Mick Fanning"s signature MF-2 features the same construction, foil and outline as the MF-1 but on a smaller template. This medium size fin has a dynamic flex, is ideal for long arc turns, and is designed for high performance power surfing.Performance Core (PC) construction produces a lightweight fin with a stiff base and responsive tip flex. This translates into immediate start-up acceleration and a direct transfer of energy from the surfer to the fin.The MF-1 also features TRICOIL technology. This dynamic flex pattern is achieved through the multi-axial carbon frame inside the fin. Tricoil flex effectively stores and releases energy as the surfer transitions from one turn into the next.
