These DinoMike hoodies are super easy to use. Just put them on and enjoy the comfort. When it comes to cleaning, you can machine wash them in cold water. Make sure to turn them inside out and wash with similar colors. Only use non - chlorine bleach if you really need to. 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. Remember, fabric softener can make the colors fade, so don't use it. Also, don't iron or dry clean these hoodies to keep them in good condition for a long time.
