The T1 Thermotech Twin +1 is Future's performance twin-fin designed for the type of small wave, in the pocket surfing that modern twin-fins are becoming known for. 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. The set is equipped with the option to ride with a small trailer fin for increased stability creating more of a thruster feel.
