New Flyback! Thin strap silhouette with reinforced overlap binding with excellent support and freedom of motion. 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.
