ABSTRACT:
A helmet for use in riding vehicles such as motorcycles, motorbikes, etc. comprises a cap like body made of hard material, a bumping body applied on an inner surface of the cap like body, a number of streamline recesses formed in the bumping body and extending from a forehead portion to a backhead or side portion of the cap like body. When a user wears the helmet, the air stream flows through the recesses from the front openings to the rear openings of the recesses and thus the temperature and humidity inside the helmet are decreased.
