Abstract: The present invention relates to a breathable mask having a body and a snorkel being in fluid communication with an interior of the body. The interior of the body is provided to divide the mask into an eye pocket and an orinasal pocket. The total inner volume of the eye pocket and the orinasal pocket is not more than 500 ml. In the circumstance a snorkeler wears the snorkeling mask, the total of the inner volume remaining in the eye pocket and the inner volume remaining in the orinasal pocket does not exceed 400 ml. By reducing the inner volume of the mask, the snorkeler can completely or nearly breath out all the dirty air under his/her normal tidal volume of every breath, forming a temporary vacuum in the mask, and allowing the external fresh air to be ready to enter the mask actively after the snorkeler takes a next inhalation, thereby the snorkeler can have an easy and safe breath.
