Z1R Helmet Size Chart:
HOW TO DETERMINE YOUR CORRECT HELMET SIZE.
1. MEASURE YOUR HEAD. Determine the circumference of the widest part of your
head by using a flexible tape measure. Generally, the widest part of a person's
head is the area 2.5 cm (1") above the eyes and ears. However, we suggest
measuring at a few points both above and below that line to determine the
greatest measurement before referring to our size tables. We also suggest
testing the fit of a helmet one size smaller and one size larger than what the
chart recommends. No helmet can provide protection if it's too uncomfortable to
wear.
