Flyback design offers thin straps for greater freedom of motion and less strap irritation. 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, Lycra Xtra Life fiber resists deterioration and maintains its shape 5-10 times longer than spandex. That's why it's the new standard in swimwear fabric. Features: Durable fabric goes strong after 200 continuous exposure in the pool. Engineered to last 5-10 times longer than ordinary swimwear. Resists sagging, bagging and the effects of suntan lotion, skin oils, and chlorine. Bar tack reinforcements at stress points. Provides excellent support and freedom of motion. Fabric: 74% Nylon/26% Xtra Life LYCRA fiber.
