These FCS GL Fins work great as trailing fins for a quad setup or sidebites for a longboard. These Are constructed from FCS glass flex material.

Glass Flex

Glass Flex has been formulated to replicate the flex and memory properties of laminated fiberglass. Its advantages over other composite fin materials inlcude 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.
