Using these hoodies is as easy as putting them on! They're great for casual outings, stargazing nights, or just lounging at home. When it comes to maintenance, always remember to machine wash them cold and inside out with similar colors. Only use non - chlorine bleach if really needed. After washing, hanging them to dry is the best option, but you can also use a tumble dryer on a cool or low - heat setting. Keep in mind that fabric softener can make the colors fade, so skip it. And don't iron or dry clean these hoodies to keep them in top shape.
