These Hypertwenty hoodies are super easy to use. Just put them on and enjoy! When it's time to clean them, throw them in the washing machine on a cold cycle. Make sure to turn them inside out and wash with similar colors. If they need a bit of a bleach, only use non - chlorine bleach. After washing, hanging them to dry is the best way to keep them in top shape, but you can also use the tumble dryer on a cool or low - heat setting. Remember, fabric softener can make the colors fade, so skip it. And don't try to iron or dry clean these hoodies. They'll last you a long time if you follow these simple steps.
