The sophisticated design of the king crab goggles feature uniquely shaped flat lenses which 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.
