With Arai's helmet for example, 57cm-58cm needs to wear a helmet head size M. It is worth noting that every helmet manufacturer has different size setting standards, which ensures that they are judging their sizes according to the size table of helmet manufacturers, because manufacturers and manufacturers are likely to be different, which leads you to buy the wrong number. For example: usually wear No. M Arai, L Suomy may need to wear a big enough.
