Deuter's Airlite 22 Backpack brings a seriously comfortable carry to day long hikes over tough terrain. Its Aircomfort FlexLite suspension system has a twin frame design that enhances flexibility as well as ventilation by separating the pack's load from your skin. This system also includes anatomic shoulder straps and waist belt made of 3D AirMesh padding for breathable cush. Inside the Airlite's top panel, you'll find a hydration system that's compatible with three liter reservoirs. The front stow pocket has a detachable rain cover, and there are dual waist belt pockets perfect for trail mix. Deuter also added side pockets for water bottles and compression straps for a secure load.
