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 zippered 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 unzip 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.

Real Customer Reviews
- New backpacker
Likes: The osprey atmos was awesome. Just finished a trip with my sons Boy Scout troop and I had my gear and half of my sons gear (his pack is just too small since he is little) and it was great. I think the mesh backing that creates a separation from the pack was key in my purchase. I live in southern Az and sweating happens just walking outside. So having that separation so that air can get to my back was a great feature.
Dislikes: Nothing really. The belt pouches are a little small and the zippers are a little hard to open but not worth changing my mind about how great this pack is.
- Outstanding backpack
Likes: Exceptional comfort in the waist and shoulder pads. I've tested other packs and no other pack comes close in terms of comfort. It held up very well with 35lbs of gear. Also lifetime warranty by manufacturer is a big plus.
Dislikes: Back mesh does not look very durable, however did not have issues in the field.
- Awesome pack
Likes: Comfortable, light, and well built. The trampoline suspension really keeps your back nice and cool
Dislikes: The hip straps actually take up a lot of space, as they don't really fold flat against the pack. Makes it a little hard to prop the pack up on the ground, and it's a little tricky to put on.
- Best overall pack
Likes: Extremely comfortable, good size for 4-5 nights.
Likes: Large and spacious. Comfortable. The dark green color looks beautiful. Can put a lot in here without straining your back. Many compartments for organization.
Dislikes: None. This backpack is incredible. A lot of straps and adjustments to get used to, but this is not really a con.
- What I have come to expect.
Likes: The Atmos is a great, durable and accessible pack. Just used it to hike into a base camp to summit a 14er in CO. I was able to fit all my gear for a 4 night stay.
Dislikes: I think that my dislikes have to do with my body shape. I have a super short torso so it is hard to get the pack to put the majority of the weight on my hips. Does anyone have a suggestion of what kind of pack I should consider for my short torso???
- Comfy with tons of room.
Likes: Love the comfort of this bag. Pockets are roomy and well thought out. access points galore. The adjustments are many for a bag this size.
Dislikes: Would like to see more fasten points on the top and back of this bag but otherwsie very happy with it.
- Excellent pack
Likes: Air between pack and your back, really redistributed the weight, hip belt pockets
- Great pack lacking complete back support
Likes: Tons of storage, easy access, double pocket brain, great size sleeping bag compartment, comfortable hip belt with adjustments, carries good size load, easy to adjust anti gravity suspension
Dislikes: Mesh back support is not complete. Feels great around the hips and lower back, but felt like there was no mid back support and the anti gravity adjustment was uncomfortable across my upper back. Also, I feel like the mesh backing started to stretch out the more I used it providing less support over time.
- I have been a fan of the Atmos for years now with the exception the fit is a little tricky for broad-shouldered athletically muscular frames.
Likes: Easily adjustable, expandable hip belt, larger hip belt pockets that are actually useful on the medium pack unlike previously only large had ample space, removable brain, breathable, front-facing water bottle pocket option though I didn't try this feature on recent trip
Dislikes: Tricky fit for me (5'9" 176 pounds) Belt sometimes slips in Velcro, brain can get in way of head mobility when looking up while climbing in steep terrain or class 3/4 rock, shoulder atraps no longer interchangeable
