The Thermotech Side Bite will add stability to your longboard, improving drive and hold on the face of the wave. Made in Huntington Beach, Thermotech fins do 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.
