The GNU "Hyak" is an all-terrain directional twin built for riding everything. This board features Banana Technology which means the camber is rocker in the middle with mild camber under your feet for an easier ride. Magne-Traction edges provide great edge hold on harder snow and ice. We have the Hyak in three wide sizes (160W, 163W, and 165W) for taller riders with bigger feet. Get weird with GNU!
