To use this sweatshirt, simply put it on and enjoy its comfort. When it comes to washing, remember to turn it inside out and wash it in cold water with similar colors. Only use non - chlorine bleach if it's really dirty. After washing, hanging it to dry is the best option. But if you're in a hurry, you can tumble dry it on a cool or low - heat setting. Just be careful not to use fabric softener as it can make the colors fade. And never iron or dry clean this sweatshirt to keep it in good shape.
