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.
A quick note about our photos!
We use a mix of official brand images and real-life shots from our warehouse to help you make an informed decision.
That said, what you see might differ slightly from what you receive — simply because we can't photograph every possible variation.
For example, a photo might show a 6'2 board with Futures fin boxes, while you've selected a 5'10 with FCS II. Don’t worry — you’ll get exactly what you ordered.
Sometimes, small details like the logo, its placement or overall colour tones can vary slightly depending on the production batch, camera, lighting, or even your screen settings.
These are always only minor differences, and in most cases, the photos are spot on - but we totally get that buying online can feel tricky. If you ever want more details, just drop us a message — we're happy to help!
