Big Eyes Evolution Adult Size Scuba Mask The mask rests on the face with unprecedented comfort and does not leave any marks on the skin, even after extended use. The raked lenses, with their inverted drop shape (Cressi patent), are quite small and are brought as close to the pupils as possible, so that the already extraordinary visibility of the Matrix is increased by 25%. The thickness of the headband has been reduced to such an extent as to make it practically invisible when the mask is being worn. Supernova Dry Adult Size Snorkel All the great performance features of a snorkel are incorporated into the Dry. Its low profile design eliminates water entry while submerged, while achieving outstanding breathing performance while on the surface. Smooth bore tube with flex section for scuba use. Large, easy to clear, exhaust valve.
