High-end performance meets standout style. Dive into the water in the extremely durable, chlorine-resistant, and eye-catching arena Monogram Challenge Back Swimsuit for women, part of the arena Performance line. Designed for both competitive and regular swimmers who train frequently, this sleek suit is made with arena's MaxLife fabric—highly chlorine-resistant, fast-drying, and built to last. It also provides UPF 50+ UV protection and is made with at least 50% recycled polyester from PET bottles. The open back, thin straps, and high-cut leg offer unrestricted movement, reduced drag, and a smooth feel in the water. A comfortable front lining adds confident coverage, while the OEKO-TEX STANDARD 100 certified fabric ensures it's been tested for harmful substances and is safe for long-term wear.
