To use your Hypertwenty Royal Guards sweatshirt, just put it on and enjoy its comfort. When it's time to clean, turn it inside out and wash it in cold water with similar colors. Only use non - chlorine bleach if necessary. After washing, you can hang it to dry for the best look, or you can tumble dry it on a cool or low - heat setting. Remember, fabric softener can make the colors fade, so don't use it. Also, don't iron or dry clean the sweatshirt to keep it in good condition.
