You can prolong the life of your bonnet by hand washing it, or placing it in a laundry bag before putting it in the washer. If hand washing, lay your bonnet flat to dry. If using the washer, place your bonnet inside the protective bag and add it to the washer. Once your wash is complete, leave your bonnet in the protective bag and place it in the dryer. Remove your bonnet from the protective bag and begin use!
