One-Pound-Each. Here is your lightest-weight backcountry touring binding from G3. The Ion LT 12 is sleek as ever, as G3 removed the brake but kept the 5-12 DIN range on its massively popular Ion binding. To further shave weight, the Boot Stop and heel rest from the original has been minimized. The pair comes with two coiled, cabled leashes that can be used with any boot. The Ion is popular for its light weight and intuitive use that lets you power up then charge the descent. Gram counters rejoice!
