Lock into action-packed maneuvers with the FCS II MB PC Carbon Large Tri Fin Set. Preferred by larger riders, the MB PC Carbon Large Fins are scaled up from the MB Medium and cater to full-fledged power surfing. A versatile all-around template designed by iconic shaper Matt Biolos, the MB PC Carbon Fins feel reliable on the open face or tucked tight in the pocket. Performance Core Carbon construction has increased flex for more forgiveness allowing for pushing hard through turns, hacks and clean speeding through overhead barrels. Slip into precarious positions with ease on the FCS II MB PC Carbon Fins.


Dynamic RTM construction with strategically placed carbon compliments the template and sweep angle of the fin, and produce a bespoke flex pattern with remarkable memory properties. In the water, this translates to immediate response when loading up the fins and driving through turns. PCC fins suit fast surfing and are favored by power surfers who like to perform explosive turns on critical parts of the wave.
