Engineered to redefine your line by giving you the ability to blend mountain terrain and activities, the Distance 15 is a hybrid pack that transcends barriers. By combining running-vest technology with Black Diamonds award-winning pack design, the Distance 15 moves with you while you run yet carries alpine gear with purpose-built features, so you have the gear you need when the trail ends, and the climbing begins. Built from BDs UHMWP 10x Ripstop Yarnsthe same burly material they use in their climbing dogbones and Ultralight Camalotsthe Distance fabric is literally 10-times stronger than steel per weight, while remaining so light it floats in water. The shoulder strap harness system utilizes BDs Stitch-less Edge Taping Technologymeaning the shoulder strap edge binding is fully edge taped instead of sewn, more like todays innovative sportswear then a traditional running backpackwhich allows for superior comfort, movement, and weight reduction. Also, the harness system is constructed with an adjustable, elastic-cording side compression system, which gives you a more secure ride while running, scrambling and climbing. This vest-like system also includes dual flask pockets that fit two BD HydraPak SoftFlask (sold separately) and a Deploy pocket to stash the BD Deploy Wind Shell gusty ridge traverses and emergencies. The pack portion of the Distance includes a quick Blitz-style main opening with a stash pocket to tuck away essentials, while a mesh divider wall can store cordelette or a water bladder that can integrate with the packs hose routing. On the packs exterior, the Distance 15 includes dual piolet/ice axe holsters, and dual Z-Pole quiver sleeves to stash your trekking poles when the terrain changes. Dual front stretch pockets are an extra place to stash nutrition or gear, making the Distance 8 an ultra-versatile pack for moving light and fast in the mountains.
