Classic sports styling, straight from the Speedo archives. Throwing it back to our Bondi roots, weve raided the Speedo design archives for the new navy Hyper Boom Spliced Jammer, which features a revival of our iconic go-faster boom logo stripe. Sleek and stylish with a rubberised liner and integral support for enhanced comfort, the jammer includes a drawstring waist for a tailored fit. Designed to be durable and better for the environment, its made from our ECO Endurance fabric, which is 100% chlorine resistant, quick-drying and made from 50% recycled materials.
