The 6 Best Backpacking Backpacks of 2025

The Best Backpacking Packs for Men

Best Overall Backpacking Backpack

Granite Gear Blaze 60

Thanks to its impressive design, the Granite Gear Blaze 60 is our continual top pick for backpacking. The newest version of this model has once again earned our best overall backpacking backpack award. This pack can comfortably support up to 50 pounds and only weighs 3.0 pounds. “I love the Blaze's practical features: A stretchy mesh front pocket, roomy hip belt pockets, and removable top lid,” one of our testers states. It also has a breathable back panel, long front access zipper, and nine compression straps to handle variable loads. You can also remove the brain and the waist belt, which combine into a fanny pack for day hikes away from camp. “This bag has just about every feature you could ask for and nothing you don't need,” said our tester. It's an impressive pack in both weight and weight capacity. A light pack allows you to keep your base weight low, but since the Blaze has such a robust suspension, you can comfortably carry a few luxury items, winter/climbing gear, or extra food for extended trips.

While this backpack does many things right, there is no perfect pack for everyone. Some buckles on this model are small and hard to operate when wearing gloves. This isn't a huge deal, and the small buckles help keep the weight low, so we're okay with it. Overall, this isn't a high-tech, revolutionary pack, but the simple design is part of the appeal. The Blaze 60 keeps things simple, and by using some of the lightest and most durable fabrics available, it's light and strong. If on-trail comfort, gear accessibility, and adjustability are important to you, an alternative worth looking at is the Gregory Paragon 60. This model weighs only 1/2 pound more than the Blaze 60 and features a trampoline-style mesh back panel and a free-floating hip belt to suspend the load. It's also one of the most adjustable packs we tested, with a design that allows you to extend the hip belt padding as you lengthen the straps.

Best Bang for the Buck

REI Co-op Flash 55

The REI Flash 55 is an inexpensive, lightweight, and well-designed backpacking backpack. It weighs less than three pounds and can comfortably carry loads of up to 30 pounds. “I particularly love the Packmod system, which enables you to customize the pack for your needs by moving or eliminating virtually all external pockets and straps,” one tester states. Two “extra” side pockets exist between the water bottle and the front stretch pockets. These extra pockets are super handy and essentially double the external storage capacity. The side bottle pockets are also the most easily accessible in the group. They sit low on the pack, making it easy to grab and replace your bottles with one hand. Since water bottles go into these pockets vertically, your swinging arms won't hit them as you walk, either.

Advertised Volume	55 L
Measured Weight	2.8 lb
Weight per Liter	0.81 oz/L
Organization Compartments	Lid, front mesh pockets, 2 side pockets per side, hip belt pockets, shoulder strap pocket
Access	Top

Lightweight packs are often less durable, less supportive, and pricier. We love that the Flash 55 isn't expensive, but we have some concerns about the durability of the thin fabric. The material isn't as abrasion-resistant as some of the heavier-duty packs we tested. That said, we've seen this model last for 2650-mile thru-hikes. It is durable enough; you simply need to be mindful of how you use it. “Just don't drag it against rocks, and it will last a long time,” as one tester puts it. Also, if you plan to carry over 30 pounds, you should select a larger pack with a more robust suspension. If you're searching for a lightweight pack to carry heavier loads, take a look at the Ultralight Adventure Equipment Catalyst. At 2.8 pounds and 75 liters, the ULA packs an impressive weight-to-size ratio ideal for extended hauls. However, the Catalyst costs significantly more than the Flash. So even with the Flash's minimal shortcomings, this modular pack has a lot to offer at a modest price.

Best for Superior Comfort

Osprey Atmos 65 AG

We love the comfort and design of the Osprey Atmos AG 65 and consider it one of the best all-around backpacking backpacks. It's loaded with features and provides incredible back ventilation. This pack has earned a cult-like following for good reason. What sets the Atmos AG 65 apart the most is Osprey's innovative anti-gravity (AG) suspension, which helps spread the load more evenly across your hips and shoulders while also venting excess heat from behind your back and under the hip belt. “The plush, tapered, breathable foam shoulder straps are dreamily comfortable,” one tester states. For average trips with loads weighing 40 pounds or less, this is one of the most comfortable packs we tested. Every pocket is a good size and thoughtfully placed. Moreover, the Atmos offers an excellent fit with efficient adjustability focused on ergonomics.

Advertised Volume	65 L
Measured Weight	4.6 lb
Weight per Liter	1.13 oz/L
Organization Compartments	Lid, front mesh pocket, side water bottle pockets, hip belt pockets
Access	Top, sides, bottom

Clocking in at 4.6 pounds, the Atmos AG 65 is heavy and feels somewhat over-engineered. And although it weighs close to 5 pounds, it doesn't handle heavy loads as well as we'd like. Additionally, some of our testers found the waistbelt to be confining and “maybe a little too much like a bear hug, particularly when adjusting clothing,” as one tester puts it. All told, though, the adjustability and excellent suspension system of the Atmos make it one of the most comfortable backpacks we've tested. If you plan to haul loads of 45 pounds or more consistently, we recommend checking out the Osprey Aether 65, which features a burly suspension system ideal for tackling bigger trips.

Best Lightweight Support for Long Distances

Ultralight Adventure Equipment Catalyst

Tipping the scales at just 2.8 pounds, the ULA Catalyst borders on being an ultralight pack and is an excellent option for lightweight enthusiasts. Although this pack is incredibly light for its massive 75-liter capacity, it comfortably carries a hefty load for long stretches between resupplies. ULA packs are well-known in the thru-hiking community and are loved for having the features long-distance backpackers want, such as massive zippered hip belt pockets, a large stretchy mesh front pocket, and huge side water bottle pockets that can each hold two tall one-liter bottles. Heck, for an upcharge, they'll even embroider your trail name on the pack. If you're so inclined, there are many customized options, including some fun color combinations. This is all great stuff, but when all is said and done, as our lead tester states, “This pack is simply great for being lightweight, capable, comfortable, and feature-filled.”

Advertised Volume	75 L
Measured Weight	2.8 lb
Weight per Liter	0.60 oz/L
Organization Compartments	Front mesh pocket, side water bottle pockets, hip belt pockets
Access	Top

We downright love this pack, but we understand it might not be for everyone. If you appreciate the breathability and ventilation of a trampoline-style suspension, you're better off looking at a model such as the Osprey Atmos AG 65. For those who want a more breathable back panel in a lighter weight than the Atmos, check out the Osprey Exos 58. Although both of these packs weigh more than the Catalyst, we can't deny the comfort of a suspended mesh back panel. And the Exos is quite light considering all its features. Another consideration about the Catalyst is that it lacks a brain on top. That said, we still found ample storage in the external mesh pocket for on-the-go items. If you're looking for serious capacity without added weight, this lightweight backpack is an excellent option and one of our favorite picks for long-distance hikes.

Best for Carrying Heavy Loads

Osprey Aether 65

Osprey has always done a good job of marrying durability, adjustability, and large load comfort, and the Osprey Aether 65 is the perfect example. With its Fit on the Fly velcro adjustment system and quick-sliding shoulder straps, it's easy to dial in your ideal fit while out on the trail. This backpacking backpack makes it easy to access your gear with a sleeping bag compartment, reinforced stretch “shove-it” front pocket, a large zipper to access the pack's interior, and a double-pocketed lid that keeps all the necessities just a zip away. “The back panel and shoulder straps are firm and supportive, remaining comfortable with loads up to a whopping 50 pounds,” our lead tester claims. There are multiple compression straps to keep the weight close to your body. These straps are also useful for strapping wet gear outside your pack. When the weather does turn stormy, you can pull out the included pack cover to shelter your gear, but if the forecast is clear, you can leave it at home to save some ounces.

Advertised Volume	65 L
Measured Weight	5.0 lb
Weight per Liter	1.23 oz/L
Organization Compartments	Lid, front pocket, side water bottle pockets, hip belt pockets
Access	Top, front, bottom

The main disadvantage of the Aether is that it clocks in at 5 pounds. Though it can comfortably handle loads many lighter packs couldn't dream of carrying, this pack is undeniably heavy. The high-quality and reinforced materials, along with additional features, add extra weight. For those who prefer to move light and fast, we also like the Gregory Focal 58. This pack is substantially lighter than the Aether, yet still holds up well under heavy loads. On the other hand, heavier materials are more durable, and the Aether's features might be exactly what you're searching for. Another important consideration is that the hip belt doesn't move with you as you walk, unlike some packs. This causes the pack to sway from side to side when carrying heavy and tall loads. If you want a hip belt that moves with you and doesn't cause the pack to sway, check out the Gregory Paragon 60. However, when we need to carry seriously heavy gear, there's no pack we've tested that's more comfortable to take on hefty loads than the Aether.

Best Organizational Features

Deuter Aircontact Core 65+10

The Deuter Aircontact Core 65+10 is a great pack for those who want options for staying organized on the trail. If you want a specific pocket or space for everything while backpacking, this pack is for you. It has great organizational features, including three separate ways to access the main compartment. An interesting suite of features allows you to customize its setup. It features a sleeping bag compartment with a separate opening, which can be opened and included in the main compartment via an internal zipper. It also has two side compression straps per side, both of which are removable or reconfigurable. There are dual ice axe loops with attachment bungees on the front of the pack, which can also be removed. The brain has two zippered pockets and two more zipper pockets on the hip belt. The torso length can be adjusted up to four inches. On top of all this, the generously cushioned shoulder straps, lumbar pad, and hip belt make this a comfortable ride overall.

Advertised Volume	65 L + 10 L
Measured Weight	5.2 lb
Weight per Liter	1.11 oz/L
Organization Compartments	Lid with two zippered pockets, front mesh pocket, side water bottle pockets, hip belt pockets, sleeping bag compartment
Access	Top, front, bottom

Unfortunately, the Aircontact Core is only available in one size. Therefore, if your torso length is not within the 18 to 21-inch range, this pack won't fit you. If you're not within the 4-inch torso range of the Deuter, we like the REI Co-op Flash 55, which comes in four different size options. The Aircontact also has a forward-angled side water bottle pocket on the right side, but not the left side of the pack. So, you'll only have access to one water bottle at a time. Still, these are minor issues for an overall great backpack that keeps you organized on the trail.

How We Tested

For this review, we identified the key metrics essential to grading a backpacking backpack. Then we designed thorough and wide-ranging tests to perform in the field and the lab to fully explore each metric. We — and our friends — hiked all over with these backpacks, loaded with camping gear and food, noting what made them comfortable (or not). We combined field use (i.e., evaluating convenience on different types of trips with different aims, different gear, and in different climates) and lab testing (e.g., volume testing using thousands of ping pong balls and a volume measuring device calibrated with a 1-liter measuring cup and lots of water). We loaded them up with various gear and took to the trail on a series of adventures ranging from volcano mountaineering trips to alpine rock approaches and long thru-hikes. From the Appalachians to the Rocky Mountains to the Sierra Nevadas, we wore these backpacking backpacks on long and short trail days, testing and assessing their strengths and weaknesses along the way.

We tested models in this review with a focus on the following:

• Comfort (40% of overall weighting)

• Ease of Use (25% of overall weighting)

• Weight-to-Volume Ratio (20% of overall weighting)

• Adjustability (15% of overall weighting)

Analysis and Test Results

We put our lineup of contenders through thorough side-by-side comparison testing that assesses comfort, ease of use, weight, and adjustability. After researching the best backpacking backpacks on quality, innovation, and popularity, we purchased every pack we tested. When preparing for testing, we also considered what makes a great backpacking backpack. Here, we break down our findings by metric and dive into the nitty gritty of what makes each pack worthy of consideration.

What's the Best Value?

Backpacks, like other outdoor gear, can be quite expensive. However, the right gear is often well worth the investment. If you have ever trekked up into the mountains with a poorly fitting pack, there is no doubt you understand the benefits that a quality pack can provide. Top dollar doesn't always equal top comfort, though. Some of the priciest packs here weren't the highest performers. However, many of the more expensive packs did score quite well overall. We consider price in our value recommendations but never let price color our testing or analysis of pack performance.

The REI Flash 55 offers the best value for a backpacking backpack. It's lightweight and full of features that can be added, moved, or removed as needed, all for a reasonable price. Our favorite pack, the Granite Gear Blaze 60, offers outstanding performance at an average price, making it a great value. The Gregory Focal 58 also stood out for its value: it's more comfortable than most backpacks we tested and costs less than most. Also worth noting, the Deuter Aircontact Core 65+10 had some of the most organization-friendly features and excellent adjustability for an impressively low price.

The REI Co-op Traverse 60 costs the same as the Gregory Focal and Deuter Aircontact and comes with a rain cover. The top lid also doubles as a daypack, so you can use it for shorter hikes from base camp.

The Osprey Exos 58 is also quite affordable, only costing slightly more than the Paragon, Traverse, and Aircontact. This pack stands out for its comfortable mesh back panel that doesn't weigh as much as many similarly designed packs with a trampoline back panel.

Comfort

When testing suspension, we assessed each model's shoulder straps, waist belts, back panels, and frame design. We considered how supportive each backpack is, how well it conforms to different body shapes, and how comfortable it is. The waist belt and shoulder straps are crucial when picking a backpack. They have the most significant impact on a pack's comfort (or lack thereof). The majority of issues that bother new backpackers relate to these two areas. We took the selected models on multiple extended trips loaded with 25 to 55 pounds of food, water, and gear to test their comfort.

Padded hip belts and shoulder straps are worth very little without a good suspension to go along with them. A pack's suspension is its frame system. Frame systems include internal and external frame components (or "stays"), compression straps, shoulder straps, and a hip belt. Suspension dictates how effectively the weight of your load disperses throughout the pack onto the shoulder straps and waist belt. The frame ensures the load from the pack body rests on your hips, supported by the waist belt. We also note how well each pack transfers the weight to the front of the shoulder straps rather than the top, so your shoulders don't get crushed.

Each person's body is different, so our tests included a wide range of users, including GearLab editors, friends, and our climbing and backpacking partners, to gather a wide variety of data. When a pack seems to fit a specific body type best, we mention that in the review.

After extensive testing with typical 25- to 45-pound loads, the Osprey Atmos AG 65, ULA Catalyst, Osprey Aether 65, and Granite Gear Blaze 60 were the most comfortable overall. All of our testers agreed that the Blaze 60 was particularly comfortable, considering it can carry a heavy load in a super light, 3-pound package.

The Gregory Paragon 60, Gregory Focal 58, Deuter Aircontact Core 65+10, and Osprey Exos 58 each scored almost as well as our top-performing packs in the comfort metric.

The Osprey Atmos AG 65 offers a snug ride thanks to its trampoline-style suspension, which evenly distributes the load across the body. We rarely got hot spots on our backs or hips, even after extended travel in warmer conditions. One reason for the lack of hot spots is the heavily tapered padding in the straps and waist belt, which provides the thickest cushioning on the top of your shoulders, where you want it the most. At the same time, thinner padding in less important areas reduces chafing. At loads above 40 pounds, however, the Atmos becomes less comfortable.

The best-performing contenders for heavier loads are the Osprey Aether 65, the Gregory Baltoro 65, and the Granite Gear Blaze 60. These packs utilize high-quality foam that provides a perfect balance of support and comfort. All of the shoulder straps offer top-notch ergonomics and slightly stiffer padding. While this rigid padding is marginally less comfy, you need it when you're lugging a heavy load because it won't compress. Each of these models offers subtle advantages that will help transfer the load to your hips and keep you moving toward camp in relative comfort. These advantages include a supportive suspension, foam stiffness, and well-designed shoulder straps and waist belts. The combination lands all of them in the load-hauler category.

The hip belt is one of the primary contributors to a comfortable pack, especially when it is well-loaded. Some are light and relatively soft, while others swivel and are well-padded yet rigid to carry heavy loads. Some packs, such as the Granite Gear Blaze 60, Gregory Baltoro 65, Gregory Paragon 60, and Osprey Aether 65, allow the foam padding of the waistbelt to extend outward to accommodate larger waist sizes.

Trampoline or Suspended Suspension System

Trampoline-style or suspended suspension systems feature a tensioned mesh back panel (like a trampoline) instead of a more traditional, single-stay, double-stay, or “Y” shaped frame. These allow airflow between your back and the pack's load, reducing back sweat. More importantly, weight is distributed more evenly, producing fewer hot spots. The Osprey Atmos AG 65, Gregory Focal 58, Gregory Paragon 60, and Osprey Exos 58 all have trampoline-style suspension.

We like trampoline-style suspension systems for their breathability and weight distribution. However, not many trampoline-style harnesses can handle large loads of 45 pounds or more. Trampoline suspensions also position the load further away from your back, increasing leverage and reducing balance, which makes for a less comfortable overall carrying experience as the weight increases.

Ease of Use

This metric evaluates how easy it is to pack and retrieve items from these backpacks. In assessing ease of use, we pay particular attention to the design of the main compartment, pockets, lid, straps, and other unique attributes. We compared the number and location of pockets and how useful our testers found them to be. We measured the internal volume of the main pocket and compared it to the manufacturer's claims. We also determined how well the pack's brain provides access to small items and whether those items stayed organized.

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 seem useful for retrieving items or if they're impractical to zip shut when the pack is full and are thus just for show.

To assess exactly how much space every pack had to store backpacking gear, we tested the internal volume of each pack using thousands of ping pong balls and a measuring cylinder calibrated with a 1-liter measuring cup and lots of water. We filled every pocket of every pack with ping pong balls, then measured the total liters of the balls. We then recorded our findings and compared them to the manufacturers' claimed volume for each pack.

Most pack manufacturers are pretty accurate with their volume claims. However, there is some discrepancy in tabulating total volume: some companies count the volume of every pocket in their advertised volume, while others only count the main compartment.

The largest discrepancies between advertised volume and main compartment volume were with the ALPS Mountaineering Cascade 90, REI Co-op Traverse 60, Deuter Aircontact Core 65+10, Osprey Aether 65, Osprey Atmos AG 65, and ULA Catalyst. Each of the main compartments of these packs is at least 15 liters lower than their advertised volume.

We considered other additional features' usefulness and evaluated them in the field during real-world testing. We generally 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 awarded extra points for features that can be removed or customized for a more personalized user experience.

Overall Organizational Ability

For those who like an assortment of compartments and pockets for organization, the Deuter Aircontact Core 65+10, Granite Gear Blaze 60, and ULA Catalyst have particularly convenient pocket designs.

These models offer a similar setup and exhibit our favorite organizational and pocket layouts. They provide excellent hip belt pockets, big water bottle side pockets, and a stretchy mesh “stuff-it” pocket that is excellent for wet clothes or carrying oddly shaped items like fuel bottles, a trowel, camp shoes, or a frisbee.

For folks who love to stay super organized, the Deuter Aircontact Core, Gregory Paragon 60, and Gregory Baltoro offer excellent gear access and the ability to get to your items quickly without removing anything. If you need a ton of space to store your bulky items, the ALPS Mountaineering Cascade 90 features the largest main compartment, along with ample external storage.

Top Lid Pocket (aka The Brain)

Every pack, other than the ULA Catalyst, has a top lid with a zippered pocket, and many of them can be removed and left at home to reduce weight. The top lid is one of the best places to store small items that require quick and easy access, such as sunglasses, sunblock, or bug spray. Many models also have a separate small pocket on the underside of the lid, offering a secondary place to keep small items that don't need to be accessed as frequently, like car keys.

Most packs have zippers on the front or back of the lid, which means that it's not as easy to get inside them without removing the bag. Additionally, not all side-zippered lid pockets are the same. The sizable zippered lid pockets of the Osprey Atmos AG 65 are next level. The Gregory Baltoro 65 also has a very wide opening zipper on its lid.

Pack Access

How you access the primary compartment on the backpacking pack is part of our Ease of Use metric and measures how easily you can grab a few items without unpacking the entire bag. The value placed on this metric depends on the user and the pack's volume. As pack volume increases, access takes on greater importance.

While ease of access is important, too many features will add weight to the backpack. Don't select a pack solely for an elongated zippered access panel, especially if you will rarely use it. That massive zipper will add a lot of weight to the backpack. Also, many side access panels are a pain to close when the pack is fully loaded.

All the backpacking backpacks in our review are top-loading; many have a separate sleeping bag compartment with a bottom access zipper, including the Osprey Atmos AG and Aether, the Deuter Aircontact Core, the Gregory Baltoro, the Gregory Paragon 60, REI Traverse 60, and the ALPS Cascade. These openings enable access to a part of the pack that is hard to get at from the top without unloading everything onto the ground first.

Additionally, some packs have access to the main compartment through the front or sides. The ones in our lineup with this access are the Granite Gear Blaze, Osprey Atmos and Aether, Deuter Aircontact Core, Gregory Baltoro, Gregory Paragon, and REI Traverse.

Hip Belt Pockets

A pack with a good hip belt is critical; pockets can make or break a hip belt. We especially love the hip belt pockets on the Granite Gear Blaze 60, Gregory Baltoro 65, Gregory Focal 58, and the ULA Catalyst for their unrivaled size and ease of access. The Deuter Aircontact Core features waist belt pockets made of stretchy mesh, allowing them to fit even more than their appearance suggests.

The Osprey Exos 58, on the other hand, has some of the smallest hip belt pockets we tested. Each pocket is barely big enough to fit a smartphone that is 5.9 inches tall, 2.8 inches wide, and 0.4 inches deep. Previous versions of this pack didn't have hip belt pockets at all, so these smaller pockets are better than nothing, but you can't cram as much into them as the models mentioned above.

Hydration

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

Rain Covers

Rain covers are a practical addition to any backpacking pack. If the rain is falling for days at a time, unless you've lined your pack with a trash bag or packed your gear in dry bags, your stuff will get wet. A pack cover can only do so much to lessen this reality, but it helps prevent excess water from soaking into the pack fabric, which will weigh down your pack. The backpacks that include a rain cover are the REI Traverse 60, Osprey Aether 65, and the ALPS Mountaineering Cascade 90.

Weight-to-Volume Ratio

The weight of the pack itself affects how heavy it feels on your back almost as much as the gear you're carrying does. This seems obvious to say, but a heavier pack will feel, well, heavier. While we aren't talking about ultralight packs here, we still think it's worth considering how much a pack weighs. A lighter pack will be easier to hike with, after all.

We measured each pack on our home scale to verify the manufacturer's claimed weight. Then, we calculated the weight-to-volume ratio of each pack. A smaller pack will weigh less because it's made with fewer materials, but if that means you can't carry all your backpacking equipment, then a few extra ounces might be better.

The lightest packs in our review, by a significant margin, are the REI Flash 55, ULA Catalyst, Gregory Focal 58, Osprey Exos 58, and Granite Gear Blaze 60. These packs weigh in at 3.0 pounds or less and ride the line between backpacking backpacks and ultralight minimalist packs. The primary difference is that these models are more comfortable for individuals with a base pack weight of 20-25 pounds or less.

These lighter packs are excellent options for folks who want to go light but still want a comfortable and supportive pack with a frame and robust padding for heavier loaded trips. A lower initial pack weight also helps with longer food carries or that first day of a week-long backpacking trip, when those seven days' worth of food is heavy no matter what the rest of your gear weighs. Due to their lightweight design and excellent weight-carrying capacity, these packs are popular among long-distance trail hikers.

It's worth noting that sometimes lightweight packs sacrifice load-carrying abilities and organizational features. If your backpacking setup is dialed, you may benefit from a lightweight pack, but not necessarily. Packs that weigh more will have more pockets and often have a more robust frame, making a heavier load feel more comfortable. On the contrary, if you overload a lightweight pack that isn't designed for a heavy load, it won't be comfortable.

Adjustability

To judge each backpack's adjustability and fit, we considered its overall ergonomics and how adjustable each model was. We also looked at the range of torso lengths available. More sizes mean it could work for a broader range of users.

Many packs we tested feature a way to move the shoulder straps up and down to adjust the torso length. These include the Granite Gear Blaze 60, REI Flash 55, REI Traverse 60, Osprey Atmos AG 65, Osprey Aether 65, Gregory Paragon 60, Osprey Exos 58, Deuter Aircontact Core 65+10, and ALPS Mountaineering Cascade 90, which all allow you to adjust the torso length vertically on the pack to dial in your perfect fit.

The adjustment options of the Osprey Aether 65 are quite notable. While it may only have four inches of vertical adjustment, it also has adjustable shoulder straps and waist belt padding that help dial in your perfect fit while on the trail.

The Gregory Paragon 60 has a very adjustable hip belt as well. Most packs allow you to adjust the hip belt size by simply changing the length of a webbing strap. With the Paragon, however, the cushioning for the hip belt can also be extended, allowing people with wider hips to still have cushioning where they need it.

The Gregory Baltoro 65 and Osprey Atmos AG 65 also have a respectable amount of adjustment. They also feature roughly four inches of vertical adjustment and are available in a variety of sizes. The REI Flash 55 is available in a unique extra size: a large torso with a small waistbelt, which is useful for those tall, skinny folks out there.

Conclusion

Traveling from point A to point B on a backcountry trip seems simple enough, but choosing the right backpacking backpack to get you and all your gear to the end in the best shape possible is a bit trickier. You can choose from many options, each geared toward a certain type of packer and hiker. We hope that our testing and analysis have helped you narrow down the choices so you can select the best option for your needs and your budget.
