Felt Hats - Keep your hats dust free. We recommend a soft bristle brush for cleaning felt hats. Always brush with the nap in a counter clockwise motion. Ordinary dust marks and smudges may be removed with a hat cleaning sponge. To store your hat, we recommend keeping it in a hat box. Always place the hat upside down on its crown to avoid affecting the shape of the brim. Felt hats were not intended to be worn in the rain. However, if a hat does get wet, flip the sweatband outward and set the hat upside down on its crown to allow it to dry naturally.
