The T1 Thermotech is Futures performance twin-fin designed for used in any performance twin model. Made in Huntington Beach, the Thermotech product line does not have the traditional plastic feel of a composite fin. Instead, they have a consistent flex that creates drive and release through turns. Thermotech fins come with the Futures Truss Base, making them lighter and stronger. Available as a pair, these fins are built with 4º cant angle.
