This swimsuit is designed with all levels of swimmer in mind. Lasting up to seven times longer than regular Spandex, the exceptionally comfortable material fits close to the body, retains its shape thanks to its two-way stretch and is highly resistant to chlorine so you can focus on your swim no matter how many times you train in it. Offering an anatomical fit, medium thigh length, internal lined bust support and a modest open back for unrestricted range of movement during every stroke, this suit is finished with flatlock stitching to ensure maximum strength and comfort during exercise.
