How to use your Hypertwenty's Treasure Spear Hunters sweatshirt: Just put it on and flaunt your style! 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 really needed. After washing, hanging it to dry will keep it in top shape, but you can also use the tumble dryer on cool or low heat. Remember, fabric softener can make the colors fade, so skip it. And never iron or dry clean your sweatshirt to keep it looking great for a long time.
