FCS glass flex quad set featuring the M5 fins in the side and the G1000 centers in the rear. Delivers consistent performance and long lasting durability.

The M Series shortboard fins by FCS are designed to be fast and smooth with better hold and more squirt through turns. The inside foil technology offers superior drive and the flexible tip provides forgiveness and control at high speeds.

Glass Flex has been formulated to replicate the flex and memory properties of hand layed 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.
