To determine the size of hat or cap that best fits your head, you should measure your head circumference. To do this you can use a tape measure, place it approximately 1-2 cm (0.5-1 inches) above your eyebrows, where the hat should fit. Make sure the tape is as straight as possible. If you don't have a tape measure you can do this with a string and then measure the piece of string used to measure your head.

If you are not sure which size choose and you are between 2 sizes, we recommend you select the larger one.

Use the following table to determine the size of hat or cap you need once you know your head measurement.
