A breathable mask includes a body having a main frame, a lens, and a waterproof sealing skirt. The waterproof sealing skirt has a partition dividing the interior of the body into an upper chamber that shields the eyes and a lower chamber that shields the nose, and arranges independent air intake passages and exhaust passages to separate the fresh air inhaled and the dirty air exhaled. Alternatively, a nasal connecting portion having a purge valve can be provided in fluid communication with the lower chamber. It is also possible to provide a three-way connector having a nasal connecting portion, a mouth portion, and a drain portion in fluid communication with one another, wherein the nasal connecting portion is in fluid communication with the lower chamber. The mouth connecting portion is adapted to be contained in the user's mouth when the user well wears the breathable mask.
