3.6" + 7" 2+1 Fin Set – Natural Pro Glass | FCS Compatible Side Fins (Set of 3)

The 3.6" + 7" 2+1 Fin Set delivers the timeless balance of drive, hold, and flow that defines the classic 2+1 surfboard setup. Featuring a 7" centre fin paired with 3.6" side fins, this configuration offers excellent trim speed, smooth rail-to-rail transitions, and dependable control when stepping forward or carving off the tail.
