These Hell Gym hoodies are easy to use. Just put them on and head to the gym or wherever you want to go. When it comes to washing, use cold water and turn them inside out. This helps protect the prints and keeps the colors vibrant. Wash them with similar colors to prevent color bleeding. Only use non - chlorine bleach if there are tough stains. After washing, hanging them to dry is the best option as it maintains the shape of the hoodie. But if you're in a hurry, you can tumble - dry on cool or low heat. Remember, fabric softener can fade the colors, so skip it. And never iron or dry - clean these hoodies as it may damage the fabric and the prints.
