Make a statement in Boom logo prints. Celebrating the Speedo brand, our sporty Hyperboom Muscleback swimsuit showcases our iconic Boom logo in a purple graffiti-textured design. The muscleback design and medium cut leg offer flexibility and freedom of movement, so you can swim in comfort. The suit is front lined for modesty and comfort. Made from our durable ECO Endurance+ fabric, it's quick-drying and 100% chlorine resistant. Plus, one of the yarns in the ECO Endurance+ fabric is made from 100% post-consumer waste, such as recycled plastic bottles.
