Product Info

The Reactor Fin Family is all about speed and agility. When paired with a Performance Carbon Core in the FCS II Reactor PC Carbon Large Tri Fin Set, what you get is a super dynamic fin ready to slash and pivot with ease.

Product Details


Performance Core CarbonDynamic 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.

AirCoreFins with AirCore Technology feature a pressed polyurethane foam core that mimics the geometric foil of the fin. AirCore technology reduces the amount of fiberglass required in the RTM moulding process making it much lighter while allowing total manipulation of the flex.
