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

Overview

More drive. Responsive flex. Performance-focused surfing.

The Performance Glass Thruster Fin Set is designed for surfers seeking a responsive fin setup for technical maneuvers, speed, and control. Featuring a 3K carbon base, lightweight Hex Core construction, and a flat-foil profile, these fins balance base stiffness with moderate flex for a performance-oriented feel.

Positioned as an upgrade from the M21 Polymer Flex Fins, the Performance Glass series offers a different combination of materials and flex characteristics for surfers looking to refine their turns and handling.

Available in three sizes, the set includes options for a range of rider weights. Choose the size that best matches your weight, board, and preferred surfing style.

Added Drive

The carbon-reinforced base increases stiffness in the area where force transfers between the board and fin, supporting drive when engaging the fins through turns.

Responsive Flex

The moderate-flex design aims to balance a firm base with controlled flex, creating a combination of speed retention and responsiveness.

Lightweight Core

The Hex Core is designed to reduce the amount of resin used and help keep the fin construction lightweight.

Speed-Focused Design

The flat-foil profile is intended to support speed and quick maneuvers, making this set an option for surfers who value responsive performance.
