  • Overview

    • The MB template offers freedom to perform tight turns in the pocket with an emphasis on speed.
    • Sitting in the reactor family, the MB is considered a high-performance fin because it responds incredibly fast, but still offers enough control so you can confidently lay into a turn with plenty of force.

    Ideal Conditions

    • A wide range of conditions, particularly good in critical overhead waves.

    Board Types

    • Designed to fit the FCS II Fin System.
    • Performance shortboards and hybrid models.

    Fin Family

    • Reactor: Find Speed. Speed, tight turns & snaps.

  • Performance Core Carbon

    Often referred to as PC Carbon or PCC, these fins are highly responsive and feature strategically placed carbon that’s designed to complement the fin template. PCC fins suit fast surfing and are favoured by power surfers who like to perform explosive turns on critical parts of the wave.

      Favorite fin

      This is my favorite template, literally does everything in all conditions really well. I’ve never second guessed them from NY beachbreaks to Central America to Indo. 10/10

      Well rounded, reliable.

      These are great. They’re fast, react well but are quite well rounded. I feel I can put them in any of my boards and they’ll perform.
