Designed for swimming, paddling and training, our Sunamee bikini bottoms fit straight across the hips and have a full-coverage seat. Made from a soft, durable and stretchy body fabric (solids: 83% recycled nylon/17% spandex jersey; prints: 83% recycled polyester/17% spandex jersey), they feature hidden seams and hidden elastic at the leg and waist openings for a comfortable, flattering fit that stays in place without pinching. A swim-specific 88% nylon/12% spandex lining adds modesty and lies comfortably against the skin. Fair Trade Certified sewn.
