Using these hoodies is as easy as just putting them on! You can choose between the zip-up style or the pullover style according to your preference. When it comes to maintenance, remember to machine wash them cold and turn them inside out. Wash them with similar colors to avoid color bleeding. Only use non-chlorine bleach if it's really needed. After washing, it's best to hang them dry. If you're in a hurry, you can use the tumble dryer on a cool or low heat setting. But be careful not to 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.
