The newly released Kiri Flex TRI FINS from FCS are

We also recently received the LOST DIABLO-X and took it for a test ride on a C4.
Kiriflex uses paulownia wood from southern Kyushu as its main material, which is the lightest type of wood in Japan.
It is highly resistant to moisture, has few cracks or twists, and is highly durable.
It is also used as a stringer for surfboard blanks.

Developed through a collaboration between FCSll and Kiriflex, the fins' flex and high resilience created by the paulownia wood will enhance the resilience of not only the C4 but also other board materials!

Not only is it a fin template with an excellent balance of speed, flow and response!
It's designed with inside foil that lifts up!

-Uses Inside Foil Technology (IFT)!
-Excellent maneuverability and speed control, making it suitable for all-round use.
- The flex and high rebound provided by the Kiriflex core increases drive and hold during turns.
