Using a measuring tape, measure around your head above your ears where you would wear
your hat. Use the chart on this page to determine your size.
If your head size falls in between two sizes we strongly recommend that you choose the
larger of the two sizes. You’ll find the hat will be more comfortable. A small piece of foam
behind the sweatband can make a large hat perfect.
