Performance Core
Performance Core (PC) fins are made using a multi-layered resin transfer molding process. The flex pattern in PC fins extends progressively from the base through to the tip, helping the surfer to maintain drive and hold through a turn. This versatile fin material is light, and can be used in a variety of different conditions.
