Sharing the design scheme of the new D-Series D420 regulator, the new D-Mask is a sleek, premium mask well-suited for all types of diving. The D-Mask benefits from SCUBAPRO's second-generation Trufit technology. This design approach features a mask skirt with thicker, firmer silicone near the mask frame to provide support and rigidity, and thinner silicone contouring the face for comfort and to ensure a watertight seal. The mask features true-color UV protective lenses that deliver the best balance of surface protection and underwater clarity. It also features an interchangeable lens system for optional optical lenses.
