How to use this sweatshirt is simple - just put it on and enjoy its comfort. When it gets dirty, machine wash it cold inside out with similar colored clothes. Only use non - chlorine bleach if it's really needed. After washing, hanging it to dry will give the best results, but you can also use a tumble dryer on a cool or low - heat setting. Remember, using fabric softener can make the colors fade. And don't try to iron or dry clean it, as this might damage the fabric. This way, your sweatshirt will stay in great shape for a long time.
