What Our Gearhead(R) Experts Are Saying:"I love this pack for missions where I'm moving fast but still need gear storage. It carries like a running vest but has enough space for extra layers, food, and even poles. The harness is super comfortable, and the front flask pockets make it easy to stay fueled on the move."For big alpine days when speed matters as much as storage, we turn to the Black Diamond Distance 15 Backpack. Designed with inspiration from running vests, this hybrid pack keeps weight close and stable while offering 15 liters of space for layers, food, and mountain essentials. Built with BD SETT (Stitchless Edge Taping Technology), the harness provides comfort and flexibility that reduces pressure and chafing on the shoulders. Durable UHMWPE ripstop body fabric withstands rugged alpine terrain, while custom diamond mesh adds breathability and comfort. Front flask holsters keep hydration accessible, dual side compression straps dial in the fit, and Z-Pole sleeves make carrying trekking poles simple and secure. Whether linking ridges or moving light and fast through technical terrain, the Distance 15 is built to keep up.
