How to measure
To get the most accurate measurements to find the right fit, follow these instructions.
- Place the tape measure snugly around your head at the widest point, about one inch above your eyebrows.
- Make sure the tape goes over the bump at the back of your head and that it is just above the top of your ears.
- Compare your measurements to our sizing chart.
- Place the helmet level on your head.
