[0002] Motorcycle helmets are head protection devices for motorcycle riders. The main purpose of the helmet is to protect the rider's head when it is hit, prevent or reduce injuries, and even save the rider's life. Generally speaking, the helmet can be worn on any head shape, but attention should be paid to the breathability and size of the helmet. When riding a motorcycle with a helmet, you should not feel that the helmet is tight around your neck and your head, causing difficulty in breathing. At the same time, the size of the helmet should be selected as a suitable safety helmet that will not move when you shake your head and will not wear out the bottom edge of the helmet too much when you take it off and put it on frequently.
