How to choose the right helmet size?
Correct size selection according to the size chart
Use a tailor’s measuring tape to measure the circumference of your head at forehead level, just above the ears. Compare the result with the size chart. If your head circumference is between two sizes, choose the larger size. When selecting a helmet, it is very important that it does not press too tightly on your head when first put on. Discomfort caused by a helmet that is too small becomes especially noticeable after 10–15 minutes of use. A slight feeling of tightness is acceptable — the helmet, like shoes, will adapt to the shape of your head after several hours of use. Remember that the helmet is the most important piece of equipment protecting your head. Choosing the correct size is essential for safety.
