To determine helmet size,
carefully measure your head with a cloth tape measure. For
greatest accuracy, someone else other than yourself should
take measurements, and the tape measure should be held
snugly around your head.
Place the measuring tape COMPLETELY
around the WIDEST portion of your head, approximately 1"
above the eyebrows and just above the ears and at the point
on the back of your head that will give you the largest
reading. It is best to take several measurements and to take
the largest to determine head size.
Find your head size in
the chart below and then order proper helmet size.
If your head size falls between two head sizes listed, order
the smaller helmet size as the helmet must fit snugly.
