The FCS II HS Shaper Fins by Haydenshapes were designed by Hayden Cox (Hayden Shapes) to deliver versatile, high-performance surfing with a strong focus on speed, drive, and bottom turn response.
Their all-round template with a longer base generates exceptional acceleration off the bottom turn, especially on long open-face waves, where maintaining speed and flow through maneuvers is essential.
This model is perfectly suited for the HS Hypto Krypto and other higher-volume boards with low rocker, optimizing modern progressive surfing performance.
Ideal Conditions
Recommended for a wide range of waves and conditions, delivering consistent performance in both small surf and more powerful waves.
Board Types
Designed for the FCS II Fin System, ideal for performance shortboards, higher-volume boards, and low rocker designs, where speed is key.
Fin Family: Reactor
Part of the Reactor range, built for surfers seeking maximum speed, tight turns, fast snaps, and instant response.
AirCore Technology Construction
These fins feature AirCore technology, with a pressed polyurethane foam core that replicates the fin’s geometric foil. This reduces fiberglass usage in the RTM (Resin Transfer Molding) process, making the fins much lighter while optimizing flex for improved sensitivity and performance.
Compatibility
Designed for the FCS II Fin System.
Available Sizes
- MEDIUM: 60 – 80 kg
- LARGE: 75 – 95 kg
✅ Perfect for surfers looking for speed, control, and maneuverability, especially on boards like the Hypto Krypto and in open-face wave conditions.
