Gravity" frame of the Osprey Atmos 65 AG pack. Frames like this one are often referred to as a trampoline suspension  or suspended suspension systems. The idea is that instead of having your back right up against the pack  your back is against a mesh back panel that is suspended over a more traditional frame. The advantage of this type of frame is that they tend to produce less hot spots on the user because the weight is suspended over a larger area. It also allows more air to ventilate  making these backpacks cooler and less sweaty. Their only disadvantage: they don't handle super heavy (50+ pounds) as well before they start to feel mushy and the suspension sort of half collapses.

Ease of Use


Our ease of use category includes how easy a given backpack was to pack and an examination of the design of the main compartment and additional pockets. In regards to pockets, we compared the number and location of additional pockets, how useful the lid (or brain) of the pack was, and how easy it was to access the main compartment of the backpack. For each pocket we asked ourselves, "Did that pocket make my life easier, or is it not that useful and just adding weight to the pack?". We also looked at access points and evaluated whether they were truly useful or just for show.


For the evaluation category, "Ease of Packing" we broke down the level of usefulness of each feature and evaluated them during real world use in the field. Our testers feel that if a pocket or access point didn't help, it was only adding weight. Lastly, we favored packs with a handful of straps for crampons, ice axes, sleeping pads or other items because we felt it added to the pack's overall versatility.

After a long day of backpacking pack testing and over 5 000ft of vertical  we are rewarded with an amazing camp  with fantastic views of the Southern Pickets.

Overall Organizational Ability
For folks who like a lot of compartments and pockets for organization, the Osprey Atmos 65 AG, Gregory Baltoro 65, Osprey Xenith 75, and The North Face Banchee 65 have by far the best and most usable pockets, while the Arc'teryx Altra 65 and Baltoro had the best access of any pack in our review. These packs provide great options for folks who really like a lot of organization or the ability to get inside their pack easily without having to take much out.
Likely our favorite overall feature for use-ability of The North Face Banchee 65 was its oversized dual-zippered pockets. These were great for water bottles  water filters  snacks  a light jacket  or simply anything else we wanted easily accessible.

Our favorite collection of pockets came in the Baltoro 65, which is on the heavier side of packs in our review at 5 lbs 3 oz, and the Banchee 65, one of the lighter packs in our review at 3 lbs 10 oz (around a pound lighter than average). The Deuter Air Contact has nearly as many pockets as either of the packs above, but we felt that they weren't as useful and neither were super easy to access. It's worth noting that the REI Flash 65 had nearly as many usable pockets and close to as many access featuring a "J" shaped opening; the cost is also only $200.

There aren't a lot of universal features that every pack has, but one thing that nearly every pack sports is a zippered top lid pocket (some folks call the lid the "brain" of the pack). This exceptionally common feature is one of the best places to store small items that the users might want, like sunglasses, sunblock and bug spray, among other things wanted close at hand. Many packs featured a separate smaller pocket on the underside of the lid, offering a secondary place to store small items. Our testers liked this feature, as it's a great place to put those items you want access to, but don't need as frequently.

Of all the packs we tested, our favorite top lid pockets belonged to the Arc'terx Altra 65 and Gregory Baltoro 65. They were the most usable. Both featured two pockets on the very top of the pack that made finding items easier and said items were also less likely to fall out while we rooted around. The rest of the packs had zippers on the front or back of the pack. None of these packs were as easy to get into as the Altra and the Baltoro, but not all are created equal. The large zippered lid pockets of the Atmos 65 AG and the Banchee 65 the next top scorers. They had nearly the same volume as the Altra and had a longer than average zipper that made access good, but not as great as the Altra 65).

Our testers loved the dual zippered lid pockets on the Gregory Baltoro 65. These pockets not only helped users stay more organized  but because of their upward orientation they were both easy to access and search through.

Pack Access
Pack access is part of our "Ease of Use" category and refers to how easily we could access certain larger items without having to unpack the whole pack. While access is nice, its level of importance depends on the user. Ease of access is an especially useful feature for folks using their backpack for travel, where they might otherwise use a suitcase or a duffel bag, to go "backpacking" through certain regions. Everyone wants more access, but zippers add weight and aren't always essential. It's a balance. Consider your priorities before just saying "I want more access." Is the increased weight of zippers worth it?
The Altra 65 features a giant "U" shaped zipper that extends around the perimeter of the backside of the pack. This was great for accessing any items buried deep and made packing up on multi-day trips easier and more efficient; because of these features  this is a fantastic travel pack for "backpacking trips" through places like Southeast Asia or Europe. The only downside is that when it's really full it takes a little more effort (AKA kneeling) to get the zipper closed.

All the packs we tested were top loading, and many had side access zippers, sleeping bag compartments, or entire panels that opened to allow access. Among all the packs we tested, we loved the Arc'teryx Altra and Gregory Baltoro the most for its huge "U" shaped opening that travels nearly the entire length of the back of the pack. It opened almost as large as a suitcase and makes an excellent pack for anyone "backpacking" through Europe, Southeast Asia, or anywhere else where access is the most important. The REI Flash 65, with its "J" shaped zipper, had superb access and above average for our review, but not quite as good as either of these two packs.

Extra Features
While not a must have, most of our backpacking testers appreciated having at least one zippered pocket on the hip belt that was big enough for a small point-and-shoot camera or a handful of snacks like gels, cliff bars, or a small bag of nuts. The North Face Banchee 65, along with the Osprey Volt 75, Xenith 75, and Atmos 65 AG all had some of our favorite hip belt pockets in the review.

While hip belt pockets are hardly a mandatory feature of a backpacking pack  most of our testers agree that its nice to have one that's big enough to fit either some snacks or a point-and-shoot camera.

Hydration
All the packs in this review have a place for a hydration bladder and just about any brand and model will fit in any backpack hydration sleeve. 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 the Gregory Baltoro came with a removable and fairly functional hydration pack that doubled as its hydration sleeve when used inside the pack.

Gregory Baltoro 65 comes with a fairly functional hydration pack that doubled as the bladder sleeve/holder when used inside the pack. A shell jacket and 70 ounce Platypus bladder for size reference.

One of the new features on the latest version of the Altra 65 is twin zippered "water bottle pockets" compared with open mesh ones. Our test team enjoyed the upgrade not only because bottles were easy to retrieve with the pack on  but for folks who mostly use a hydration bladder  these pockets could be used for other items wanted easily accessible.

Pack Weight


The lightest pack in our review was the Osprey Exos 58. At 2 lbs 8 ounces, it straddles the line between a backpacking pack and an ultra-light minimalist pack.


For a lighter but still rugged, and more featured pack, we like The North Face Banchee 65 or the REI Flash 65 (both 3 lbs 10 oz) and would certainly consider the Osprey Volt 75 (3 lbs 12 oz). They all hit a nice balance of being lightweight, but still comfortable and fairly full featured.
The Exos 58 is a surprisingly comfortable pack  especially considering its 2.5 pound weight. We thought it was fantastic to 30 pounds  and decent to 40 lbs  but we wouldn't want to carry much more than that.

Among the full-featured packs, the Osprey Atmos 65 AG (4 lbs 6 oz), Osprey Aether 60 (4 lbs 11 ounces) and the Arc'teryx Altra 65 (4 lbs 13 oz) remain lighter than average and give up very little in the way of comfort, load hauling ability, and features.

Proper pack fit is essential to making any pack feel good. OutdoorGearLab Friend Mark M. putting in his two cents while wearing a Mountain Hardwear South Col on the Northside of Mt. Baker

Adjustability and Fit


A pack's overall ergonomics, the more adjustable a pack is, and the more sizes it is offered in typically translates to a better fitting pack. Check out the chart below to see how each pack ranked in the adjustability metric.


A handful of pack manufacturers will swap out shoulder straps and waist belts for different sizes (for example, if you want a medium frame and a small waist belt), something that many stores and websites offer for free. The Deuter Air Contact and the Osprey Volt 75 has the most vertical adjustability for the yoke's (shoulder straps) positioning, not only helping it to fit a wide range of people, but also making them a good choice for quickly growing children. Despite this feature, our testers didn't think the either pack had the best overall fit.

Our testers did really like the adjustment of the Arc'teryx Altra. While it didn't have quite as much range, we loved how you could adjust the shoulder straps independently side to side (width-wise), as well as up and down. The North Face Banchee 65, Gregory Baltoro 65, Osprey Atmos, Xenith, and Osprey Aether 70 all had a respectable amount of adjustment. Our testers greatly appreciated each of the packs' overall ergonomics and gave all of these packs high scores in the "fit" metric.
The Osprey Aether 70 offers around 4" of vertical torso length adjustment by using a velcro flap to attach the shoulder strap that can be slid up or down on the inside of the back panel to adjust the length. This simple design is easy to fine-tune and is super reliable. We have never experienced the pack's shoulder straps slip or slide out of place at any time.

Rain Covers


None of these backpacks are waterproof. Using a trash compactor bag or garbage bag will get you through in a pinch. But if you are planning on a lot of time in the rain, consider a pack cover designed and fitted for your pack.

Here are a few options:
