What material is this fin made of?

Performance Glass (PG): For decades, solid fibreglass fins have been the preferred construction for many of the world’s best surfers. Performance Glass fins are CNC machine-cut from layered sheets of fibreglass and resin, producing highly accurate foils that are then hand-finished for precision and performance.

This construction creates a stiff, dependable flex pattern that maintains its integrity even under immense pressure, making PG fins ideal for powerful surfing. The result is a fin that delivers instant response, strong drive, and exceptional control when you push your board to its limits.
