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 (the 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
  • Roll is 60 cm / 23.6 inches in length 

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

  • Full-price items can be returned for a refund, credit note or exchange within 14 days of purchase, including those purchased using a welcome discount code.

    Great option!

    Good product to fit perfectly if you’re between 2 sizes and during windy days!
