This Hypertwenty sweatshirt is super easy to use. Just put it on and enjoy its comfort all day. When it comes to washing, simply toss it in the washing machine on a cold cycle. Make sure to turn it inside out and wash it with similar colors to keep it looking great. Only use non - chlorine bleach if it gets really dirty. After washing, you can either hang it to dry for the best results or use the tumble dryer on a cool or low - heat setting. Don't use fabric softener as it might fade the color. And never iron or dry clean this sweatshirt to keep it in good condition.
