Best Backpacking Pack

Gregory Baltoro 65

Gregory Mountain Products Men's Baltoro 65, Onyx Black, Small

The Gregory Baltoro wins our vote as the best backpack for backpacking in 2021 for a number of reasons. It’s light, tough, well-thought-out, far more practical than most of its peers, and so comfortable that it’s almost a pleasure to wear, even when carrying a full load. 

The Baltoro uses a Rotating Load Transfer Disc that allows the hip belt to pivot, enabling it to conform to your natural movements for enhanced agility and stability. This does an excellent job of distributing the load weight and makes the going far easier on bumpy trails and in trickier terrain. 

The Baltoro features a grid-lock system that allows easy fitting by adjusting the straps either vertically or laterally for a custom fit that will conform to most body shapes.

With regard to organization, the Baltoro leaves most of its competitors in the shade. In addition to a wide opening and spacious central compartment, it boasts a large kangaroo pouch, huge U-shaped zipper panel that lets you access your gear from any side of the pack, two external top lid pockets, and side zipper pockets for water bottles, cameras, or even a bear canister.

This compartmentalized design not only helps to keep things tidy and provide easy access to your gear, it also helps to stabilize the load by encouraging even weight distribution and centering your load in the optimal position. 

Bottom line: A hard-wearing, trail-ready pack that goes the extra mile in terms of comfort and convenience.

Things To Consider When Buying A Backpacking or Hiking Backpack

Purpose/Carrying Capacity/Length Of Trip

The capacity you need in a backpack will be highly dependent on two things; 1) the duration of your trip and 2) how minimalist your backcountry MO is. 

The backpacks in this review (45L to 65L backpacks) are good for a weekend trip for gear-intensive folks, such as beginner backpackers, but are also big enough to carry all the gear a lightweight hiker will need for extended trips of 5+ nights. If you plan on taking on a longer, multi-week trip, however, we recommend choosing a 70L backpack or even an 80L backpack.

Traditional Guidelines for Pack Size Based on Trip Length

Length of Trip

Pack Volume (Liters)

Single Day/Overnight (1-2 nights)20 – 50
Weekend (2-3 nights)50 – 60
Multi-day (2-5 nights)60 – 80
Extended (5+ nights) 80+

The above table is mainly for beginner hikers who have yet to economize on gear choices or hikers who need to carry a lot of equipment for other activities, such as climbing or slacklining, or parents who need to carry extra kit for their children.

The table below gives an attainable pack size for those able or willing to economize and pack only the items you truly need. However, bear in mind that choosing to pack ultralight camping gear will often require finding smaller packed size items, which are often more expensive than their bulkier competitors.

Streamlined Guidelines for Pack Size Based on Trip Length

Length of Trip

Pack Volume (Liters)

Single Day/Overnight (1-2 nights)20 – 30
Weekend (2-3 nights)30 – 50
Multi-day (2-5 nights)45 – 55
Extended (5+ nights)55+


There is nothing more important than having a good fitting backpack. This is because the proper fit will ensure that the load is distributed in an 80/20 ratio, with the majority of your load squarely on your hips and lower body, only 20% on the front of your shoulders, and no weight on the top of your shoulders. 

Doing so will allow the pack weight to rest on the stronger lower body rather than the weaker muscles of the torso and shoulders. 

To get the right fit, measure the length of your back from the C7 vertebrae at the base of your neck to the center point of your spine between the tops of your hip bones. This spot is called the iliac crest, and it is where you will be carrying most of your pack’s weight. Compare this measurement to the measurements listed with any potential purchase.


Carrying a heavy load on your back for multiple days on end can be a nightmare if your pack’s comfort levels are anything less than optimal.

If you are planning on carrying heavier loads and/or for longer trips, you may want to look for backpacks with more padding on the straps and an overall better suspension system.

Other comfort-enhancing features to look for include wider hip belts (narrow ones can chafe), ample cushioning in the back panel, and a ventilation system in the back panel that will permit free airflow, reduce sweating, and thus also reduce the risk of chafing or abrasion during longer days on the trail.


Unfortunately, weight tends to come as a trade-off with comfort and convenience. The more padding and features a pack has, generally speaking, the heavier it will. Conversely, minimalist models that offer only light cushioning/padding and very little in the way of add-ons tend to be the lightest. 

Also bear in mind that a 60L backpack is likely to weigh considerable more than a 40L pack, so don’t choose a model that’s far bigger than you need if weight is a concern.

Again, deciding which type of pack is best for you will hinge on prioritizing your needs and preferences. 


There are two types of frame systems for hiking and backpacking backpacks: internal frame vs external frame

External frames are those that have hollow tubing, made of materials such as aluminum and graphite, to support the weight of the pack. There has been a trend away from external frames, but they can have many benefits.

An external frame backpack carries your load higher on the back, which, counterintuitively, allows you to maintain the majority of its weight on your lower body. Having the weight centered here is better less fatiguing with heavier loads. 

This weight transfer also allows for a more upright posture so you can see more of what is around you and spend less time staring at the ground. This type of backpack is also perfect for hot weather, since the frame suspends the pack away from your back, thus allowing more airflow between you and the material of the backpack.


External frame backpacks are far less common and often tricky to find. However, when you do find one, they usually cost a lot less than similarly sized frameless packs, so they’re a good option if you are on a tight budget.

However, external frames also have a few disadvantages. 

Since the weight is carried high and away from your back, you may feel off-balance when hiking in difficult terrain with this type of pack. Also, external frame backpacks aren’t the best for forest hikes because they get caught on branches fairly easily. And finally, of course, the frame itself can add up to 2 pounds to the pack’s weight, making them far from ideal for the gram counters.

Internal frame backpacks also come with several advantages and disadvantages. 

First, internal frames, being much more popular, come in a wide diversity of styles and sizes. They are easy to find, and new, ever more innovative models appear on the market almost monthly. Because internal frame packs are streamlined and compact, they are less likely to get caught on or damaged by brush and branches, allowing you to go off-trail as much as you like.

Also, this style of pack is more comfortable to wear because less pressure is placed on the user’s back by the frame. 

Unfortunately, internal frame backpacks can be both harder on the shoulders and back because of the low distribution of weight. They also offer less in the way of ventilation because the pack’s back panel is worn directly against the back. Finally, being more popular and innovative, these backpacks are also more expensive, so you will want to budget accordingly.

Compartments & Pockets

Some people enjoy the simplicity of a single compartment, while others celebrate the organization of several compartments. Both have their advantages and disadvantages. 

Single-compartment backpacks generally weigh less because of the lack of extra fabric used in their construction. If you prefer easy loading and unloading over organization, you will delight in the fuss-free simplicity of a single-compartment pack.

However, these packs can make it trickier to access your gear, particularly if they use a single opening and consolidate storage in one large central compartment. 

That said, if you change your mind post-purchase and decide you want the organization of a compartmentalized backpack, you can get the same effect with stuff sacks, though you will still have only a single access point. 

For longer trips and trips with children, you will probably want easy access to individual items without constantly having to unpack everything. For this reason, it may be wise to invest in a backpack with multiple compartments and/or access points.

Considering your first thru hike? Then let us help you plan the way ahead.

Women/Youth Specific

If you are female or are buying a pack for a younger hiker, you should give serious consideration to the purchase of a women’s-specific or youth-specific pack.

Women’s backpacks (and youths) tend to be shorter and narrower than mens hiking backpacks. Additionally, the hip belts and shoulder straps on a woman’s packs are shaped with the female form in mind.

Pack Anatomy & Design Features

Main Compartment

The majority of backpacks have one large top-loading compartment for storage of the majority of your gear. These packs sometimes also provide access to this main compartment from below or from the sides with zippers that allow you to dig out individual items without unloading the full bag.

Back Ventilation

To help alleviate the issues of sweaty backs while carrying a load, many packs have a breathable mesh back panel that allows a few inches of cool air to travel between your back and the pack proper allowing any moisture to evaporate, rather than seeping through your clothes and backpack.

Others use molded foam back panels that permit airflow through deep grooves in the foam.

Packs that use neither are liable to become very sweaty very quickly. This will not only make the pack heavier but also mightily uncomfortable and almost sure to cause chafing on longer hikes.

Hip Belt Pockets

With up to 80% of the weight of the backpack supported by your waist at any one point in time, a well-fitted and padded hip belt is hugely important. Without one, you may quickly find sore spots developing on your hips and lower back.

While the main purpose of the hip belt is to support the weight of the pack, more recent models of backpack often feature pockets in the hip belt that provide easy access to small items you like to keep to hand. This handy feature can help to keep your hands free, saves having to take your pack off to access essentials, and frees up your pant and jacket pockets. 

Shoulder Straps

Although a pack’s weight should be distributed so that only 20% rests on the shoulders, 20% of 15, 25, or 50 pounds can become mightily uncomfortable if the shoulder straps on your pack do not have sufficient padding.

To prevent soreness on your shoulders, we recommend choosing a pack with thick foam padding and wider straps that distribute the weight more evenly across the breath of the shoulder strap instead of digging into your skin.

Load Lifter Straps

Load lifter straps are found at the top of the shoulder straps and are there to prevent the top of the back pulling away from your body. When adjusted correctly they should form a 45° angle between your shoulder straps and the pack, which should help keep the pack snug against your upper back.


The choice of fabric the pack is made from plays a large role in how waterproof it will be. The majority of packs are made from nylon. This fabric does offer some resistance to the elements, but a continual downpour will quickly see the contents of your pack get damp, if not through the fabric itself, then at least through the seams and pockets.

You can also look for a pack made from Dyneema (also known as Cuben Fiber) which is significantly more waterproof. However, the most surefire way to keep your kit dry is to buy a rain cover for your pack.

Pockets & Attachment Points

If you are hyper-organized, or simply need to access items quickly, then a pack with multiple pockets and/or external attachment points might be the way to go. There are various options:

  • Trekking pole and ice axe loops
  • Hip belt pockets
  • Shoulder pouch
  • Water bottle holsters
  • Rear mesh pocket
  • Sleeping bag compartment
  • Daisy-chain attachment points
  • Molle-style attachment points
  • Kangaroo pouch pockets 

Hydration System Compatibility

Keeping well hydrated on any trip is a must, and many packs offer a special internal sleeve or pouch that will hold a water bladder or reservoir, with holes/clips to hold the port. These systems typically hold around 3 liters of water, though are nearly always sold separately from the main pack.

Removable Top Lid

A few packs come with a removable daypack or top lid that can be used for day hikes from your basecamp, which saves you carting around a small load in a huge backpack.

The Perfect Fit – How To Size A Backpack

Many backpacks come in a variety of sizes, and to ensure maximum comfort while out in the backcountry it is essential that you buy one that fits your measurements. To do this, you will need two measurements; your torso length and your hip size.

To measure your torso size, first tilt your head forward and feel for a bony bump, where your back meets your neck. This is the C7 vertebra. Next feel for the top of your hip bones using both hands on your sides. Once you have found these, measure the distance between the center point on your back between the top of your hip bones to your C7 vertebra. 

We recommend getting someone to help you do this to get the most accurate measurement.

Measuring your hip size is a little more straightforward. Find the top of your hip bones again, and simply measure the circumference of your waist at this height.

Correctly Adjusting Your Pack

To do this, you need a correctly fitted waist belt. When you try on the backpack, loosen the shoulder straps and tighten the waist belt around your waist. It should fit snugly around your waist and not have any gaps. 

Next, turn your attention to the shoulder straps. They should, once cinched, attach to the pack about two inches below the top of your shoulders. If they attach at a different point, adjust accordingly or move up or down a size as needed.

The third part of the backpack to consider is the shape of the shoulder straps across the shoulders. The straps should fit snugly across the front of the shoulders, just graze the top, and then curve down to meet the pack. 

With the straps adjusted correctly, you should be able to place a finger between the straps and your shoulders, but not more than one because the closer the strap is the less it will move from side to side.

Finally, the sternum strap should rest snugly across your sternum in the middle of the chest. You should also be certain that the pack sits against your back with no gaps. This will ensure the center of gravity remains close to your body and help to improve your balance, particularly with heavy loads and/or on rougher trails.

The Best Packs For Backpacking Reviewed

Osprey Exos 48

Best Lightweight Backpack

Osprey Exos 48 Men's Backpacking Backpack, Blaze Black, Medium

Weighing only 2.35 pounds, the Osprey Exos 48 is a single-compartment backpack with shoulder strap pockets and three mesh pockets on the front and sides. The winner of our best lightweight pack title also has a detachable top lid and floating pocket, multiple cord tie-off points, and a padded hip belt. The peripheral frame, a wire that runs along the exterior of the back panel, allows the pack to carry away from the back, so there is plenty of airflow, but the gear must conform to the shape of the backpack, leaving gaps inside and wasting space.

There is also an internal back panel with a clip attachment for a bottle or hydration kit up to three liters in size. An underarm trekking pole loop carries your poles when not in use, allowing your hands to free when you need them most. With the help of torso-specific sizing, you will likely be able to find the perfect size for your body.

If you are a minimalist, this backpack will get you through the week, but otherwise, plan for a larger bag such as the Ula Circuit or Kelty Coyote 80. Also, the pack often squeaks due to the rubbing of the external wire against material of each corner. A final note on this bag is that it cannot stand on its own, so you will need to brace it against something or hold it with one hand while searching through it.

Looking for a bigger size? Check out this pack’s larger sibling, the Osprey Exos 58.

Key Features

  • This pack rides smooth, perfectly balanced and is very light at 2.4 pounds.
  • The aluminum struts give strong support, unlike airframes
  • No-sweat fabric on the back of the pack
  • Three points of adjustment on the seamless mesh straps for a perfect fit
  • The lid, the attachment points, and the key straps can all be removed
  • The shoulder straps have a gel insert to protect the muscles and make it more comfortable

Osprey Exos 48 Review

  • PROs

    • Trampoline mesh back kept us cool even in the high 80’s with a full pack
    • Foam-padded hip belt stops bumping and chaffing
    • Detachable pocket is big enough for a day pack for a short side trek
    • Floating top pocket has a mesh compartment inside and outside, plus room underneath for storage
    • Perfect weekend backpack
  • CONs

    • No straps for a sleeping bag or tent attachment at the bottom of the pack
    • There is no coating on the aluminum frame, so after a while, it creaks and squeaks.
    • Pockets in side are awkwardly placed, tilted at an angle that is slanted too far forward

Kelty Redwing 50

Best Budget

Kelty Redwing 50 Backpack, Black

Weighing in at 3.19 pounds, the Kelty Redwing 50 has a hybrid U-shaped zipper and top compression clips to give you the choice of top- or panel-loading. It offers great organization, with zippered side pockets and stash pocket, a large front pocket with organization for small gear items, a large pocket on the top, and dual pass-behind side pockets.

The frame is made up of an aluminum stay and a polyethylene sheet, both of which are removable to lighten the load, though you lose the support of a frame. A mesh front panel, along with mesh on the shoulder straps, provides good airflow, preventing your back and shoulders from overheating.

A dual-density waistbelt and lumbar pad give you comfort and support, while fixed suspension offers all-day carrying without the need to stop and adjust. It does, however, disallow adjustment of the fit. For some people, this may be an issue because they will want to change the fit based on the comfort level, which changes throughout the day.

A hydration pocket with two clip attachments can fit a bladder up to three liters or be a hidden pocket for a laptop. There is even a hydration tube port, negating the need to run your tube between the zippers of the top lid. The Redwing’s front stash pocket has a webbing handle, which makes short-distance carrying easier and is also a perfect place to clip a camp mug, trekking pole or small first aid kit.

One final benefit of this pack is its torso and hip belt sizing, which makes finding the right fit that much easier. Finally, though it can be made to work, particularly if you are a minimalist, the size is just not quite big enough for a full week’s gear. Our pick for the best budget hiking backpack.

Key Features

  • Well-padded and ventilated back panel with LightBeam aluminum stay with removable padded waist belt
  • Kelty’s PerfectFIT™ suspension
  • Integrated padded hydration sleeve doubles as laptop sleeve
  • Side compression straps
  • External gear loops
  • Front organization pocket, water bottle pockets, and tent pole/hiking pole pockets

Kelty Redwing 50 Review

  • PROs

    • Stuff pocket for jackets or other bulky items
    • Hybrid U-shaped central compartment zipper allows access from top of pack and sides
    • Hidden daisy chain and hook to attach additional gear
    • Fantastic suspension system that allows a highly customizable fit
    • Weight: 3 lbs 2 oz
  • CONs

    • Fabric choice cuts down on weight but is vulnerable to punctures and rips
    • Very tall or very short individuals may have difficulty with the suspension
    • Chest strap is weak and prone to breaking

Osprey Atmos 65 AG

Best Camping Backpack

Osprey Atmos Ag 65 Backpack, Abyss Grey, Large

A comfortable and versatile pack, the Osprey Atmos 65 AG weighs in at 4.39 pounds, a decent weight for this size pack. If you need something lighter, however, try the Ula pack or, alternatively, remove the top lid to save a bit of weight and the flat jacket compression will protect your gear from the elements. The top lid can also be extended if you need extra room for your gear, though be careful not to overload this pack.

It’s recommended load weight is 30 to 50 pounds and if you go over 50 lbs, the frame starts to lose shape, and the bag loses its comfortability. If you need to carry loads heavier than 50 pounds, check out the next pack, the Gregory Baltoro as a great alternative. Under 50 pounds, however, the antigravity suspension of this pack does an excellent job of spreading the weight of your gear evenly, avoiding pressure points or hot spots and providing a very comfortable ride.

While the suspension system provides support, the internal and external compression straps provide stability to the load, ensuring that there will be little shifting as you hike.

Available in only three sizes, this pack nonetheless fits most users because of its great torso length and waist belt adjustment system. Full of pockets, this is not the bag for you if you prefer to go minimalist.

If organization is your game, however, you will delight in the number of pockets on this pack. It starts with a large stretch beaver-tail pocket for stowing away gear that is awkward to pack, like sandals or a fuel canister. Behind this pocket, two zippered medium-sized gear pockets give easy access to items you will need during the hike. Below this is a zippered sleeping bag compartment with a removable divider, two zippered lid pockets, and removable straps to carry a sleeping pad. On each side is a bottle pocket, which accommodates a traditionally vertical bottle or allows you to tilt the bottle forward for easier access while the pack is on.

Finally, you can store a cell phone and camera in the waist belt’s two zippered pockets for quick access on the go. On the outside of the pack, there is also a stow-on-the-go trekking pole attachment system to give you full access to your hands when you need them. Overall, this is one of the most versatile and comfortable hiking packs on the market.

Key Features

  • AntiGravity™ 3D suspended mesh backpanel with Fit-on-the-Fly™ adjustable hipbelt
  • ExoForm™/BioStretch™ harness with load lifter ‘bar’
  • Stow-on-the-Go™ trekking pole attachment and twin ice axe loops
  • Compatible with Hydraulics™ Reservoir
  • Top lid access and FlapJacket™ top cover for use without lid
  • Integrated & detachable raincover
  • Sleeping bag base compartment with internal divider
  • PROs

    • Great organization with lots of gear pockets
    • Awesome ventilation and great adjustability
    • Removable components that can save some weight
    • Very comfortable
  • CONs

    • Gets a bit ungainly with heavier loads

Gregory Baltoro 65

Editors Choice

Gregory Mountain Products Men's Baltoro 65, Onyx Black, Small

This is not the lightest backpack at 4.9 pounds, but if what you want is ultra-comfort on the hike, consider the Gregory Baltoro 65 a real contender. One of the reasons for this is the A3 suspension which, among other features, allows the shoulder straps and waist belt to pivot to the perfect angle to evenly distribute the load weight. Another reason this pack is so comfortable is the custom fitting possibilities.

While the pack only comes in three torso lengths, it has a waist belt and shoulder harness that can be swapped out for a custom fit. There is also a foam lumbar support foam pad, but it may be a bit too much foam. Fortunately, it is removable if you desire.

Organization is another great feature of the Gregory Baltoro 65 due to the variety of pockets. On the inside, the central compartment can be used as both a top- and panel-loader thanks to a U-shaped zippered front access point, and a sleeping bag compartment with removable divider can give bottom access to the pack as well. The removable bag may not be very useful as a day pack, but it is great as a hydration bladder holder or extra organization within your main compartment. Besides the traditional two bottle holders with drawstrings, there is an additional holder on one side, providing further room for necessary water bottles.

While there are two waist belt zippered gear pockets coated for water-proofing, these pockets do not fit all cell phone sizes, so you may want to look at another pack if you have a larger smartphone.

Another benefit of this pack is that it comes with a rain cover, saving you money you would have spent getting one. One disadvantage of this pack is that if you have a short torso, you lose about eight liters of capacity, which is enough to make this pack go from a great size for a week-long trip to a not-so-good one. It is recommended that if you have a short torso, you put up the extra money to get the next size up, as it will offer you the room needed for that week’s trip. Conclusively one of the top packs for its comfort and organization, this pack has something for almost everyone.

The women’s version of this pack is called the Deva.

Key Features

  • Double Barrel dual-sided lid compartments with internal divider for increased on-trail organization
  • Stretch mesh water bottle/trail stash pocket
  • Multistraps removable via girth-hitch, adjustable straps that can be positioned at multiple lash points on the exterior of the pack for carrying a sleeping pad, outerwear, camp shoes, dirty laundry, etc.
  • Reflective zipper pulls
  • Sidekick pack combination hydration reservoir sleeve and ultra-light removable daypack, perfect for unscheduled day trips, summit hikes, or supply runs into town during a thru-hike
  • Main access top-loader
  • PROs

    • Incredibly comfortable
    • Easy access via the huge u-shaped opening
    • Able to hold larger, heavier pack weight better than other packs in the review
    • Dual zippered lid pockets
    • Organization is brilliant
    • Hipbelt pockets
  • CONs

    • Heaviest bag in terms of weight to volume ratio in our review

North Face Terra 65

Best Large Hiking Backpack

The North Face Terra Backpacking Backpack, TNF Dark Grey Heather/New Taupe Green, L-1X 65 L

An average weight for the size, the North Face Terra 65 weighs 4.36 pounds. At first glance, this is a minimalist, no-frills backpack for a week or two of backpacking. However, it contains many surprise features.

The first feature that is great is the main compartment that can be accessed via a wide mouth at the top or a side zipper. This side zipper access point allows for easy access to all the contents of the bag without having to unpack.

The frame, made up of a polyethylene frame sheet and dual aluminum stays, offers all-day support and comfort. A custom fit can be achieved with the optifit system, which adjusts to a variety of torso lengths.

If you want external pockets, this is not the bag for you, as that is lacking, but it has plenty of organization on the inside, from a top lid compartment to a bottom sleeping bag compartment with removable divider. It also has an internal hydration bladder sleeve that holds up to three liters and the traditional external side bottle pockets, so there will be no concern about hydration.

While there is a vertical ventilation panel, it may not work well enough to keep your back dry, though it will probably prevent it from being drenched in sweat at the end of the day. Overall a comfortable pack, what it lacks in external gear pockets it certainly makes up for with internal ones.

Key Features

  • 65-liter technical pack features a user-friendly design
  • OPTIFIT™ suspension fit system ensures comfort
  • Padded shoulder harness is sleek and anatomical
  • Improved, anatomically correct, load-spreading hipbelt is lined with soft air mesh
  • Huge zippered side entry to main compartment
  • Improved zippered sleeping bag compartment access
  • PROs

    • Great internal organization
    • Comfortable
    • Durable
    • Relatively inexpensive
    • External gear loops
  • CONs

    • Ventilation could be improved
    • Lack of external pockets

ULA Circuit

Best Ultralight Backpack

ULA Circuit Product Image

Able to hold about 68 liters of gear, the Circuit weighs in at an astonishing 2.2 pounds. The main compartment secures with a roll-top closure with an extension collar to hold more stuff when you need it and stow out of the way when you do not.

Certainly not a minimalist pack, the Circuit has two interior accessory pockets, one for hydration bladders and the other for cash, cards, and other small valuables.On the exterior are two large mesh side pockets, two bottle pockets with drain holes, and a front mesh pocket. One issue with the large pockets in the side is that, while they are ideal for storing larger water bottles, the design does not allow you to reach back and pull out its contents while walking. However, the adjustable hip belt also has two pockets, both zippered, for quick-access items such as cell phone or camera.

Not only does it have lots of pockets, but it also has lots of external attachment points, from the axe holders to the sleeping mat cables. The side panels have compression straps for securing longer items, and the front panel has zigzag cabling for more external attachments.

The frame is comprised of a thin plastic sheet, aluminum stay, and a fiberglass cable along the exterior of the back panel that is open to the bottom. These three components give ample support for up to 35 pounds of gear while still allowing the bag to fit to the contours of your back. A webbing handle over the roll-top offers a comfortable way to carry the pack short distances without replacing it on your back.

Padding or mesh covers the entirety of the back panel, shoulder straps, and hip belt, but watch out because the mesh easily attracts debris if you go off-trail. Best of all, the Circuit comes with an unconditional, albeit non-transferable, lifetime warranty. Able to carry a week’s worth of gear, this lightweight pack is well worth the price. A great backpack for the gram-counting minimalist.

Key Features

  • 68 Liter total capacity
  • Large extension collar for extra storage & many external attachment points for bulkier items
  • Two side, large rear mesh, and hip belt with two zippered exterior pockets
  • Internal frame and suspension
  • One hydration pocket and one small pocket for valuables in interior

ULA Circuit Review

  • PROs

    • Sturdy hip belt pockets make for excellent durability
    • Unisex thanks to multiple strap options
    • Extension collar provides extra gear space when necessary, rolls up when not
    • Replaceable hip belt with varied size options for comfortable custom fit
    • Weight: 2 lbs 2 oz
  • CONs

    • Water bottle side pockets are too far to reach back
    • Overloading bottom compartment with gear can lead to back panel pushing into your back
    • Spacer mesh can pick up small leaves and pine needles for annoying cleanup
    • Small objects not recommended inside water bottle pockets, can fall out through front pocket opening

Arc’Teryx Altra 65

Best Lumbar Support

Arc'teryx Men's Altra 65 LT Backpack Carbon Copy Regular/Tall

One of the most comfortable hiking packs on the market, the Arc’teryx Altra 65 is right up there with packs like the Gregory Baltoro 65 and the Osprey Atmos 65 AG. At 4.94 pounds, this pack is about average for its size range, but you may not even feel the weight because the pivoting waist belt does such a good job distributing the load weight. While the waist belt’s padding is just right, the shoulder straps have a little less than expected. It is not terribly uncomfortable, but it seems a little skimpy.

After the Gregory Baltoro 65, the Arc’teryx Altra 65 has the best lumbar support of all the packs on this list. It also comes in second behind the Baltoro for ease of carriage for large loads more than 60 pounds but is ideal for loads up to 50 pounds. Some of the greatest features on this pack are its storage options. A large kangaroo gear pouch is accessed by a U-shaped zipper panel with four zippers to allow you to access the pouch from anywhere on the pack. Another great pocket is the two external top lid pockets, which are zippered and are awesome for quick access to small items without having to dig through the main compartment.

Instead of open mesh bottle pockets, this backpack offers two zippered side pockets that can easily hold water bottles but are also perfect for more quick access to small items, since they will not fall out.

For easy fitting, the Altra features a grid-lock system that can adjust the shoulder straps either vertically or laterally, making a custom fit to most body shapes simple to achieve.

More expensive than the other packs reviewed, this backpack still deserves five stars because of comfort, versatility, and an excellent fitting system.

Brian has been an avid hiker and backpacker since he was a small kid, often being taken out into the wilderness on trips with his father. His dad knew everything about nature and the wilderness (or at least that's how it seemed to a ten year old Brian).

After high school, he went to university to read for both a BS and MS in Geology (primarily so he could spend his time outside rather than in a classroom). He's now hiked, camped, skied, backpacked or mapped on five continents (still need to bag Antartica) & 30 of the US states.
