The Skylight swim mask has an innovative frame design, unique to Cressi. This mask uses mono-lens technology, ensuring maximum comfort without the irritation of a regular goggle. The innovative shape of the frame delivers a maximized peripheral view. The lenses are manufactured with an internal anti–fog treatment, are scratch-resistant, shatterproof, and 100% anti-UV. The silicone strap provides a secure and stable fit on the face for long periods in the water. Our patented easy-adjustable buckle system has made it among the very best, for many years.
