Cal Twin

The Cal Twin is the twin fin that bridges vintage soul with modern performance—a board that feels magic under your feet. Originally inspired by a customer's treasured '80s twin, Doc refined the proven outline and vee bottom with contemporary dimensions for today's surfing. It paddles early, generates speed where twins typically stall, and responds crisply through hard turns.
