The innovative construction of the K180 swim goggle combines three different materials resulting in the most comfortable and stable swim goggle ever. The best optic technopolymers have been used for UV protection and anti-fog lenses. Ultra-soft TPR (Thermo Plastic Rubber) guarantees perfect stability in the eye socket and a comfortable, water tight fit. Curved lenses, designed according to Aqua Sphere's 180° Seal technology, give a wider field of vision. Additionally, the streamlined shape reduces vortices and enhances hydrodynamics. K180 is very easy to wear thanks to three different sizes of the nose bridge and the easy to adjust head buckles. K180+ has a micro-gasket for maximum performance
