The FCS II JS PC Tri Fins are designed in collaboration with world-renowned shaper Jason Stevenson of JS Surfboards, offering a smooth, controlled feel with a strong focus on flow and drive. Stevenson describes the design as fast, fluid, and responsive, with the ability to push harder when needed while still maintaining reliable release, making these fins a dependable choice for surfers seeking both performance and consistency. Ideal for open-face, down-the-line waves, these fins excel particularly well in point and reef break conditions where long, powerful lines and speed generation are key. Made for surfers who ride performance boards with deep concaves and moderate-to-extreme rocker, this fin set integrates seamlessly with the FCS II Fin System for secure fit and easy installation. Part of the Carver family, the JS PC Tri Fins are tailored for powerful, drawn-out turns that offer added hold and stability, helping surfers maintain control while still unlocking speed and smooth transitions down the line. Whether you’re carving long arcs or pushing into faster sections, these fins deliver a dependable feel that supports a confident, performance-driven ride.
