Make a statement in Hyper Boom logo prints. Paying homage to our legacy graphics, this sleek black Hyper Boom Jammer includes a side panel print of our evolutionary Hyper Boom graphic in stylish shades of blue. With integral support and enhanced comfort, the jammer includes a drawstring waist for a tailored fit. Made from our durable Endurance+ fabric, which is quick-drying and 100% chlorine resistant. One of the yarns in this fabric is made from 100% post-consumer waste, such as recycled plastic bottles.
