Offering classic Speedo style, our Thinstrap Muscleback swimsuit is a great choice for lessons and training. Sleek in black with contrasting pink straps and Speedo logo, the muscleback style includes thin, supportive straps for total flexibility during their swim. Offering higher chlorine resistance than standard swimwear fabrics, the swimsuit provides excellent shape retention and fits like new for longer with CREORA® HighClo. In addition, nylon yarns in the EnduraFlex fabric are made from 100% pre-consumer waste, such as waste fabric from factories.
