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 provide maximum freedom of movement, 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.

Extended Youth Sizing: If your measurements are close to or exceed the upper size range available in our youth sizes, we suggest that you also look at our smaller adult sizing (22–28) of this training style. These smaller sizes are designed and sized with the smaller swimmer silhouette in mind. To ensure a proper fitting suit please refer to the size charts for this style and take key body measurements.

Every component of the STANDARD 100 by OEKO-TEX® labelled fabric has been tested for harmful substances and the article therefore is harmless for human health. The test is conducted by our independent OEKO-TEX® partner institutes based on our extensive criteria catalog.
