A long-time favorite among AT thru-hikers and fast-and-light backpackers, the Atmos 65 combines both durability and lightweight performance. A redesigned harness and adjustable hipbelt now provide even better comfort and fit.
Osprey's AirSpeed Suspension system equips the Atmos 65 with weight-carrying efficiency and breathability. A lightweight aluminum frame works in tandem with twin titanium struts and a tensioned backpanel to provide the ultimate in support, weight distribution, flexibility and comfort. A sliding sternum strap and load-lifter straps allow you to fine-tune fit with on-the-go adjustments. Accommodating backpackers of different heights, the Atmos 65 is available in your choice of sizes. The Medium Atmos 65 fits torsos ranging from 18"-20.5" and the Large size is designed for torso lengths that exceed 20".
To further ensure that the Atmos 65 fits like a glove, each hipbelt offers integrated adjustability that can extend the "wrap" of the supportive padding. This design allows for customized fit that ensures proper support and range of motion.
Designed to comfortably carry 35-50 pounds of gear, the Atmos 65 lends versatility for outings ranging from overnight trips to fast-moving, light-packing extended backpacking trips. The Medium size offers 3967 cubic inches of storage capacity and the Large Atmos 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 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. A pocket located inside the floating lid of the Atmos 65 provides yet another organizational option. 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 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 65 hydration compatible. Zippered mesh pockets on the hipbelt keep snacks and essential items in easy reach.
Constructed of lightweight, durable 210D high tenacity twill nylon and 100D high tenacity mini-ripstop nylon, the Osprey Atmos 65 is available in your choice of colors.

Real Customer Reviews
Likes: Pretty much everything. Accessibility. Comfort. Durability. It also just looks good.
Dislikes: Could used an integrated rain fly.
Likes: I like how you can change the height of shoulder straps, and really fit it to yourself. Enough compartments to organize stuff well but not too many. Very comfortable pack.
Dislikes: No place to put excess straps from hip belt tensioners. I have a small waist so the straps dangle below quite long though this isn't a big deal because you can tuck them under the belt... or ignore it. Also doesn't come with integrated rain cover like my other osprey pack.
Likes: Amazing pack. So many pockets and space that I didn't know where to begin when loading it up. The sleeping bag compartment is great. Lots of space inside. You can also remove or enlarge the sleeping bag compartment, as it is adjustable.
Dislikes: Long straps. Although it is a large bag, it is a narrow fit. Those are the only bad things I have to say.
Likes: Great Backpack and product
Dislikes: There nothing to dislike Osprey 65 Atmost!
Likes: The best pack that I have bought. Ultra lightweight with plenty of storage capacity. I know how much I have appreciated from my first 50 mile trek. Shipping from Country Edge was super fast.
Likes: LOVE IT. Getting ready to take it out for a 3-nighter soon. Love the light weight and the fact that it's an Osprey (they're awesome).
Dislikes: Nothing so far
Likes: As with all Osprey packs: great design, comfort, and quality materials/build. I know its not the lightest around but this thing can carry a ton of gear. Very comfortable and does an excellent job of distributing the weight. Great for extended/cold weather treks.
Dislikes: Nothing, a great pack for when carrying a heavy load.
Likes: Very light weight for a pack that provides a sufficient number of compartments. These were well laid out and helped to keep gear organized and of easily accessible.
Dislikes: The waste belt was only adjustable to a point. After losing a considerable amount of weight on a thru-hike I ran out of adjustability. Other Osprey packs (eg. Aether) replacement belts of varying sizes. This isn't a problem for most hikers.
Likes: I already had the Atmos 50 but bought the 65 for the extra space. The sleeping bag compartment is a great added feature. It fits both my sleeping pad and sleeping bag so I no longer have to unpack everything to setup camp.
The suspension is great and the airflow mesh really does the job of keeping my back dry while hiking.
There are plenty of pockets for compartmentalizing everything and the tool straps fit my axe like a charm.
Would definitely recommend.
Dislikes: I wish this bag had side access zippers
Likes: Been a fan of Osprey packs for years and have been using the 50L version of this pack for longer day hikes when I bring my camera, extra lenses, and tripod. Finally decided it was time to add to the line with the 65L for overnights or when I need a bit of extra gear. Weight distribution is fantastic and I find this pack to feel comfortable and stable no matter how much I pack in it. It has multiple organizational options which I love. The material is strong but flexible and it has all sorts of adjustments for a great fit. Great pack! And the lifetime warranty is an added benefit.
Dislikes: Nothing. I love everything about the Osprey Atmos
