This streamlined boys’ Speedo Hyper Boom Logo Placement Jammer features a cool spray-paint effect Speedo Boom graphic in bright blue. Lined at the front for comfort and modesty, it includes an internal drawstring to allow young swimmers to adjust the fit. Providing higher chlorine resistance than standard swimwear fabrics, the jammer offers excellent shape retention and fits like new for longer with CREORA® HighClo™. If you’re looking for great eco-credentials, it’s got those, too: Speedo-exclusive Eco EnduraFlex fabric is made from 100% recycled pre-consumer waste, such as fabric waste from factories.
