How to choose a helmet that suits you?

If the helmet fits the head but does not hurt when clamped, then the helmet is suitable. Generally speaking, helmets, especially full helmets, the larger the contact area with the head, and the more suitable the helmet is for you, the safer it will be. The most ideal condition is that all parts of the full face helmet, except for the lenses, fit tightly to the head and face, which is the best. Of course, if it’s a little tight and it’s not particularly uncomfortable even if you wear it for a long time, then you don’t need to worry at all.
