Atmos AG 65


Product Description

The newly redesigned Osprey Atmos AG 65 Backpack features Osprey's Anti-Gravity Suspension system, so you can take your mind off your aching back and enjoy the views while you hike. The system places a continuous panel of lightweight mesh from the top of the back to the hips for a seamless design that automatically contours to your back. Not only does this make the pack more comfortable, but it increases your range of movement. On top of that, the Atmos AG has an adjustable harness system, so you can dial in the perfect fit for your individual torso size.

Built for multi-day backpacking trips, the Atmos AG 65 Backpack has everything you'd expect from serious mountain pack. An internal hydration sleeve lets you fit the pack with your favorite hydration system. A top access point makes for easy packing, while the floating lid adjusts to make room for extra gear on big trips. The lid can also be removed and used as a fanny pack for summit pushes. Two front panel pockets stash extra layers, maps, and a few snacks, while multiple gear loops allow you attach your trekking poles and ice axe.
