Performance Core
Performance Core (PC) fins are made using a multi-layered resin transfer molding process. The flex pattern in PC fins extends progressively from the base through to the tip, helping the surfer to maintain drive and hold through a turn. This versatile fin material is light, and can be used in a variety of different conditions.

The fins are great they make my board Pro-form well and help me with my surfing😎
It's been my favorite fins so far. I've used it in all conditions and it feels great under my boards. I've tried them on my Seaside and Evo. Both boards are totally different but I feel like it brings my Seaside to life. I can generate spend in the pocket and come off the lip with ease. I even popped a lil air off the foam. Highly recommend getting a set.
My favourite fins, really helpful customer service and fast shipping. These fins glide through the water with choice of tri or quad.
