Thermotech fins do not have the plastic feel of a conventional injection molded fin. Instead, they have a consistent flex that creates drive and release in turns. Thermotech fins come with the Futures Truss Base, which makes them lightweight and stable. F2, F4, F6, F8 The template for this line of fins is John John's all-around favorite, the F4 template. The F2 is the extra-small size, F4 small, the F6 is the medium size and the F8 is the large size. A complete line suitable for all surfers. All Futures Thermotech fins are manufactured at the Futures factory in Huntington Beach with precision tooling and designed to feel like fiberglass fins.
