Heads come in all different shapes and sizes. Plus, we all like to wear our hat differently!
To make sure you have your correct hat size, you'll need to measure the circumference of your head. Do this by wrapping a measuring tape around the crown of your head, placing the tape one to two fingers width above your eyebrows and one finger above your ears. Alternatively, use a piece of string and then measure the length.
Whatever your measurement, add 1cm to determine your correct hat size. eg head measurement of 57cm wears size 58 hat. Whilst the leather sweatband inside your hat will help mould to your head over time, hats do not stretch.
Look to the size up for in-between (half centimeter) sizing and place a piece of foam tape underneath the brim until you've worn in your hat.
There are two ways people most commonly wear a hat:
Flat on top of your head, one to two fingers width above the eyebrows
Tipped back on the crown of your head, so the brim sits just at the start of your hairline
