FCS SF4 Stretch Quad Fin Set

Designed by Bill "Stretch" Riedel. Features a moderate inside foil along a wide base which generates significant speed from the initial turn, and a nuetral foil along a thin, flat tip. At low speeds, the ample surface area in the tip provides power, giving you the ability to generate speed with ease.

Glass Flex:

Glass Flex is formulated to replicate the flex and memory properties of laminated fiberglass. It offers the flex pattern modeled of a hand-foiled fiberglass fin and the ability to mold highly technical computer generated foils accurately.
