You can’t beat the Modern Keel for a high performance twin. These things cut through water like a hot knife through butter but still hold tight when it’s time to go vertical!

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.
