Description + Union's Ultra Snowboard Binding lives up to its name, setting us up for success anywhere we take our deck. With a stiffer medium flex comes well-blended performance that values power and response for big jumps and bigger carves. Asym baseplates set our feet naturally for comfortable riding, while its specialized design reduces vibration to lessen fatigue. And the Stage 15 Duraflex highback smoothly flexes with our boots so that we stay one with the board. union ultra snowboard binding - women's
