2. The main function of the buffer layer is to absorb external impact. If a helmet with a hard shell does not have a buffer layer, when it encounters an external force impact, the external force will directly act on the head through the hard shell, causing the head to be injured. Therefore, the thickness of the buffer layer and the quality of the material determine the buffer capacity of the helmet. The buffer layer is mainly made of foamed styrene material.
 3. The main function of the inner lining is to enhance the comfort of wearing, and it is generally made of soft flannel.
