These FCS H4 fins have been precision Swiss engineered. This is a high tech set of fins made of Performance Core and Carbon. The combination of these materials make it super strong yet lightweight. The fins are perfect when the waves are really good and they provide a fast, smooth and predictable feel.
SIDE FIN PROFILE: Lower section produces maximum acceleration, while hatchet like tip creates stability & control.
CENTRE FIN PROFILE: Highly raked elliptical outline reduces drag, and offers feeling of predictability when releasing through turns.
FIN FOILS TEMPLATE: Thicker base with tapered tip optimises flex & regulates the release of energy during rail to rial transitions.
