Power surfing needs the strength and performance of the SurfSilk Kaimana. Engineered with extreme stretch and flex, you're in for the ride of your life. Our exclusive SurfSilk performance fabric is what gives these surf trunks their superpower. Made from recycled water bottles, the outside is as tough as steel while the inside wears extremely soft and smooth against your skin. No rubbing, no rashing, just a supremely comfortable feel. And as for mobility, you won't find a boardshort with as much pop. 4-way stretch boosts the fabric with flex right where you need it. Progressive surfing requires progressive style. And you can rely on this 20" boardshort for men to deliver the best of both.
