Maximum drive and hold for committed twin-fin surfing.
Midnight purple Pro Glass construction delivers strength, control, and smooth projection through turns.
The 5.5" Power Twin Fin Set is built for surfers who want strong acceleration, confident rail hold, and clean projection from a traditional twin-fin platform. Constructed in durable midnight purple Pro Glass, these fins provide a controlled flex pattern that favours stability and smooth power transfer rather than excessive looseness.
The fuller Power Twin template increases surface area for reliable drive and hold, helping maintain speed through longer arcs and drawn-out carves. This makes the set particularly well suited to modern twin-fin boards, performance fish shapes, and hybrids where control and projection are essential.
Designed for FCS II fin box systems, the fins install securely and deliver consistent performance across a wide range of wave conditions.
