The Middle Finger or TMF is designed to be ridden as a 5th fin with a quad set, giving more hold and stability.
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.
