Black Diamond Rock Blitz 15 is the ultimate backpack for rock climbing. A worthy addition to any multi-pitch kit, the Rock Blitz 15 is designed to move with you pitch after pitch, carrying all the essentials to the summit. Featuring the signature Blitz-style main opening and a side zip pocket for quick on-route access to a phone, topo, or camera, this pack also has a stripped-down profile for moving fast on big lines. The top closure strap doubles as a rope carry once you summit, and external H2O hose routing gives you the option of staying hydrated on the send. The pack's EVA padded shoulder straps and back panel make for all-day comfort, while the sternum strap and waist belt are fully removable to save weight on fast and light pushes.
