The revolutionary Anti-Gravity Suspension system in the Osprey Atmos AG 65 delivers an unparalleled balance of support and ventilation. Load-hauling capability and smart organization add to the pack's hard-earned trail cred.

An engineering work of art as much as a carrying system, Osprey's Anti-Gravity Suspension system equips the Atmos AG 65 with weight-carrying efficiency, breathability, and a contoured fit that'll nearly make you forget you have it on your back. A broad-mesh, tensioned backpanel stretches seamlessly from the shoulder straps all the way out across the hipbelt. Though the pack maintains constant, responsive contact with the wearer, warm air can escape freely because of the separation caused between the mesh and the pack itself. Innovative stiffeners in the load-lifters even enable the shoulder straps to stand away from your body without jeopardizing performance. Beneath the mesh, a lightweight aluminum frame provides support and distributes weight. A sliding sternum strap and an adjustable Fit-on-the-Fly hipbelt with extandable padded "fins" further enhance fit. Accommodating backpackers of different heights, the pack is available in your choice of sizes. The Small Atmos AG 65 fits torsos ranging from 16"-19", the Medium fits from 18"-21", and the Large accommodates torso lengths ranging from 20"-23". Built in adjustability in the harness makes it easy to reset the height of the shoulder straps to offer the best fit within those stated torso ranges.

Designed to comfortably carry 30-50 pounds of gear, the Atmos AG 65 lends versatility for outings ranging from overnight trips to fast-moving, light-packing extended backpacking trips. The Small size offers 3783 cubic inches of storage capacity, the Medium offers 3967 cubic inches, and the Large Atmos AG 65 has a 4150 cubic inch capacity. The main packbag has full top access and a divider between the main compartment and a separate front entry sleeping bag compartment allows for organization of wet and dry gear. When hauling longer items or in need of access between the two compartments, you can unbuckle the divider and convert the Atmos AG 65 to a single, large compartment.

Dual front pockets are accessed through welded weather-resistant zippers. A welded, stretch woven nylon pocket on the front of the pack allows you to stash extra layers or other gear. Dual zippered pockets located inside the floating lid of the Atmos AG 65 provide other organizational options. If you want to save weight and/or you are traveling light, you can remove the lid entirely and use the integrated, low-profile FlapJacket lid to keep the contents of the packbag fully protected. Side compression straps help you cinch down your load and also serve as lash points for additional gear. Stretch woven side pockets are the perfect place for stashing water bottles or other smaller items.

Other features found on the Atmos AG 65 include integrated trekking pole loops and removable straps located in front of the sleeping bag compartment that securely stow sleeping pads. An internal lined sleeve and dual exit ports combine to make the Atmos AG 65 hydration compatible (hydration system not included). Zippered mesh pockets on the hipbelt keep snacks and essential items within easy reach.

Constructed of lightweight, abrasion-resistant fabrics, the Osprey Atmos AG 65 is available in your choice of sizes and colors.

Likes: Lots of room and pockets pockets pockets for this bag, able to fit all the necessities plus cube for my dslr.

Dislikes: Kind of wish they created something for loose strap/organization; but I am just nitpicky. Other than that Love this pack!

All around great backpack!
Reviewed by SCW - February 19, 2019

Likes: Back doesn't get sweaty.
Like the large space compartments within the backpack, the hydration bladder compartment, and the small pockets on the hip belt on the outside. Not having a lot of pockets is good so you don't forget what is in each one.
Like being able to remove the brain from the top for trips needing less gear.

Dislikes: The hip belt is designed for comfort, however, since it's so conforming to the body shape, it's awkward to separate the hip belt apart, to put your body in between.

Incredible Backpack
Reviewed by Gary J. - January 26, 2019

Likes: The Atmos 65 is one of the top backpacks on the market period. The organization is amazing, just like the Atmos 50 but you get two front zip pockets on the 65 and those things can come in really handy. Its a great fitting pack and under load the suspension works really well.

Dislikes: None

Quality Product with great weight support
Reviewed by Walid C. - January 26, 2019

Likes: So many pockets for ease of organizing your backpacking gear. Shoulder straps are well cushioned. The mesh pocket on the front of the pack is very useful for easy to grab items, or to dry out something wet like sock or jacket...

Dislikes: Does not include a rain cover, considering the high price ticket on the backpack.

Solid Pack

First Impressions
Reviewed by Brian K. - January 1, 2019

Likes: I'm comparing my new Atmos 65 AG to a rental Kelty that I used recently so I haven't had a lot of experiences to compare to. I thought the Kelty was very nice during a three day hike in RMNP but the Atmos is far and away better than the Kelty I rented. The Atmos truly does actually hug your body and makes the load seem lighter. Beautifully designed. I am about 6'10" with 21" torso and a slim athletic build. I bought the medium after consulting the Osprey website and the medium turned out to be the correct choice.

Dislikes: None, so far.

Great pack

I wanted to NOT buy this pack.
Reviewed by Matt T. - December 17, 2018

Likes: Full Disclosure: Christmas gift and I’ll update this after real use I did not want the pack everyone raves about. I wanted something different from every other hiker out there. I shopped and shopped, they all felt the same. So I focused on pack weight and features. Reluctantly I threw on this pack to see what the fuss was about....

Dislikes: None

Loving this pack so far
Reviewed by Joseph M. - December 12, 2018

Likes: I had the Ospey Atmos 65 AG, which I absolutely loved, that I bought in 2015, and recently passed down to a friend who is just getting into backpacking. This pack seems even more comfortable. Seems like they improved the AG suspension, which I thought was amazing on the older version. All of my gear fits perfectly with room to spare. The hipbelt pockets do sit back a little far, so the zippers can take a little jiggling to get closed if you're on the move, but it's really not been an issue thus far. I will say the hipbelt pockets seem a good bit roomier than my old pack. I also like that they added a little reinforcement to the mesh pocket on the front of the pack. I haven't had the chance to put any real miles on this pack yet, but a few miles here and there over the last month have been great. I live in Colorado so hopefully i'll be able to get on a trail for a few days and nights in the next couple and really test it out. I'll also add that I'm a pretty big guy, 6'2, 280 lbs, and I can really get this pack to sit comfortably everywhere on me.

Dislikes: None so far
