The ground-breaking Osprey Atmos AG features the unique AG 3D AntiGravity floating back system, which includes a fully ventilated hipbelt. Whether you're exploring hot climates or hiking through the tundra, the seamless mesh fabric and 3D cavity back panel provide unrivalled ventilation and comfort while maintaining excellent load carrying capacity.

When fully loaded, the Atmos AG feels virtually weightless thanks to the ExoForm Biostretch harness, load carrier and fit-on-the-fly hipbelt. The InsideOut compression provides impressive load support and reduces fatigue, so you can enjoy your adventures even more intensively and for longer.

Do you need easy access to your equipment? The two zipped front pockets, bottom zip and lid access ensure you always have your gear to hand, no matter what comes your way.

The Osprey Stow-on-the-Go trekking pole attachment allows you to either stow or access your poles without having to remove the pack. A large sleeping bag base compartment with internal divider allows you to stow your gear separately if needed.

In bad weather, you can use the integrated and removable rain cover in the lid. If you want to save every last gram of weight, you can use the FlapJacket to remove the lid and still protect your equipment from the elements.
