To use this Zero Suit Dread sweatshirt, just put it on and enjoy the comfort. When it's time to clean, machine wash it cold, turning it inside out and washing with similar colors. Only use non - chlorine bleach if there are stains. After washing, you can either hang it to dry for the best result or tumble dry it on cool or low heat. Remember, don't use fabric softener as it might make the colors fade. Also, avoid ironing and dry cleaning to keep the sweatshirt in good condition.
