Made for fast and light mountain missions Black Diamond's Distance 15 Backpack is a hybrid pack that combines an alpine-worthy daypack with shoulder straps similar to running vests. We love that the shoulder harness utilizes Black Diamond's stitch-less Edge Taping Technology to eliminate chafing while the ventilating back panel keeps our back cooler and our load close to body for scrambling and running technical ridgelines. Plus external gear attachments and easily accessible stretch pockets keep our ice tools trekking poles devices and snacks at hand.
