FCS Gmb Pc Tri Fin Set pattern

The GMB PC Tri Fin Set by FCS is for surfers who want the feeling of a traditional glass fin with the added performance of reduced weight. It has inside foils developed to increase fin efficiency, speed and hold through more positive water flow. Resin transfer moulding (RTM) allows the Performance Core fins to be made stiffer. Stiffer flex pattern allows you to push extremely hard through turns while the Inside Foil Technology provides increased drive.
