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 Black Diamond's signature Blitz-style main opening and a side zip pocket for quick on-route access to a guidebook, phone or camera â€" 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 allows you to stay hydrated. The backpack's EVA padded shoulder straps and back panel ensure all-day comfort, while the sternum strap and waist belt are fully removable to save weight on fast and light pushes.
