Description
Cressi EVO Big Eyes Crystal Mask
It will be difficult to overcome the new Evo Cressi mask, a limit design exercise that improves the optimal visibility in all directions of MATRIX and reduces weight and intern volume of parameters of much little masks (160 gr and 115 cm3).
It’s identical regarding the design to the EVO BIG EYES version, the CRYSTAL uses exclusively the new silicone Crystal of Cressi that gives to the sector advantages long-awaited:
- Absolute transparence that provides a great interior lightning, fabulous aesthetics both as product and on the diver’s face (especially in underwater photography).
- Tendency to yellowish color with the pass of time 90% less than other kinds of silicone due to its exclusive chemical composition.
- It has no silicon chloride, a component that causes the traditional and annoying glass greasing after the mask’s assembly that must be eliminated to achieve a good use of the mask. The Crystal silicone doesn’t grease the screen and, so, it has no incidence on the tendency to the mask’s fogging.
2nd silicone mixture used for the internal part of the skirt (shore 60) and the subjection strap in an attractive silver color.
Evo skirt with two silicone of different density to obtain an especially dynamic perfect stability over the face with a great comfort and adaptation capacity. The internal part of rigid silicone gives solidity and stability to the mask. The exterior profiles of a very, very soft reinforced silicone increasing thicknesses in key areas, especially the sides (critical area using very flexible compositions) and the contact area with the frame, provide an unparalleled comfort.
The exterior part of the skirt in contact with the face and the part that recovers the nose have decreasing thickness that improves adaptation and maintains the comfort during long usage hours.
Completely pivoting tilting belts in all directions joined to the frame through flexible and unbreakable elastomer. The strap’s tension acts directly over the frame, maintaining the mask’s stability and approaching to the maximum the glass to the eyes.
Exceptionally reduced frame structure that allows a great approach to the glasses without contact problems with the frame. So, the intern volume is reduced to the minimum and all frame vision is eliminated from the inside. 15º inclined and extended glasses over the cheeks (“Big Eyes” system) increase the inferior visibility more than 30% regarding the one of a traditional mask, while the superior and side visibility are increased to the limit that allows the frame’s thickness: total vision -3% in superior visibility and total vision -5% in side visibility.
Particularly studied structural rigidity of the central bridge to avoid losing the plane of the glasses due to an excess of tension of the strap that could cause optical distortions.
Graduated glasses for myopia from -1 to -6 dioptres (half by half).
