A breathable mask is provided, which includes a body and a breathing tube in fluid communication with an interior thereof. The body includes a main frame, a lens, a waterproof skirt, a multi-channel connector, and intake and exhaust passages. The waterproof skirt has a partition dividing the interior of the body into upper and lower chambers, thereby accommodating the user's eyes and nose in the upper and lower chambers, respectively. The multi-channel connector has an upper end in fluid communication with the lower chamber. The intake passage is formed between the lower end portion of the breathing tube and the lower chamber. The exhaust passage is arranged upward along a periphery of the body to allow dirty air exhaled from the user to unidirectionally flow outward through the exhaust passage. The exhaust passage includes an exhaust tube with a bottom portion coupled to and communicating with the multi-channel connector.
