Built to withstand heavyweight weekends or weeklong backpacking trips where comfort and ventilation are paramount, the Osprey Atmos AG 65 Hiking Backpack is a welcome companion to all adventures. Boasting an AntiGravity suspension, it delivers an incredible fit that seamlessly envelopes your back and hips in 3D-suspended mesh. The Fit-on-the-Fly harness and hip-belt also make for improved comfort when trekking on challenging trails. Additional functionality is provided by multiple pockets, an internal reservoir sleeve, a sleeping bag compartment, Stow-on-the-Go trekking pole attachment, and more, to ensure you are ready for every eventuality. Plus, an integrated raincover and Durable Water Repellent treatment keeps the pack and your gear dry, while compression straps help to reduce bulk so you can move and perform for longer with ease.
