FCS II Mat Biolos PC Carbon Fin

This template is designed for surfers who prioritize speed and tight, aggressive turns in the pocket. Because it belongs to the Reactor family, it is built for rapid response, making it ideal for high-performance shortboarding where you need quick directional changes.

The carbon-infused core makes these fins significantly lighter and stiffer than standard fiberglass or plastic options. This added stiffness provides a more immediate energy transfer, giving you a snappy, responsive feel when you push hard through a turn.

Yes, these are designed specifically for the FCS II fin system. They feature a tool-less design that allows you to click them in and out of your board without needing screws or a key.

This specific product is a three-fin thruster set. While the FCS II system allows for flexibility, this particular template is engineered as a tri-fin configuration to maximize the specific speed and control characteristics intended by the shaper.

While they excel in high-performance conditions, the Reactor template's focus on speed generation makes them quite versatile. They can help you generate speed in average conditions, though they truly shine when the waves have enough face to allow for aggressive, vertical surfing.
