the Z3R0D one piece swimsuit is constructed from our high quality Invincible fabric, made in Italy, and is the perfect choice whether you're training in the pool or relaxing on the beach. The Invincible fabric is flexible, quick drying and as it uses only polyester, rather than elastane, it is resistant to chlorine and always stays in shape, ensuring a much longer product life. The fabric also offers an SPF 50+ sun protection rating.
