How to Measure

Follow the instructions below and compare your measurements with the size chart

Circumference of the Head

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.

Neck Circumference Measurement

Measure the neck circumference, including the zipper (if present).

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
