The Osprey Atmos AG 50 Backpack will get you where you want to be, without your back aching every inch of the way. Now featuring Osprey's Anti-Gravity suspension system, this award-winning pack is even more comfortable than before. You might be thinking an Anti-Gravity system sounds like it belongs on a spaceship rather than a backpack, but really the system is pretty simple and is composed of a single lightweight mesh panel that extends from the top of the back to the hip. This seamless design allows the panel to automatically contour to the shape of your back, while also allowing air to pass between your back and pack for a cool and comfortable fit.
An adjustable torso length along with an adjustable hip belt allows you to further customize the pack for your hiking comfort. Fully equipped for full days on the trail, the Atmos comes standard with a removable/floating lid that doubles as day or summit hip pack. An internal hydration sleeve lets you equip the pack with the hydration system of your choice, while two stretch side pockets can be used to stash gear or water bottles. Two front panel pockets are an ideal spot to stow maps, extra layers, and snacks, and multiple gear loops on the front of the back allow you to attach your ice axe and trekking poles.
