Designed by William 'Stretch' Riedel for a wide variety of surfers and conditions, this fin features a moderate inside foil along a wide base, which generates significant speed from the initial turn, and a neutral 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 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.
