Measuring: Measuring the circumference of the head is best accomplished measuring at a point approximately one inch above the eyebrows in front, and at the point in the back of the head that results in the largest possible measurement
It is strongly recommend to use a cloth tape (sewing measuring tape) or a string and then measure the string with a conventional measuring tape. Wesco Performance strongly recommends using the metric increments on the tape for the most accurate measurement. Best to take several measurements and then use the largest result.
