THE MATRIX DIVE MASK Technology has a new shape! Following the revolutionary principles introduced by Big Eyes, the Cressi-Sub Matrix dive mask establishes new records. The Cressi patented raked mask lenses and their special INVERTED DROP shape has been developed even further. 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 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. The Matrix is an excellent mask for snorkeling, scuba diving and skin diving.
