The suitability of helmet can be worn on any head type. However, attention should be paid to the ventilation and size of the helmet. When riding with helmets, you should not feel that the helmets tighten your neck and wrap your head tightly, causing poor breathing. At the same time, the size of the helmet should try to choose the appropriate safety helmet that will not move and will not wear the protective sleeve at the bottom of the helmet when it is frequently removed and put on.

FRP is better than ABS. It is lighter and stronger, but it is also more difficult to make. The output is lower, so it is much more expensive than ABS. The inner side of the helmet must be equipped with an anti impact pad. The surface pad material matching the head is thin mesh lining, which should have the effect of absorbing sweat and oil from the head. In addition, a ventilation slot with a depth of more than 10MM shall be provided on the liner to allow air circulation in the helmet.
