Additional tips: 1  To make sure your hat will be a perfect fit, you can place the strip behind the band without taping it down and try it on first for size. 2  I recommend that you place the foam strip on the back of the hat.3  If your hat is really big, you can place 2 strips on the sides of the hat. Itâs about 3/4 inches in this hat. 2  Youâll be going to be placing a strip of foam behind the band, so cut your foam strip a little bit slimmer than the band. 3  Apply double sided tape to just one side of the foam strip. 4  Take your hat and peel back the inner band at the back of the hat.
Sizes, even though they do vary depending on the hat maker, are technically universal. You may refer to the sizing chart above if you need to convert a medium to an actual hat size. SIZING TIPS: Small is usually 55cm, medium is usually 57cm, Large is usually 59cm, X-Large is usually 61cm and 2X-Large is usually 63cm. If you fall in between these sizes, you may want to look at our SWEAT BAND which will take a hat down approx. 1cm. Brands from different countries, use different sizing.
