Dependable performance in all conditions. The FCS SF4 Glass Flex Quad Fin Set is a no frills quad set for bigger riders.
Glass Flex – Glass Flex has been formulated to replicate the flex and memory properties of hand laid fiberglass. Its advantages over other composite fin materials include stiffness, a more positive flex pattern (nice tip flex, little base flex) and remarkable flex memory. The precision of the injection molding process ensures the highest accuracy in geometry in each fin produced.
Front Fins – Base: 4.48" / Depth: 4.48" / Area: 15.15 in² / Sweep: 30.7°
Rear Fins – Base: 3.88" / Depth: 3.80" / Area: 11.22 in² / Sweep: 30.7°
Front Fins - Inside Foil Technology (IFT) – A sophisticated hydrodynamic foil consisting of a convex outside face, a rounded leading edge and a concaved inside face. Inside foil increases the efficiency of water flow over the surface of the fin adding lift and reducing drag. The result is a fin with more options through increased hold and speed.
Rear Fins - 50/50 Foil – A symmetrical foil where both sides are convex. Even water flow on both sides creates stability and control.
