Efficiency, Meet Power! The Switchback X2, same reliable ice-proof latching system for efficient uphill travel, but with new more powerful downhill toe plate and stiffer cartridge springs. Voile lengthened the toe plate by almost 3cm, repositioning the Hardwire cable pivot point and stiffened the cartridge springs by 25%. All these improvements and these are still the lightest telemark touring binding at 3lbs 2oz./pair!! A free-pivoting, alpine touring-style telemark binding, the new Voile Switchback X2 allows backcountry telemark skiers to ascend with zero heel resistance thus conserving valuable energy and allowing for easier trail breaking. The Switchback X2 is easily switched from uphill touring to downhill telemark skiing with use of your ski pole. Also, it comes standard equipped with dual height climbing heel elevators for varying ascents.
