How to use these hoodies is easy - just put them on and enjoy the comfort and style. When it comes to washing, make sure to turn them inside out and wash them in cold water with similar colors. Only use non-chlorine bleach if necessary. After washing, hanging them to dry is the best option, but you can also tumble dry on a cool or low heat setting. Remember, fabric softener can make the colors fade, so it's best to avoid it. And don't try to iron or dry clean these hoodies as it might damage them.
