Performance Glass Thruster Fin Set – 3K Carbon Base & Hex Core

Overview

Take your surfing to the next level with the Performance Glass Thruster Fin Set, designed for surfers seeking a responsive setup for technical maneuvers, speed, and control.

Featuring a 3K carbon-reinforced base, a lightweight Hex Core, and a flat-foil design, these fins are engineered to balance drive with moderate flex. The reinforced base supports power through turns, while the fin's flex characteristics are designed to help maintain speed and responsiveness.

Positioned as an upgrade from the M21 Polymer Flex Fins, the Performance Glass series offers an option for surfers looking for a more performance-oriented feel in their thruster setup.

Available in three sizes, the set includes options for different rider-weight ranges to help you select a suitable fit for your surfing style.
