Measurement
 Proper
helmet fit is a vital component to the performance of a helmet
during an impact. In order for the helmet to perform properly
during an impact, it must stay securely on the head.
Measuring the head is a starting point for the entire sizing
procedure. Due to varying shapes, heads that are apparently the
same size when measured by a tape may not necessarily fit the
same size helmet.
A small metal tape measure, or a cloth tape may be used to
make your initial measurement. Alternatively, a string can be
used which can then be laid against a measuring tape.
The circumference of the head should be measured at a point
approximately one inch above the eyebrows in front, and at a
point in the back of the head that results in the largest
possible measurement. Take several measurements, to make sure
you have the largest one.
