In the case you don't know exactly the size of your polo helmet, here is a small tutorial, so that you can learn how to take the measure of your head. This way, you can choose the perfect size for you, whether you buy it online or you go directly to the shop.
What you should do is take a measuring tape and place it just above your eyebrows and ears, forming a slight diagonal line around your head. Measure the circumference around your head 2.5cm above your eyebrows and just above your ears. (as shown in the picture).
