Free Size: If a hat lists F size, it is a 'one-size-fits-all' hat. It will fit sizes from 53cm up to 62cm.

WHAT’S MY SIZE?

The best way to determine what your size is to measure the circumference of your head where you want to wear it. Please refer to the sizing chart on the product page before you measure.

MEASURING YOUR HEAD

Measure the circumference of your head approximately 2.5cm (1") below the hairline to the back of the head.

If you’re unsure or in-between sizes, we recommend sizing up and adding some hat fillers or utilizing the adjustable sweatband for the perfect fit.
