The Matrix mask establishes new records. The Cressi matrix patented lenses and their special inverted drop shape has been developed even further. The lenses are now as close as possible to the eyes, taken to the maximum levels possible. The newly designed frame is very streamlined and ends up being completely invisible when the mask is worn. The top part of the 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 mask is exceptionally low, lower than many well-known free diving and scuba-diving masks and the weight is also very moderate. Two pressure buckles integrated into the frame make the strap adjustment quick and precise.Excellent mask for snorkeling and skin diving.To get the best fitting mask, we offer a 14 day trial on all masks, if your mask doesn't fit or if it leaks return it for another.
