Osprey Packs Exos 38L Backpack Blue Ribbon, L/XL

Osprey created the Exos 38 Backpack with a lightweight yet sturdy aluminum frame and the ultralight AirSpeed suspension system so we can transfer slightly larger loads than other minimalist packs. The mesh back panel and ExoForm harness provide comfort under the straps and help circulate air to improve evaporative cooling, so we can comfortably spend extended periods of time with the pack on.
