The F4 Techflex is available in Fluro Yellow (as seen here) or in Blue Hex, Clear Glass, and Natural Composite (all available in the PureGlass Online Store).  Techflex RTM combines various processing techniques to produce a strategically designed flex structure, created by a crescent shaped, carbon leading edge fin. The inlay of the two materials creates a torsional flex pattern for storing potential energy and releasing kinetic energy into whip-like turns. Light and strong, this highly designed fin has a patterned flex rebound to take your surfing to its full potential. Constantly pushing the envelope of what a fin should be and do.
