Make a statement in HyperBoom logo prints. Paying homage to Speedo's legacy graphics, this sporty black HyperBoom Muscleback swimsuit features a graduated print showcasing their evolutionary HyperBoom graphic in striking shades of blue. The muscleback design and medium cut leg offer flexibility and freedom of movement, so you can swim in comfort. Front lined for comfort and modesty, it's made from the durable Endurance+ fabric, which is quick-drying and 100% chlorine resistant. One of the yarns in the Endurance+ fabric is made from 100% post-consumer waste, such as recycled plastic bottles.
