Oukai 130 L and 90 L inflatable foil board A smart compact foil board that is easy to take with you everywhere. Twin track mounting system which is a robust mounting system that is leading within the standard of leading foil brands. The area where the foil sits on the board is hard foam from the bottom to the top of the board, so it is rigid like a fiberglass/carbon board, but can be packed together, like an inflatable board. This means the board is soft to fall on, rarely gets holes, and is very easy to travel with.
