Duke

Cressi’s 2020 Duke full face mask is designed with safety in mind. With a 30% larger viewing area, snorkelers can see all the underwater world has to offer without feeling claustrophobic. The dry snorkel keeps water out, while a specialized deflector maximizes air circulation and eliminates fogging. The valve’s design gives the user effortless and natural breathing, with a wide breathing area around the nose and mouth. Water draining valves safely remove any water that may enter the mask. This mask is designed for surface use only and should not be used at depth.
The face skirt is made of soft hypoallergenic silicone that ensures comfort and a perfect seal. The two x-cross straps are easy to adjust for a perfect fit. The frame and lens are made of polycarbonate.
The Duke is made in two sizes to ensure proper fitting. It's sold with a nice nylon package with zipper for storage.
