Matrix:  

Following the revolutionary principles introduced by Big Eyes, the Matrix establishes new records. The Cressi patented raked 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 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.
Excellent mask for snorkelling, scuba diving and skin diving.

Gamma: 

Profiled guard: this drastically reduces water intake and splashing from the top without blocking breathing.
Adjustable attachment: system of quick-attachment to the mask strap, which runs along the snorkel bore for perfect positioning.
New drainage well: this draws all the remaining water to the bottom end of the tube, preventing all blockage to breathing.
Internal elliptical valve: the elliptical valve optimises water drainage, making it quick and easy to purge the snorkel.
