Since its introduction in 2008, the Exos Series has become a standard on the Appalachian Trail and with ultralight enthusiasts not willing to sacrifice comfort. Our AirSpeed suspension, torso-specific sizing and ergonomic design all contribute to bridge the gap between comfort, fit and light weight. The Spring 2014 redesign benefits from Ospre's never-ending search for the latest technology in materials and hardware as well as innovative design. The comfort and support of the harness and hipbelt are drastically improved. Updated materials and hardware provide a lighter weight pack, and the lid, key straps and attachment points are all removable.
