The invention provides a reflective and breathable raincoat used for a police officer. The reflective and breathable raincoat comprises a raincoat body, two sides of which are provided with long sleeves. The raincoat body is provided with a rain-proof cap. The rain-proof cap can be detachably connected with the raincoat body. One side, corresponding to a human face, of the rain-proof cap is provided with a transparent rain-shielding piece. The rain-shielding piece is detachably connected to the rain-proof cap. The raincoat body is of a double-layer structure. A separation strip is arranged between an inner layer and an outer layer. The outer layer is provided with breathable holes. The lower end part of the outer layer is provided with an air inlet. The breathable holes are externally provided with outwardly-protruding rain-shielding scales. The outer side surface of the outer layer is provided with reflective strips. The reflective and breathable raincoat used for the police officer has the following beneficial effects: the reflective and breathable raincoat is reasonable in design and compact in structure; the raincoat has a double-layer structure; the inner layer is separated from the outer layer by the separation strip; the raincoat is breathable; due to the fact that the breathable holes are arranged in the outside and the air inlet is arranged at the lower end part, air-flow circulation is formed between the inner layer and the outer layer; and the reflective and breathable raincoat is more comfortable to wear.
