Using a soft measuring tape, wrap it around the widest part of your head—approximately 1/8 inch above your ears and across the middle of your forehead, where your hat will naturally rest.
Hold the tape comfortably snug, but not tight. Record your measurement in inches or centimeters, then compare it to our sizing chart.
If your measurement falls between two sizes, we generally recommend selecting the larger size. 
If this is your first hat purchase, you're between sizes, purchasing as a gift, or simply would like a second opinion, we're here to help.
