Using these Blue Doom hoodies is easy. Just put them on and enjoy the comfort and style. When it's time to clean them, machine wash cold inside out with clothes of similar colors. If they need a bit of bleaching, use non - chlorine bleach. After washing, hanging them to dry will give the best results, but you can also tumble dry 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 as it might damage them. Also, with the sizes ranging from S to 4XL, you can find the perfect fit for you.
