A mask for underwater use includes a frame, a transparent part supported by the frame, and a gasket part mounted on the frame and configured to be positioned on the face of a user. The gasket part has a perimeter edge adapted to rest on the perimeter of the user's face, and the perimeter edge includes a discharge opening, which is located at the region configured to be arranged near the user's mouth and which is the seat of a valve non-return mechanism, which enables the expulsion of breathed gases simultaneously with any water present in the lower chamber through the opening.
