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: 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.

Excellent Backpack

Likes: About two years ago I have purchase an Osprey Manta 36 AG which seems like a smaller version of the Atmos 65 AG. I was very impressed by Osprey's quality of the product, craftsmanship, looks and overall functionality, not mention to AG design. I have used my Manta on a countless long distance day hikes.
Based on my experience, without any hesitation I decided to purchase the Atmos 65 AG which will I plan to take on a few multiday hikes this Summer.
Again, I am very impressed with the materials used for this pack, quality workmanship and the AG concept. I am vey excited about my new pack and can not wait to take it on the trails. Will be glad to share my experiences and observations after the trail test

Dislikes: Not so far

Great Backpack
Reviewed by Robert - June 3, 2018

Likes: I just returned from a 3 day, 40 mile hiking trip at Isle Royale NP. This was my first backpacking experience, and overall I was very happy with my Osprey Atmos 65L. The multitude of compartments to store all of my belongings as well as each particular location allowed for fairly equal distribution of weight throughout my pack load. The ability to easily remove the top lid to take into my tent overnight worked out great as well. The material appears of very durable quality. I can see this item lasting a long time.

Dislikes: My only complaint is that although the zippers all appear very durable, I often found it difficult to close them on my hip belt with one hand. I found myself using both hands to close the zippers securely. I will trade the presumed long durability of the zippers for a little difficulty in closing them, however. My pack weight load was approximately 40 lbs, including hydration. My back/shoulders would get sore during the course of the trip each day. To help provide temporary relief while on the trails, I would often pick up on my hip belt for several seconds at a time to relieve the weight from my shoulders/back. Not necessarily a dislike, but just thought it was worth mentioning. I imagine anyone who was carrying a 40 lb. pack would find some occasional discomfort after long periods of time, particularly if your body was not used to it.

Another Excellent Osprey Pack
Reviewed by Greg M. - May 25, 2018

Likes: I haven't gotten this pack on the trail yet, so these are just initial impressions. That said, I don't expect anything to change. Osprey makes awesome packs, this is no different.

I've been using a lightweight (sub 3 lbs) pack for my backpacking trips the last couple years. My total pack weight normally sits between 25 and 30 lbs, and while that pack had done the job, I found myself wanting a more robust carrying system, better back ventilation, and slightly more organization options. This is exactly what I wanted.

If I carry this without the removable lid, it's just about a pound heavier than my previous pack. But the suspension system is so much better, I expect it to carry lighter, and that's exactly what I was looking for. Back ventilation is as good as it gets with the mesh, and the pack feels perfectly connected to your back. The carrying system here really is awesome. Organization is perfect for me - all the access at camp only items in the main compartment, 2 outer pockets for items I want to access while hiking, and the outer mesh pocket for a rain jacket. Hip and side pockets are good as well. No more and no less than I want.

Dislikes: Don't really have any at the moment. This is obviously one of if not the most popular pack out there, and for good reason. Robust and durable pack that doesn't go overboard on weight and extra, unnecessary features.

Very Comfortable
