Universal GFN Surficata FCS II fins (Medium 4.5″) – a durable set for river surf, wave pools, and ocean riding. Stability, control, and reliable performance for all wave types.
These medium-size fins are designed for surfers seeking dependable performance with FCS II boxes. The GFN composite (glass-filled nylon) offers an excellent balance of stiffness and flex, perfect for standing waves and ocean conditions. The hydrodynamic shape ensures stability and precise board control, even under heavy river impacts.
Is this the right size for me?
Small fins (S) are playful and great for tricks, while Medium (M) is a versatile all-rounder. If you want more stability and aggressive carving, choose L. On Prague’s Štvanice wave, most surfers ride S and M sizes.
