The Osprey Exos 48 is an ultralight backpack designed for experienced backpackers seeking to maximize comfort while minimizing weight. This mid-sized pack offers ample space for gear on multiday adventures where every ounce counts but comfort remains a top priority. A key feature is the AirSpeed suspension system, which ensures excellent ventilation to keep you cool and comfortable on long hikes by allowing maximum airflow between you and the pack. For a more minimalist setup, the removable floating lid can be replaced with the integrated FlapJacket to secure gear while shedding weight. Constructed from 100% recycled materials, the Exos 48 is both lightweight and eco-friendly. It includes two hipbelt pockets for convenient access to necessities and an internal hydration sleeve with a center back hose port. The adjustable Airspeed Suspension system provides 4" of torso adjustability via an injection-molded ladder system. Increased durability is offered by strong backpanel mesh and robust main body fabrics. Item Dimensions: 29.5"H x 14.2"W x 11.8"D; Item Weight: 2.77lb.
