If your hat isn't a snug fit, the hat filler is for you... Made of foam cushioning, the adhesive filler sticks to the inside of your hat for a better and smaller fit. Reduces your hat size by approximately 1-2.5 cm. Sold as singles. Each filler is about 6 inches long. 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, hat filler is applied to the inside of the hat crown, under the sweatband lining. We recommend replacing your hat filler after prolonged use.
