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: * Adjustable torso
* Front pockets
* Removeable lid

Dislikes: I carry enough volume to justify this pack…

Excellent Pack
Reviewed by David B. - August 20, 2018

Likes: I bought the Atmos 65 AG in 2016, and I bought this one because of all the upgraded material and the much better color options. The only thing that would make this the best pack on the planet is if they converted the brain of the pack into the Day Lid as used on the Aether and Xenith model. It would be nice if Osprey threw in a rain jacket with an included sleeve like the Gregory Baltoro, but I guess you can do whatever you want when you’re the best supplier of backpacks in the market like Osprey. A side opening into the pack would also be a nice feature, but, with all those changes, I guess someone might as well just buy the Aether. The shoulder harness is super beefy, and this pack is extraordinarily comfortable.

Dislikes: So far, so good. I wish adjusting the shoulder harness was easier though. It’s also difficult to shove anything into the two front pockets when the pack is already stuffed. The hipbelt pockets are a hassle to zip closed after they’ve been opened.

outstanding backpack

Reviewed by Aaron J. - August 3, 2018

Likes: The suspension is top notch, so comfy! Good adjustability, h2o sleeve, nice organization, awesome hip pockets and the tuck away ice axe bungees and removable sleeping pad straps are nice details. The stow on the go pole straps are surprisingly useful as well....I had my doubts about those things but after using them on a steep rocky scramble I was convinced! The shoulder straps are a little thicker than the 2017 model which makes them even that much more luxurious!

Dislikes: The two things that I wish they would implement is a front access zipper like the old Aether packs, and more colors/multiple colorways.

Perfect for My Needs
Reviewed by Tim P. - August 2, 2018

Likes: I like the way this back pack hugs your waist firmly to take the weight off your back. I like the compartments available and the strapping on the outside of the bag (not too muck, just the right amount). This bag fits everything needed for a 2 - 6 day hike.

Dislikes: Nothing at this time but will update once I get some miles in with the bag.

Works great

Likes: Rides well on back

Dislikes: More pockets

Love this pack!
Reviewed by Anthony D. - June 24, 2018

Likes: Yes, there are lighter pack out there, but for the functionality of it, it's well worth the few extra ounces. I could certainly through hike with this pack, it's great for shorter hikes, the hydration system works well, sturdy construction. Good value for the price point. Very comfortable, the suspension system is well thought out.

Dislikes: The hip belt pockets are tough to unzip while wearing the pack, but that's my only gripe so far.
