Performance Core

Versatile RTM construction delivers a consistent feel similar to a traditional fiberglass fin, but with the advantage of reduced weight. The stiff flex pattern extends progressively from the base through to the tip helping the surfer to maintain drive and hold through a turn. PC fins are reliable, very responsive, and can be used in a variety of different conditions.
