These Thunder Soul hoodies are easy to use. Just put them on and enjoy the comfort and style. When it comes to washing, make sure to turn them inside out and wash with similar colors in cold water. If there's a need for bleach, use non-chlorine one. After washing, it's best to hang them to dry. You can also use a dryer on cool or low heat. Remember, fabric softener can make the colors fade, so skip it. And don't try to iron or dry clean these hoodies to keep them in good condition.
