FIN SHAPE This all-new fin design gives the board unbelievable speed and control in combination with turning ability not experienced before. Especially the cut back will blow your mind. Jason’s fins have a new outline shape, very straight with a constant rake, that challenges the performance of the traditional swept back outline. Experience from racing fins has always shown that straighter outlines are more efficient and faster. We worked with this knowledge and developed a new outline which combines performance with maneuverabilty. TECHNOLOGY G10 fins produced in high-precision CNC technologySource
