Billabong Tanlines Surf Shorts. The Billabong Tanlines Surf Shorts are a sporty, confidence-boosting alternative to traditional bikini bottoms, designed for women who want a little more coverage without sacrificing style. Made from a soft yet durable recycled rib fabric, they offer just the right amount of stretch and support for active days in the water. The high-rise fit sits at the waist and covers the belly button for a flattering, secure feel, while thoughtfully placed seams help the shorts stay in place through paddling, pop-ups, and wipeouts. Finished with cheeky bum coverage, a fixed pull-on design, and subtle embroidered logo branding, these surf shorts blend performance, comfort, and modern beach style. 91% Recycled Polyester 9% Spandex. Lining: 92% Recycled Polyester 8% Spandex. Hand wash. Imported.
