The FCS II JS shaper fin, developed in collaboration with Jason Stevenson, is designed for surfers seeking reliability in bigger waves while maintaining the ability to release the tail and surf progressively in smaller waves. Featuring the PC Carbon construction, it reduces weight and increases stiffness in the lower two-thirds of the fin. The carbon tissue inlay provides quicker memory recall during turns. The extra-long base delivers drive and speed, while the tapered tip allows for release at vertical angles. Suitable for intermediate and advanced surfers, this fin offers security, smooth transitions, and tail release on the open face.
