F4 Thermotech Thruster Small 40" It's a performance twin riddenThe 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. Template Category Neutral (all around versatile) Construction Thermotech Suggested Wave Type
