Part of the Arena Team Line collection inspired by our swimming champions and designed for the largest swimming federations, the Arena Team Girls' Challenge Back One-piece is ideal for intensive and competitive swimmers. It is made from an extremely chlorine-resistant MaxLife Eco swim fabric that protects the skin from the sun, dries quickly and is extremely durable. At least 50% of the polyester is recycled, making it ideal for intensive training. 

The open back combined with thin straps and its medium-cut leg provide maximum freedom of movement, excellent water feel, and less resistance. It comes in a solid color with the Arena company name printed on it.
