Using these hoodies is simple. Just put them on and enjoy the comfort. When it's time to clean, remember to machine wash them cold inside out with clothes of similar colors. Only use non - chlorine bleach if necessary. After washing, it's best to hang them to dry, but you can also tumble dry on cool or low heat. Avoid using fabric softener because it can make the colors fade. And don't try to iron or dry clean these hoodies, as it might damage them.
