Remove dust and loose dirt with a soft brush, starting at the left side of the hat and brushing counter clockwise. A lint roll brush works too. Avoid exposing your hat to the heat. Indoor and outdoor. Car windows and enclosed cars in the summer can damage the hat. The combination of the heat and perspiration will shrink the sweatband. If your hat gets wet, shake off the excess water. This will allow the hat to dry naturally. To put on and remove your hat, hold the brim in front and back, handle the crown as little as possible. If you follow these important instructions your hat will last a lifetime.
