Large/X-Large 23" to 23 7/8" 7 3/8" to 7 5/8"

To determine your hat size, measure the circumference around your head, keeping the tape level and firm, across the temples and above the eyebrow ridges. Once you've got your measurement, check the size chart to see what size is best for you. For in-between measurements, use the next size up.
