A triple base board is flat between the bindings and along the middle towards the nose and tail. Along the edges of the nose -and tail sections the base is lifted from 0° to max 3.5°. The base angle is greatest where the nose and tail are widest. So then you have only 40% edge contact when riding flat (when you hardly need any) and full edge contact in turns (when you actually need it). But Triple Base Technology™ has a lot more to it... like sticking more jumps.
