    Performance Glass (PG) fins are machine-cut from layers of solid fiberglass. These fins are stiff and are widely used by pro-level surfers because the integrity of the flex is maintained under immense force, and in the most extreme of conditions and situations.

    FCS Fins / Fish

    I tried my new fins for the first time yesterday on my new Fish and it was a whole different experience. I have always ridden tri fin set up boards and it was time to try something different. It took a few waves to get used to the new board and fin set up. By the end of the session, I was learning how to maneuver between my rails and make solid turns both front and backside with ease.

    Super fun

    I put them in a lost puddle jumper, gives the board ton of drive, full lay rail turns yet still allows the tail to release when you want it. Gave me more confidence to surf the board a bit harder. I think it’s a perfect blend of a fish type feel with a little more aggressive abilities! Went better on a slower reef break feels a little too on rails for a beach break though!

    Grippy carvers

    Plenty of grip on the take off drop bottom turns with this design whilst not comprising speed when you're hot-dogging to make a section and it also gives you some sweet power when slices up fat faces
