Pro-tec Classic and Old School Helmet Size Chart

We recommend measuring your head to determine helmet size. 

Instructions below for the Pro-tec Classic Skate and Pro-tec Old School Certified Helmets.

To ensure that your helmet fits perfectly, we recommend measuring the circumference of your head using a measuring tape. For accurate measurements, wrap the measuring tape just above your eyebrows and around your head. Compare your cm measurement to the chart to find your ideal helmet size.
