Description:

It will be hard to beat Cressi's new EVO, an exercise in design to the limit that improves the already optimal all-around visibility of the MATRIX and reduces weight to 160 g and internal volume to 115 cm3, parameters typical of much smaller masks.

Identical in design to the EVO BIG EYES version, the CRYSTAL uses a new exclusive Cressi Crystal silicone that brings long-awaited advantages to the industry:

Absolute transparency that provides great internal luminosity, fabulous aesthetics both as a product and once placed on the diver's face (to be valued especially in the case of underwater photography models).

Reduced tendency to yellowing over time, 90% less than other types of silicone due to its unique chemical composition.

Silicone free of silicon chloride, a component that causes the traditional and cumbersome greasing of the lenses after the assembly of the mask and that must be eliminated to achieve a correct use of the mask. Crystal silicone does not grease the mask shield and therefore has no effect on the tendency of the mask to fog up.

The 2nd silicone mixture used for the inner lip of the skirt (shore 60) and the fastening strap differs from the standard model with an attractive silver color. 

The facial mask combines two types of silicone with unprecedented technical improvements.  The inner lip of rigid silicone gives solidity and stability to the mask. The outer profiles of a very, very soft silicone reinforced by increasing thickness in key areas, especially the sides (a critical area when using very flexible compositions) and in the area of contact with the frame, provide unprecedented comfort.

The outer lip of the facepiece in contact with the face and the area covering the nose have a decreasing thickness that improves adaptation and maintains comfort during long hours of use.

Also noteworthy are the buckles, fully pivoting in all directions and attached to the frame by means of a flexible and unbreakable elastomer. The tension of the strap acts directly on the frame, maintaining the stability of the mask and bringing the glass as close as possible to the eyes.

The exceptionally small frame structure allows a close approach to the lenses without any contact problems with the frame. The internal volume is therefore reduced to the absolute minimum and any view of the frame from the inside is eliminated. The 15° inclined lenses extended above the cheekbones ("Big Eyes" system) increase lower visibility by more than 30% compared to that of a traditional mask, while upper and side visibility are increased to the limit allowed by the thickness of the frame: total vision - 3% in upper visibility and total vision -5% in side visibility.

The structural rigidity of the central bridge has been particularly studied to avoid the loss of the lens plane due to an excessive tension of the strap that could cause optical distortions. 

Possibility of graduated lenses for myopia from -1 to -6 diopters from medium to medium.

Available in: Yellow, Blue-black, White-pink, Clear-black, White-blue.
