These San Dimas High School hoodies are easy to use. Just put them on and enjoy! When it comes to washing, machine wash them cold and turn them inside out. Wash them with similar colors to keep the prints and colors looking good. Only use non - chlorine bleach if necessary. After washing, it's best to hang them to dry. If you're in a hurry, you can tumble dry on cool or low heat. Don't use fabric softener as it might make the colors fade. Also, don't iron or dry clean these hoodies to keep their quality and shape.
