Super Pro Back Print! Features wide straps for superior support and comfort. Designed with Xtra Life Lycra® Fiber for a long-lasting fit. Swimsuits have to contend with some pretty harsh stuff; chlorine, perspiration, greasy oils found in sunblock, and stretching from constant use. Designed with those challenges in mind, Xtra Life Lycra® fiber resists deterioration and maintains its shape 5-10 times longer than spandex. That's why it's the new standard in swimwear fabric.
