The most responsive JS fin ever! Thanks to an updated construction, the JS signature fin is now lighter with even more drive and control. This fin set is best suited for intermediate and above surfers, with an emphasis on open face surfing with power. It can still be used for technical surfing when needed thanks to it's a tapered and narrowed tip which allows the fin to release out of the lip when pushed hard on more vertical angles of attack.

“The best surfers in the world have used this fin to win multiple events, so we know it works.” - Jason Stevenson
