One of the most simple telemark bindings on the planet. The Heavy-Duty Mountaineer 3-pin is a solid light touring telemark binding. Made of the same manufacturing tools as our 3-pin Cable. It has a 3-pin bail height to accommodate a 13-19mm thick duckbill telemark boot. You can use this binding with virtually all telemark boots available. Mostly suited for mid-range to light duty boots.
