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

Real Customer Reviews
- an amazing backpack
Likes: good ventilation keeps the body cool, the anti-gravity suspension makes a huge difference
- Great fit, super comfy, excellent support but will it last?
Likes: This review is for both the Aura(F) and the Atmos(M): The Anti-Gravity system does work like wonders. It's super comfy and forms to your back and hips. It's ventilated in such a way that the mesh keeps the nylon material away from adhering to your back. The empty pack is relatively light in weight and has enough compartments making organization easy.
Dislikes: One thing that concerns me is the elastic mesh. Anything elastic will age and for a pack this expensive, I'd like it to last at least 5-10 years. Since the Anti-Gravity relies heavily on this elastic mesh, it loses it's selling point if the mesh ever ages. It's hard stitched into the backpack making it impossible to replace if needed. As I can't attest to the longevity of the pack, I'm knocking off one star since I'm 100% sure elastics age over time and the lack of options for future replacement makes it such that you have to buy a brand new backpack when that happens.
- Truly amazing pack
Likes: Osprey's Anti-Gravity harness system is the most comfortable thing I've ever experienced in backpacking. The entire bag hugs you and nearly eliminates any pressure points without compromising responsiveness. The 65L is a sweet spot for anything from a quick overnight trip to a long thru hike. The removable brain is a nice touch as it effectively takes a large pack and shrinks it down, for those shorter trips. The compression straps and hooks are dialed for functionality. This is a very well thought-out bag.
Dislikes: I can't find anything about this bag yet that actually bothers me. It still feels like the perfect pack.
- This is my 3rd Osprey pack, so as you can see, I am already a fan. I have 2 of the Exos series packs and love them both for all season backpacking. I needed something to carry more gear and this pack is awesome!
Likes: Easy load carrying, quality pack, adjustable for perfect fit, suspension system is spot on
Dislikes: No rain cover included
- Great pack
Likes: Ergonomic, good weight distribution, cool on the back with airflow on the lumbar
Dislikes: Nothing yet.
- Excellent pack
Likes: By far the best pack I have ever had. Anti-gravity suspension, ventilation is great. Excellent comfort, makes it easier to carry a heavier load.
Dislikes: Not much to complain about, but the removeable lid was not easily removed and reattached. I wish there it had a clip.
- Big pack, best suspension on the market
Likes: The osprey atoms 65 adjustable suspension is the most versatile on the market, very adjustable, extremely well ventilated. Awesome pack at great price and excellent warranty.
Dislikes: Wish rain cover, hydration bladder and removable day pack were included with pack.
- Luxurious pack for multi day backpacking
Likes: I wanted a pack with an adjustable torso length, adjustable hip belt, under 5 lbs, and with a carrying capacity range of 30-50 lbs. There are not many packs that meet those specifications, but this pack qualified. What sold me on this pack versus the others was the anti-gravity suspension. It hugs your back and moves with you. It also has multiple compartments for organization.
Dislikes: The top brain can be removed, but does not convert into a day/summit pack. Weight could be saved if the sleeping bag compartment separator was used as the top flap when the brain is removed. Gregory packs with an adjustable hip belt allow the hip belt pockets to move with the adjustment, while this pack’s hip belt pockets will always be fixed in the same place. Some type of loop attachments on the floating brain would be nice so you could strap a bear can or something else like that to the top of the pack.
- Awesome Pack!
Likes: Feature rich and large enough for any adventure
Dislikes: Sternum strap difficult to adjust
- The only pack you need!
Likes: The suspension system is fantastic! Zippered pockets on waist belt. Easy to get to water bottle pockets. Trekking pole carriers. Hydration compatible. Head of the pack is removable.
