A cyclist helmet comprises a molded helmet body defining a recessed interior for receiving therein the head of the cyclist and a tail portion through which an air passage is formed with a first opening on the top surface of the helmet and a second opening located on the underside of the tail portion to allow air to flow therethrough and thus creating a negative pressure zone under the tail portion which provides a suction to exhaust the air inside the helmet interior. A fastening strip is provided to secure the helmet on the head of the cyclist.
