K2.1 style surfboard fins in Dual Tab Thruster with Performance HexCore CARBON base

K2.1 fins are renowned for excellent performance in hollow beach break style waves. A more 'up and down' fin, they emphasise pivot and are suited toward tight pocket surfing

base: 110mm  depth: 115mm

also available as a Quad set

Carbon base and Performance HexCore inlay for extra responsive power.

For those who surf critical, these advanced carbon fins provide a more progressive flex, starting from the stiffer carbon base and releasing through to the responsive fiberglass tip. Meaning you get the best of both worlds, with both power and flex packaged neatly together in a single dynamic fin.
