Material: plastic Release Rating: 9 Boot Compatibility: touring (ISO 9523) Brake Width: 90mm, 100mm, 110mm Brakes Included: yes Balancing weight savings and performance in backcountry bindings is a never ending battle, but the Atomic Backland Summit 9 BR Binding gets awfully close to ending it forever. These bindings boast adjustable release values in both the toe and heel for added peace of mind, as well as 3-levels of heel raisers and 50mm of adjustment for use with all of our boots. The result is a lightweight binding that we know we can trust from short post work jaunts to day long missions.
