Material Performance Glass Solid fibreglass fins have for decades been the go-to construction for many of the worlds best surfers. 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. PG fins have very fast memory recall which translates into speed. These fins generally sit at the higher end of the stiffness scale, providing immediate response and acceleration as the surfer powers up and drives through a turn.
