Cressi Duke Full Face Mask

The Cressi Duke Full Face Mask is the snorkeling visor that allows you to explore the underwater world from the surface. Duke offers a natural breathing experience due to the absence of any valve (patent pending), and a fog-free vision obtained by the lateral deflector mechanism (patent pending).

Cressi Duke Full Face Mask

Cressi Duke Full Face Mask is a full-face mask (FFM) and it is designed to give the user the opportunity to breathe easily.

These three features put Duke in a class of its own:

  • The advantage of lateral tube position.
  • An excellent Anti-fogging effect.
  • A minimal build-up of residual CO2.

The reason why Cressi has chosen to position the tube laterally is that it is the shortest route possible for airflow with minimal effort.

Its left-side tube is divided into two before entering the two separate chambers.

One is connected to the breathing chamber and the other is connected to the vision chamber. This advantage is enhanced by the fact that neither the breathing chamber nor the tube have any valves to impede the user’s breath.

What’s more, the extraction chamber has an enlarged volume in order to allow for optimal CO2 extraction. Something interesting to note is, this airflow system in Duke produces far less co2 build-up than a safety gas mask.

The second independent tube. It’s connected to the vision chamber and extracts moisture and warm air that builds up in this chamber, completely separate from the breathing chamber.

Duke has a deflector, which is also under patent, which maximizes the extraction of warm air produced by the face when the mask is worn, and it is designed to work like a chimney effect forcing air circulation away from the lens.

Finally, Duke has large outlet valves at its base, to drain the mask quickly & easily if it fills up with water. One large outlet valve below the mouth which has nothing to do with the breathing system.
