How to determine your head size?

Use a soft tape and place the tape firmly around your head.  If you have no soft tape, just use a string and measure the string with a ruler.

Tips for resizing your hat

If the hat is too big, for a more precise fit, use a strip of double sided tape and put some foam padding material on one side of the tape and apply the other side of the tape onto the back of the hat. The smaller you want the hat to be, the longer or the thicker the padding has to be.
