Blurring the line between running and ridge scrambling, the Black Diamond Distance 15 Backpack is a hybrid pack that combines an alpine-worthy daypack with shoulder straps similar to running vests. There are two pockets for soft flasks, two smaller pockets for nutrition, and another zippered pocket for keys or cash. The shoulder straps utilize Black Diamond's stitch-less Edge Taping Technology to eliminate chafing and promote ventilation, while the back panel also ventilates, wicks moisture, and dries quickly for active comfort high up in the mountains.
