These aren't flimsy leggings masquerading as surf material. Thanks to 2mm of reversible neoprene, the Kassia Surf 2mm Reversible Surf Leggings feature a well-considered design that's been engineered to provide you with bonus warmth for bumper season expeditions and chilly mornings on dawn patrol. Snag 'em in your size and dial in the fit using the drawstring waist that keeps water out and warmth in.
