Legendary bodyboarding pioneer Pat Caldwell was known for many things: inventing the el rollo, charging fierce waves with a wounded-duck style, and of course his blue and white two-tone signature model from Wave Rebel. The Pat Caldwell model featured a Flextreme bottom skin, offering a thicker, high strength bottom for speed, performance, and durability. Wave Rebel bonded the skins with a trademark "Hydra-Fusion" process, which reportedly resulted in optimum flexibility and longevity. Photo: Bryan Simmons.
