  • Overview

    • Matt 'Mayhem' Biolos's specialty quad fin set.
    • High area quad keel set adds bite and control to hybrid boards with wide tails, without sacrificing pivoting capabilities.

    Board Types

    • Designed to fit the FCS II Fin System.
    • Recommended for all board types including modern fish and hybrid models with moderate-to-low rocker.
  • Performance Glass

    Performance Glass (PG) fins are machine cut from layers of solid fiberglass. These fins are stiff, and are widely used by pro level surfers because the integrity of the flex is maintained under immense force, and in the most extreme of conditions and situations.
