FCS II AM Twin+1 PC Grey/Charcoal Retail Fins - Surf Derives

The FCS II AM Twin+1 PC Grey/Charcoal fins are based on the signature template of Al Merrick, designed to provide fast, smooth, and ultra-maneuverable surfing. This twin + stabilizer setup combines a powerful drive with a quick pivot capability, perfect for chaining tight turns with ease.

Thanks to their solid base and narrow tip, these fins generate excellent speed while allowing for a quick release in maneuvers. The low sweep promotes a more vertical and dynamic surf, while the slightly advanced central stabilizer enhances control and precision in turns.
