The Prince is a new version of the Cressi full face mask line, designed for frequent use while retaining the special features that set it apart from competitors. It maintains the design of its predecessors, the Duke and Baron, which allows for smooth, effortless breathing and completely prevents carbon dioxide from backflowing. The unique side channels direct exhaled air into separate ducts, preventing the buildup of carbon monoxide near the face. The Prince's airflow is significantly better than that of any other mask on the market. Tested in the laboratory of the Engineering Department at the Polytechnic University of Milan, the results exceeded expectations. This technical feature solves common issues seen with competing masks, making it especially safe in all situations. The mask has a facial skirt made of soft silicone, a more comfortable and durable material than PVC. The silicone is stretchable and adheres easily to the face without needing to tighten the head strap. The head strap, made of silicone, features an X-shape design to ensure a secure fit.
