Split Pin System – By combining the standard pin system with the Split System baseplate, Union increases the amount of connection between board and binding. Just one pin changes the mode and locks it into place.

Touring Mode – For touring, the binding slides into the climbing cradle and is locked into place with the pin.

Riding Mode – For riding, the binding slides onto the baseplate which rotates over the center of the board. The pin slides the through the middle of the baseplate for maximum connection.

Split Disk – Compatible with Voile pattern and 4x2 DIY.

Quick FLAD and Ladder – When it's time to switch your bindings to climb mode, the most comfortable option is lowering your forward lean adjuster to decrease the highback angle for the ascent. Featuring just a one-turn adjuster and quick flip ladder these changes happen with minimal effort.
