Fins FCSII quad rear PC Reactor Haydenshapes White

The FCS II Haydenshapes Shaper Quad fins (2 fins) were designed by Hayden Cox (Hayden Shapes) to complete the 5-fin set, delivering explosive performance focused on maximum speed and fast response during powerful maneuvers.

They are highly recommended for the HS Hypto Krypto and other higher volume boards with low rocker, where their design provides better acceleration and smoother surfing.

Thanks to their balanced template and performance-driven design, these fins deliver exceptional speed out of the bottom turn, performing incredibly well on long open-face waves, where drive and projection are key.

Ideal Conditions

Perfect for a wide range of waves and conditions, offering consistent performance in both mellow and powerful sessions.

Board Types

Designed to fit the FCS II Fin System, recommended for performance shortboards and boards with medium-to-high volume and low rocker.

Fin Family: Reactor

Part of the Reactor range, built for surfers who want speed, tight turns, fast snaps, and instant response.

AirCore Technology Construction

These fins feature AirCore Technology, with a pressed polyurethane foam core that mimics the fin’s geometric foil. This reduces the amount of fiberglass needed in the RTM process, making the fins much lighter and allowing optimized flex, improving sensitivity and control.

Available Sizes

• MEDIUM: 60 kg – 80 kg
• LARGE: 75 kg – 95 kg

✅ Perfect for surfers looking for maximum speed, control, and maneuverability, especially on higher volume boards and long open-face waves.
