How to Measure
Follow the instructions below and compare your measurements with the size chart
Head Size
Measure the head circumference just above your ears and eyebrows. The helmet should sit low, level on your head and it should not be tilted.
Tip! Use a soft measuring tape, to ensure that the product fits properly. Alternatively, use a piece of string and then measure it against a ruler
