6" MR '78 Twin Fins – FCS II compatible orange on white on black Pro Glass (2 fins)

Fast, flowing twin-fin drive with modern tool-free convenience. MR ‘78 twin in an FCS II compatible click-in system.

The 6" MR ‘78 twins deliver timeless twin-fin speed, drive, and flow, inspired by late-1970s Australian performance surfing and updated with a modern FCSII 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 colourful 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.
