A breathable mask includes a main frame, a transparent lens portion, a water-sealing skirt and a breathing tube. The main frame includes a lens frame, a mouth frame and a nose frame interposed therebetween. The water-sealing skirt is integrally formed by an eye skirt, a nose skirt and a mouth skirt, and a skirt frame is arranged in front of the eye skirt. The transparent lens portion and the skirt frame are embedded in the lens frame in a water-sealing manner, and the nose skirt protrudes outward from the nose frame. The transparent lens portion does not project outward from an outer edge of the lens frame at all.
