- 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.
- Construction – Thermotech (Natural White Composite) material is constructed from molded-resin with long-fiberglass matrix. This composite material fuses into a snappy and lightweight fin that retains the proper flex pattern for performance.
