The sophisticated design of the King Crab goggles features uniquely shaped flat lenses that combine fashionable style with perfect vision underwater. The lenses are shatterproof and feature external anti-scratch treatment, UV protection, and internal anti-fog treatment. The King Crab goggles feature comfortable TPR gaskets which form a watertight seal on the eyes and fit most facial profiles. The silicone strap and micro-adjustable buckle system are interchangeable with all the other masks and goggles in the Cressi Swim Line.
