Helmet fitment is essential to the operation of a helmet during an impact. For the helmet to perform correctly during an impact, it must remain on the head.
Measuring the head is just a starting point for the entire sizing procedure.
A small metal tape measure or a cloth tape may be used to make your first measurement. You may also use a cord, which can subsequently be set against a measuring tape.
Take several measurements. The greatest measurement is the one you need to use.
