Fast, flowing twin-fin drive with modern tool-free convenience. Retro performance twin in an FCS II compatible click-in system.
The 5.9" Retro performance twins deliver timeless twin-fin speed, drive, and flow, inspired by late-1970s Australian performance surfing and updated with a modern FCS II compatible tool-free click-in system.
Featuring a tall outline with a solid base, this template generates excellent down-the-line speed and controlled release through longer, drawn-out turns. The black Pro Glass fiberglass construction provides a smooth, predictable flex that loads naturally and releases cleanly—ideal for surfers who value feel over stiffness.
Designed for both retro and contemporary twin-fin surfboards, these fins excel in clean beach breaks and point waves where speed and flow are key.
