The BT fin is designed for agile performance in all conditions. The broad base offers exceptional drive and control off the bottom, combined with a sweeping tip profile for release of the top.
The construction features a carbon/fiberglass exterior molded with a laminated infusion process onto a honeycomb core structure. This makes the fin extremely lightweight while maintaining strength and stiffness. The Simmer Style composite fins are one of the lightest wave fins on the market; they weigh half the weight compared to traditional G10 fin.
