What Our Gearhead(R) Experts Are Saying:"This is the pack I grab for multi-pitch days when I need just the essentials. It rides high, so it stays out of the way while climbing, and the rope carry strap is a small but genius touch. It's lightweight, super clean, and tougher than it looks."On long routes with tight belays and complex movement, we need a pack that moves with us-not against us. The Black Diamond Rock Blitz 15 is purpose-built for on-route performance, giving us just enough space for layers, snacks, and water without ever getting in the way. Made with recycled materials and designed with Blitz-style access, this stripped-down pack is fast to open and close even with one hand. External routing for a hydration hose keeps us fueled, and the top strap doubles as a rope carry after the last pitch. From alpine rock linkups to canyon missions, the Rock Blitz is small but seriously capable.
