Performance Glass Thruster Surfboard Fin Set – 3K Carbon Base & Hex Core
Overview
Take your surfing to the next level with the Performance Glass (PG) Thruster Fin Set. Designed for surfers looking to progress their technical maneuvers, these fins offer a combination of base stiffness, controlled flex, and responsive handling.
A 3K carbon base adds stiffness where drive matters, while the Hex Core construction is designed to reduce weight and maintain a moderate flex response. The flat foil profile supports speed and quick maneuvering, making this set a performance-oriented upgrade from the M21 Polymer Flex Fins.
Available in Small, Medium, and Large sizes, the PG Thruster range helps you select a fin size suited to your body weight and riding style.
Key Features & Benefits

-
Flat Foil Profile: Designed to support speed and quick, technical maneuvers.
-
Performance Glass Construction: A performance-oriented fin design for surfers seeking more responsiveness than a polymer-flex setup.

Thruster Configuration: Designed for compatible three-fin surfboard setups.
-
Three Size Options: Choose Small, Medium, or Large based on the supplier's rider-weight recommendations.
Why These Fins Stand Out
The Performance Glass Thruster set combines a reinforced base with a lightweight core and a flat foil profile. This design aims to provide a balance of drive, speed, and responsiveness for surfers working on sharper turns and more technical maneuvers.
Compared with the M21 Polymer Flex Fins, the PG set is positioned as a performance step up for riders who want a stiffer base and more responsive feel.
Choose Your Size
| Size | Suggested Rider Weight |
|---|---|
| PG-S – Small | 120–150 lb |
| PG-M – Medium | 145–175 lb |
| PG-L – Large | 180–220 lb |
The weight ranges overlap because fin choice also depends on board design, wave conditions, preferred flex, and surfing style. Use the listed ranges as a starting point rather than a strict rule.
