These Hypertwenty hoodies are super easy to use. Just put them on and enjoy their comfort. When it comes to washing, throw them in the machine on a cold cycle, turn them inside out, and wash with similar colors. Only use non-chlorine bleach if really necessary. After washing, it's best to hang them up to dry. If you're in a hurry, you can use the tumble dryer on a cool or low heat setting. But be careful, fabric softener can make the colors fade. And don't iron or dry clean them to keep them in great shape.
