The invention discloses unidirectional breathable cloth. The unidirectional breathable cloth comprises an inner layer, a base layer and an outer layer, wherein the inner layer is a breathable layer, aplurality of vent holes are formed in the base layer, a blocking layer is arranged on the base layer, valves corresponding to each breathable hole are arranged on the blocking layer and cover the vent holes, the areas of the valves are more than the areas of the breathable holes, the valves are rotatably connected with the blocking layer, the outer layer is arranged on the blocking layer, and a gap is formed between the outer layer and the valves. The unidirectional breathable cloth has the advantages that the inner layer can be manufactured from breathable cloth, so that the contact hand feel between the inner layer and a human body is improved; the blocking layer is covered by the base layer, the valves of the blocking layer serve as the valves of the vent holes and cover the vent holes, and the areas of the valves are more than the areas of the breathable holes, so that the valves can be unidirectionally opened to enable internal gas to flow out through the vent holes; and the valves cling to the vent holes so as to close the vent holes while meeting reverse airflow, so that the unidirectional breathable cloth in proper sense is realized.
