The Osprey Osprey Packs Exos 58 Backpack is the perfect pack for superlight backpacking and superlight thru hiking. At under 3 pounds the Exos 58 won't weigh you down while carrying all your gear and other adventure needs. Traditional top loading style with removable top pocket is great for organization. An AirSpeed SL suspension, ExoForm harness, and ExoForm hipbelt comfortably carry weight and keeps loads close to your back. AirSpeed back allows air to travel through the back panel and allow body heat out for a cooler, drier hike. An internal hydration sleeve fits most hydration reservoirs up to 3 liters to keep the extra weight up against your back and you hydrated while on the go. Ice tool loop, removable sleeping pad straps, and multiple tie-off points are great organization tools for almost anything from spill-over gear to even wet socks. Extra water in bottles can be places in the external stretch mesh pockets, or use those same pockets to keep your map, compass, head lamp, or just about any regularly needed item close at hand and easy to find. For a backpack that can carry your ultralight gear with a stable, comfortable suspension and just a bit more space the Osprey Exos 58 Backpack is up for the job!
