If we want to know if a helmet is the right size, we need to know the size and shape of our own head.

The head shape of foreigners is very different from ours, so we need to pay attention to the choice of helmet: the head shape of Chinese people is relatively flat and round, while the head shape of foreigners tends to be flat and pointed. We said that helmets are to be worn on the head, so in terms of design, the structure needs to be adapted to different groups of people, and different helmets are designed for different groups of people. Therefore, when choosing a helmet, we need to know our head shape.

The size of the head circumference, just like when we buy clothes, what size is suitable. The most direct way to get the head circumference size is to measure with a soft tape to directly get our head circumference size, and then buy a helmet according to this measurement value, do not make the mistake of buying an inappropriate size helmet.

Helmets are available in small, medium, and large sizes. You may only be able to buy a relatively suitable size, and then use the size adjuster rotary button to adjust to the most suitable size. After wearing the helmet, turn the helmet from one side to the other, from the front to the back, and see if it is comfortable to wear. If it is too loose or too tight, you need to continue to adjust or replace it.
