How to use this sweatshirt? Just put it on and show off your 'Don't Skip Leg Day' spirit! When it comes to washing, turn it inside out and wash it in cold water with similar colors. Only use non - chlorine bleach if it gets really dirty. After washing, hanging it to dry will keep it in great shape. You can also use the cool or low - heat setting on your dryer. Remember, fabric softener can fade the colors, so skip it. And don't try to iron or dry clean this sweatshirt, as it may damage the material.
