Speedo Digi Suntop Boys Bring a burst of neon colour with our latest Skull Rashtop. The long-sleeve, pull-on style offers protection from the elements, while the UPF50+ fabric provides sun protection both in and out of the water. Our Endurance + fabric offers 100 % chlorine resistance. Yarns in the fabric are made from 100% recycled waste fabric, so it's better for the environment too.
