Measure all the way around your head with a soft tape measure positioned mid-forehead and just above the ears (where you’d like the hat to sit).
In case you don’t have a tape measure, you can also use a piece of string and measure the distance with a ruler afterwards.
Find your measurement on the size chart.
If you’re between sizes, please email me at firstname.lastname@example.org. In some instances, the hat can be adjusted to size up or down.
