During your ascent of a multi-pitch route, the Black Diamond Rock Blitz 15 pack will be your best ally to reach the summit. Designed with recycled fabrics and a Blitz-style main opening, this 15-liter pack allows for quick access to your climbing essentials. Ideal for multi-pitch outings, the Rock Blitz 15 is designed to move with you, pitch after pitch, while carrying everything you need to reach the top.
The top closure also doubles as a rope holder once at the summit, and the side zippered pocket offers quick access to your phone, topo, or camera. This compact pack is perfect for moving quickly on big routes, while maintaining a streamlined profile. With its EVA padded shoulder straps and back panel, it ensures all-day comfort, while the sternum strap and waist belt are removable to reduce weight during fast and light ascents.
