The F4 Thermotech is a small sized thruster in the Neutral template category. 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.
