DUKE is not Cressi's first full mask for snorkeling, as early as the 1950s Cressi marketed its MEDUSA mask with a double snorkel, which integrated eyes, nose and mouth in a single space.

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

The situation of the lateral breathing tube 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 channeling integrated in the tube, with a powerful "chimney" effect that prevents the accumulation of a percentage of this air in the breathing zone. The air circulation in Duke is clearly superior to that of any other mask on the similar market. We had the opportunity to test it in the laboratory of the Milan Polytechnic Department of Engineering, where the results exceeded our expectations.

The breathing system that we have designed and patented, because it does not use the old breathing system through a center tube system, does not require the need for forced breathing to travel a longer distance and open more than one valve. The double tube section means that one is connected to the breathing chamber and the other to the vision chamber. This advantage is enhanced by the fact that neither the breathing chamber nor the tube have valves to prevent the user from breathing.

This design, together with the deflector that directs a small incoming air stream into the vision area, guarantees the absence of exhaled air in the vision chamber, drastically reducing the tendency to fog 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 top valve system by means of a buoy that prevents the entry of water due to waves or complete introduction of the head under water.

DUKE's watertightness is ensured by three large safety valves, which only act when water enters the vision area (2) and the breathing area (1).

The transparent or black silicone facial depending on the version has been studied, following the Cressi tradition, for a fantastic adaptation to all types of physiognomies with only two sizes: S / M and M / L.



Colors: Transparent-silver, Transparent-yellow, Transparent-blue, Transparent-pink, Transparent-black, Transparent-red, Transparent-lime, Dark-blue, Dark-black, Dark-red
Sizes: S / M, M / L

IMPORTANT NOTICE: Mask for observation of the bottom from the surface. It is not possible to compensate the ears by means of the Valsalva maneuver (pinching the nose) or tackling by exhaling through the nose, so it should not be used in a dive below 1.5 m depth.
