From point breaks to beach breaks, you can surf it all when you have the FCS M3 Natural Glass Flex Tri Fin Set on your board. The molded composite fins have a rounded template that help you find a balance between maintaining high speeds and high maneuverability. A glass flex construction gives a stiff ride while still having adequate flex and memory. When you're surfing calls for versatility, the FCS M3 Natural Glass Flex Tri Fin Set has got you covered.

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.

Fin Specs – Base: 4.28" / Depth: 4.41" / Area: 14.22in² / Sweep: 31°

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.
