Futures Fins K2 Fibreglass Keel Twin Fin - Black/Grey

The k2 fiberglass keel twin fin is a smaller, more refined version of the traditional keel fin.
Availability: In stock

The k2 fiberglass keel fin is a smaller, more refined version compared to our traditional keel fin. The k2 keel’s fiberglass material offer minimal flexibility and maximum stability while the smaller template gives this fin a more high performance feel while maintaining the classic keel fin ride.

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

Flat foil: 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.
