HOW TO FIND THE RIGHT SIZE
- Ensure the tape measure is straight and not twisted to obtain an accurate measurement.
- If a tape measure isn’t available, use a piece of string to encircle your head, then measure the length of the string with a ruler.
- If uncertain about the size or in between sizes, opt for the larger size to ensure a comfortable fit.
