This material is the reason why Glissade boards don't chatter. It is also the reason why they hold an edge better than any board out there.
Many companies use stiff, even brittle plastics that send their boards chattering down the hill.
Other companies use rubber foil to dampen vibrations along the edge. This is a good idea and we use it too. But our Vibrathane topsheet is like a huge piece of additional rubber foil that covers the entire board, except it is thicker, tougher and provides complete dampening for the entire board. Our new PolyOlliemer topsheet was created to provide extra response and snappiness for freestyle and park riding. Unlike Vibrathane, PolyOlliemer retains vibration and translates it into extra snap and energy redemned when launching off lips and jumps.
