Engineered in collaboration with the world’s top athletes, the Fastskin Pure Focus Mirror goggle delivers a 5% reduction in drag versus the Fastskin Hyper Elite, making it speedo's fastest and most advanced racing goggle ever. Innovative design features combined with speedo's pioneering IQfit technology ensure it delivers the ultimate synergy of speed, performance and style. Fully approved by FINA. IQFitSpeedo's first 3D eyewear seal was developed by Speedo Aqualab based on the research results of head scans from around the world. The exclusive seal adapts to the shape of the eyes without leaving unpleasant pressure points. At the same time, it ensures maximum tightness and accurate fit when starting and turning. Speedo's patented strap has a locking mechanism that ensures a precise fit when swimming. The 3D eyeglass seal does not have to fit as tightly as other models and is therefore softer on the skin. So you can fully concentrate on swimming.
