FCS II H4 Quad Rear Fins look and surf different to any other fin. Precision Swiss engineering matched with a highly evolved template provides an unprecedented level of control and predictability at high speeds.
This set comes equipped with 2 x Quad Rear Fins, designed to work with both medium & large H4 sets.
While the science behind the template, materials & foils are highly complex. Every component of this fin has been engineered to create a simple synergy between the fin & the surfboard, the rider & the wave.
