Radical in design, minimal in weight and optimized for sport climbing, the Ozone is built with Black Diamond's exclusive Kinetic Core Construction, which keeps weight and bulk at an absolute minimum (for onsights and redpoints) without sacrificing comfort and support (for taking whippers and hour-long beta dogging sessions). The bullhorn-shaped waistbelt (with pre-threaded Speed Adjust buckle) and fixed-size leg loops have a breathable wicking liner to keep you moving free and easy. Two extra-large pressure-molded gear loops comfortably hold 20-plus draws and low-profile metal buckles on the rear elastic risers allow for quick adjustment.
