We advise to keep away from direct sunlight when storing. Keeping your hat clean. Shake off excess water and leave to dry slowly indoors. Do not place on or near direct heat as this may cause it to misshape. We recommend using a lint clothes roller to remove any dust or dirt. For stubborn marks, a damp sponge can be used or alternatively a hat brush. If dealing with mud please allow the mud to dry first before trying to clean.
