The Arena Womens O Back Swimsuit Solid is engineered for active women who spend serious time in the water. Crafted from 80% polyamide and 20% elastane (Waterfeel Eco Fabric), the suit delivers a second-skin fit, outstanding 4-way stretch and all-day comfort during intensive training sessions. The signature O-back design features a high neckline, a large back cutout and wide supportive straps, combining a feminine aesthetic with unrestricted freedom of movement in every stroke. Thanks to its chlorine- and saltwater-resistant fabric with built-in UPF 50+ UV protection, this one-piece performs equally well in indoor pools and open-air environments.
