If your hat isn't a snug fit, the hat filler is for you!
Made of foam cushioning, this adhesive filler sticks to the inside of your hat (wool OR straw) for a better & smaller fit. Reduces hat size by approximately 1-2.5 cm. 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.
Note: Apply to the inside of the hat crown, under the sweatband lining.
