No one should ride without a good helmet. It is not only required by low but also, it is common sense. Any modern helmet features three main layers of protection each of which performs its own function. The inner liner and padding provide comfort and noise insulation. Make sure that the helmet you choose sits snugly on your head. The mid-layer Styrofoam is designed to be partially crushed while absorbing most of the energy of the impact.
Arguably the most important layer, the hard outer shell created to disperse the energy of impact over the larger surface area, can be implemented in a variety of shapes, sizes, and designs with the use of different materials. Depending on your application and riding style, you’d better choose a suitable helmet that can protect you in case of an accident. Read a full article on the subject available at the link below:
