This is the standart construction with the benefits of modern composite technology
all starts with an 30kg/m3 EPS core wraped in  UD carbon fibres, which are optimized
in there orientation to make a solid but flexy board structure.
On the outside we use the best Hexcel fibre glass in 45°/45° and 0°/90° orientation.
All this gives you a rock solid, light weight and still flexy board.
