Performance Glass (PG) fins are machine cut from layers of solid fibreglass. PG fins have very fast memory recall which translates into speed. These fins are stiff, providing immediate response and acceleration as the surfer powers up and drives through a turn, while maintaining flex integrity under immense force and in extreme conditions and situations.
PG fins are widely used by pro-level surfers.
