The Futures F8 Thermotech Quad fin set. One of the most popular templates available as a quad setup. The F8 fin is a great template for large sized riders looking for a fin that's a little looser, or for medium sized riders looking for a setup with a little more drive. Thermotech is Futures new composite material, with the Truss Base making them lighter, and designed to break under impact reducing the risk of injury to yourself and your board. The fin’s solid base transfers power, while the tip still has enough flex and resilience allowing it to bend and load up, overall a pretty close feel to a glassed-on fin.
