A cute suit that’s built to last with a 300+ hours performance rating the TYR Castaway Diamonfit Girl's Swimsuit has a modest leg cut and open back with flexible spaghetti straps for a 360 degree range of motion, whether she’s cutting her way through training laps, or tackling the challenges of wakeboarding this summer. A formidable contender for the serious swimmer this performance swimsuit has a high denier poly fiber and innovative circular knit construction to provide support, and the strength and colorfastness of polyester blended with spandex for stretchy, easy moving, support. If you’re comparing suits, the Durafast Lite® fabric has twice as much spandex, for a stretchy fabric that feels a bit lighter, not quite as robust around the torso. If you’re looking for a suit designed for fun in and around the water, with less of a competitive spin to it, the Castaway Diamondfit has similar styling to the women’s version for a suit with summer style and the UPF 50+ protection you want for her when she’s out at the beach. A casually styled suit for the athlete who wants beach and pool wear that is just as comfortable sitting on lounge chair or building a sand castle as it is jumping off the diving board or dock.
