For weekends backpacking and lighter-weight multiday-overnight trips where comfort and ventilation are paramount, the Osprey Atmos AG 50 is an ideal choice. Its AntiGravity suspension system delivers a weight-defying fit, seamlessly enveloping your back and hips in 3D-suspended mesh for exceptional comfort. The pack features easy-to-use stretch mesh side pockets for water bottles, an internal reservoir sleeve for hydration options, and a Stow-on-the-Go trekking pole attachment for convenience. An integrated raincover keeps your gear dry in case of inclement weather. This world-class backpacking pack is made with 100% recycled materials. The Fit-on-the-Fly harness and hipbelt allow for improved comfort and a fine-tuned fit adjustable on the trail. Revolutionary AG system seamlessly extends the tensioned backpanel into the hipbelt for lightweight support. Curved zip access on each side panel, a floating top lid with lash points, and a fabric-reinforced front shove-it pocket provide easy-access storage. A zippered sleeping bag compartment with a removable divider and removable sleeping pad straps ensure your sleep system stays secure.
