Cressi matrix scuba mask offers total underwater visibility, featuring Cressi-subs patented angled-lens technology. The matrix scuba mask by Cressi-sub is designed to fit the faces of both men and women equally well. The Matrix is an excellent mask for snorkeling, scuba diving and skin diving. The Matrix mask lenses are now as close as possible to the eyes, taken to the maximum levels possible. The newly designed Matrix mask frame is very streamlined and ends up being completely invisible when the mask is worn. The top part of the Matrix mask has strong grip rubber material inserts, for a great look. The soft silicone skirt has a new profile and a broad seal ring for excellent waterproofing and comfort without precedent. The internal volume of the Cressi matrix dive mask is exceptionally low, lower than many well-known scuba-diving masks and the weight is also very moderate. Two pressure buckles integrated into the frame make strap adjustment quick and precise. This new design strap has a very broad purchase on the neck for magnificent comfort. Tear drop lens design for excellent downward vision. Lens angle increases underwater vision by 30%, low profile, crystal silicone. The highest grade silicone available for a soft comfortable seal. Easy to adjust strap buckle. The widest field of vision available today.
