Overview

UNIQUE TEMPLATE

Radically different side & centre 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.
- CENTRE 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 optimises flex & regulates the release of energy during rail to rial transitions.
Ideal Conditions
- A wide range of conditions, particularly good in critical overhead waves.
Board Types

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.

Superlative speed

Nothing about the design of these fins has been overlooked, the material is of a very high quality and the design seems to have been developed by NASA. Speed and control!!!
