Fine tuned for performance, the Futures K2 Fiberglass Twin Fins provide more maneuverability than the K1 or Rasta Twin. The K2 Fiberglass Fn is a smaller, more refined version compared to our traditional K1 fin. The K2’s fiberglass material offers minimal flexibility and maximum stability while the smaller template gives this fin a more high performance feel while maintaining the classic Keel fin ride. Carve a timeless line sprinkled with modern style on the K2 Twin.


Fiberglass is stiff and tough for heavy conditions or surfers that appreciate very stiff fins.


Flat foiled fins break free sooner, and are better at controlling speed. Often surfers prefer them in fast powerful surf where they do not need to create additional speed. If you have muscle memory from riding glass-ons, flat foiled fins will feel the closest.
