Start by wrapping a measuring tape around your head about a
half-inch above your eyebrows.
Then, you need to pull the tape comfortably tight in order to
achieve the best results. Measure two to three times
trying to get the same result every time.
If you get different measurements take the largest size.
If you are between sizes, choose the next largest size.
Now take a look at the Size Chart to find out the right size
for you.
