MEASURING YOUR HEAD before purchase: A small metal tape measure, or a cloth tape may be used to take your measurement. If possible, have a helper do the measuring in order to get a more accurate measurement. The circumference of the head should be measured at a point approximately one inch above the eyebrows, or at whatever point gives the largest possible measurement. Then check the SIZE CHART above for a correct custom fit. Helpful Sizing Tips To get your size measurement please measure the circumference of the hand all the way around the palm and four knuckles in as straight of a line as possible. Do not include the thumb in the measurement. Then compare your measurement to the chart to find out what size you need.
