Object of the invention is a mask comprising a frame, a transparent part supported by the frame, a seal part mounted on the frame and adapted to be placed on a user face and a snorkel. The seal part comprises a partition wall intended to rest on the user's nose, with the mask in the worn condition, such to form an upper chamber and a lower chamber, with the lower chamber receiving the nose and mouth of the user. The two chambers are in communication through a passage provided in the partition wall and through a one-way valve such that air can pass from the upper chamber to the lower chamber and not vice versa. The snorkel, comprising at least one first and one second channel that put the upper chamber and the lower chamber in communication with the external environment respectively, has a connection end between snorkel and mask. The connection end is fastened at an opening of the seal part such to put the first channel of the snorkel in communication with the upper chamber of the mask and has at least one side inlet for a corresponding exhaust tube that puts the lower chamber in communication with the second channel of the snorkel.
