Ventilation and comfort in 3D. The ground-breaking new Atmos AG is equipped with our unique suspended AG AntiGravity™ backsystem which incorporates the world's first fully ventilated hipbelt. Whether you're exploring hot climates or trekking through tundra, the seamless mesh and 3D cavity backpanel equals unrivalled ventilation and comfort whilst providing excellent load carrying performance. Fill the Atmos AG to the max and it'll feel practically weightless on your back, thanks to the ExoForm™ Biostretch™ harness, load lifter bar and the Fit-on-the-Fly™ hipbelt. InsideOut™ compression provides impressive load support, reducing fatigue so you can push your adventures harder and longer. Need easy access to your gear? The twin zippered front pockets, base zip and top-lid entry points mean that no matter what you're faced with, you can easily grab your kit. Our Osprey Stow-on-the-Go™ trekking pole attachment allows you to either stow or access your poles without removing your pack. A large sleeping bag base compartment with internal divider allows you to store your gear separately when required. When the weather turns for the worst deploy the integrated & detachable raincover contained within the lid. If you're looking to cut weight to the last gram then the FlapJacket™ means you can remove the lid and still keep your gear protected from the elements.
