HOW TO MEASURE YOUR HEAD
Kakadu hats - or Mates as we often call them - come in all shapes and sizes so you're sure to find a Mate that suits you.
But first things first, lets determine your correct size. Remember you want comfortably firm
Wrap a tape measure or a piece of string (if you use string, you'll need a ruler as well) around your head so that it is above your eyebrows and a 1cm / half and inch above your ears. No need to pull too tight - remember you want your hat to be comfy!
Follow the size guide below to help determine your size. There are some slight variations in size depending on the fabric used for the hat - thicker materials mean the hat fit will be a bit tighter and thin fabrics a bit touch looser
