Using these Arinesart hoodies is as easy as putting on any regular hoodie. Just choose the size that fits you best, whether it's a zip - up or a pullover. When it comes to cleaning, remember to machine wash them cold and turn them inside out. Wash them with similar colors to avoid color bleeding. Only use non - chlorine bleach if needed. After washing, hanging them to dry is the best way to keep them in good shape, but you can also tumble dry on a cool or low - heat setting. Don't use fabric softener because it might make the colors fade. And never iron or dry clean these hoodies to ensure their long - lasting quality.
