Easy-to-use backcountry bindings. The BC Auto bindings have the simple button-press release system to take off without bending over. To put on, simply press your toes down to attached the binding to your NNN boot`s bar. To remove, use your ski pole to apply pressure to the top of the binding to pop it off. These bindings require screw-on mounting. If you are not comfortable mounting bindings, ask us or a local shop to do it for you! For the DIYers, pre-drill pilot holes and use waterproof glue on hole prior to screwing onto ski.
