Mask Duke

The Duke project has required in-depth design and air circulation studies, both inlet and outlet, in order to solve the common problems in these masks in competing models and make the Cressi face mask especially safe in any situation.

The location of the side snorkel and the fact that the closing or opening of valves is not required for its operation, guarantees a large supply flow, unthinkable in other similar models, especially in case of fatigue or stress. The evacuation of stale air is also produced by a second channel integrated into the tube, with a powerful "chimney" effect that prevents the accumulation of a percentage of this air in the breathing area. The air circulation in Duke is clearly superior to that of any other similar mask on the market. We had the opportunity to test it in the laboratory of the Engineering Department of the Milan Polytechnic, where the results exceeded our expectations.

This design, together with the deflector that directs a small stream of incoming air inside the viewing area, guarantees the absence of exhaled air in the viewing chamber, reducing the tendency to fogging drastically while maximizing the extraction of hot air. produced by the face when the mask is worn, and is designed to function as a chimney effect that forces air circulation away from the lens.

The design of the viewing area allows 30% more angle than most similar masks without distortion.

The tube has a dry upper valve system using a buoy that prevents water entry due to waves or complete introduction of the head under water.
