The F-ONE THRUSTER FIN SET surf fins have been developed to optimize the efficiency of our shapes. Their outline, stiffness, and profile were designed specifically for surfing with a kite, which means different requirements than for prone surfing. The FLOW series was developed for versatility and high performances over a wide range of conditions. Using the RTM construction paired with a carbon strip, the FINS FLOW CARBON generate more speed and deliver controlled flex and enhanced base stiffness.
