Performance Glass

Performance Glass (PG) fins are machine-cut from layers of solid fibreglass. 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.

New Sizing for Specialty Fins
