These Hypertwenty hoodies are super easy to use. Just put them on and enjoy their comfort. When it's time to clean them, remember to machine wash in cold water, turning them inside out and washing with similar colors. Only use non - chlorine bleach if really needed. After washing, you can either hang them to dry for the best result or tumble dry on cool or low heat. Don't use fabric softener because it can make the colors fade. Also, don't iron or dry clean these hoodies to keep them in good condition.
