FCS II Performer Glass Flex Fin

Glass Flex is made from an engineering-grade polymer that offers a more forgiving, flexible feel. This makes it easier to initiate turns and maintain control, which is ideal if you are still learning to master maneuvers or surfing in smaller, weaker waves.

These fins are designed specifically for the FCS II fin system, which allows for tool-less installation. If your board has FCS II boxes, they will click right in; if you are using original FCS dual-tab plugs, you will need to use screws to secure them.

Inside Foil Technology (IFT) adds a slight concave curve to the inside face of the fin. This design helps smooth out water flow, which reduces drag and provides a more responsive, fluid feel when you are transitioning between turns.

The Performer Glass Flex set is optimized for riders weighing between 120 and 175 lbs. If you fall outside of this weight range, you may find the flex pattern too soft or too stiff, which can negatively impact the board's performance.

Yes, the Performer template is designed for versatility. It balances speed, flow, and response, making it a reliable choice for a wide variety of conditions, from beach breaks to point breaks.
