If your hat isn't a snug fit, this hat filler is for you...Made of foam cushioning, the adhesive filler sticks to the inside of your hat, wool or straw, for a better and smaller fit. Reduces the hat size by approximately 0.5-1" and can be used the whole way around your hat or just partially, if you are only wanting to reduce your hat size by a small amount.

Please note: filler is applied to the inside of the hat crown, under the sweatband lining.
