Using these Donnie Mayhem hoodies is easy. Just put them on and enjoy the comfort. When it comes to cleaning, machine wash them cold and turn them inside out. Wash with like colors to prevent color bleeding. Only use non - chlorine bleach if necessary. After washing, hanging them to dry is the best way to keep their shape and color. If you're in a hurry, you can tumble dry on cool or low heat. But don't use fabric softener as it can make the colors fade. And remember, don't iron or dry clean these hoodies to keep them in good condition.
