Part of the arena Team Line collection inspired by our swim champions and designed for the major swimming federations, the arena team women's challenge back one-piece is perfect for intensive and competitive swimmers. It's made from an extremely chlorine-resistant swim fabric that protects skin from the sun, is quick to dry and is super durable. The open back in combination with the thin straps and high-cut leg provides maximum freedom of movement, an excellent feel of water and a flattering look. It comes in a solid colour with arena's name on the hip. Lined through the front.
