The G.A.B. Hat Filler is the perfect solution for achieving a snug fit for your hat! The Hat Fillers are made of high-quality foam that is both durable and comfortable, and this four pack can be used to adjust the size of your hat to your liking. Simply stick them to the inside of your hat using the rear adhesive strip, or you can slot them behind the band, and place as many as you like around the inside of your hat to get the perfect fit.

If you’re using them on an Akubra hat, avoid sticking them on the inner leather hat-band and instead stick them to the felt behind the hat-band. You don’t need to use the adhesive if you would prefer to remove it at a later stage.
