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.
