    UNIQUE TEMPLATE

    Radically different side & center fin templates create a powerful fin set with ultimate speed & drive.

    • Side Fin Profile: Lower section produces maximum acceleration, while hatchet like tip creates stability & control.
    • Center Fin Profile: Highly raked elliptical outline reduces drag, and offers feeling of predictability when releasing through turns.
    • Fin Foils Template: Thicker base with tapered tip optimizes flex & regulates the release of energy during rail to rail transitions.

    Ideal Conditions

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

    Tech as feel

    Dope new design. Goes well in a few different boards. Particularly loves it when it’s overhead with plenty of push.

    H4 Tri Medium Fins

    Unique shaped fins that are finished beautifully. I enjoyed how light the fins are, yet are incredibly strong and stiff. The fins are responsive and create super speed and drive out of turns. This is the best set of fins I have used in 26 years. In fact, they've given me so much stoke, that I have purchased a second set, to enjoy the medium and large sizes for different size surf.
