Worn and loved by Speedo athletes, the Hiro Cap is the latest addition to the Fastskin range. Made for racing, its tight-fitting moulded design is engineered to reduce drag and includes a full gloss interior for improved grip as you power through the water. Created from thinner material for a dynamic, wrinkle-free fit, its moulded design enables it to hold its shape for a streamlined silhouette. World Aquatics Approved.
