Designed by legendary CI shaper Al Merrick The AM2 Alpha is a balanced thruster set featuring a slightly smaller centre fin for added manoeuvrability. A wider base offers increased drive through turns, making it ideal for high-performance surfing.

Thermotech fins have a consistent flex that creates drive and release through turns, unlike traditional composite fins. Thermotech fins come with the Futures Truss Base, making them lighter and stronger.
