Store your hat in the box received on purchase and place it somewhere cool. This way your hat will stay free of dust. Every now and then brush the crown and brim with a soft bristled brush. To remove dust, use sticky tape or rollers used for clothes (it does wonders). Do not machine wash or dry clean.

Avoid wearing the hat on rainy days so that your hat will keep its shape and structure. Should the hat get wet, place the hat upside down on a flat dry surface and leave it to dry.
