The galileo goggles have marked a historical turning point in the swimming goggles sector. In actual fact, their fl at lenses are mounted on a rigid frame, just like a diving masks, thus guaranteeing perfect vision with no distortion. The shape of the lenses, which are perfectly fl at and have no side curving, also prevents annoying distortion at the sides of the lenses. The watertight seal is extraordinary and comfort is excellent. The strap has a quick adjustment system (cressi patented), similar to that used on the prestigious cressi-sub masks, which allows quick and easy adjustment. The shatterproof lenses have external anti-scratch treatment, uv protection and internal anti-fog treatment
