Zone3 Women's Strap Back Swimsuit Developed by Zone3, the Strap Back Swimsuit is made using innovative Xfinity Renew fabric, a premium Italian performance material engineered for long-term use. The fabric is 100% chlorine-proof, resistant to sunscreen and sunlight, and rated UPF50+, helping the swimsuit retain its shape, structure, and colour even with frequent swimming. This makes it a reliable choice for athletes training several times a week, indoors or outdoors. Comfort and confidence are built into every detail. A high-performance Italian inner lining provides supportive coverage across a wide range of body shapes, while low-profile flatlock seams minimise irritation during longer sessions. The open-back strap design and streamlined straps allow unrestricted shoulder and upper-body movement, making it ideal for swimmers who prefer a less restrictive feel than a race suit. Now updated, the refined fit across all UK sizes ensures consistent performance, comfort, and wearability, session after session.
