Using these Soulkr hoodies is simple. Just put them on and enjoy the comfort! For zip up hoodies, use the YKK zipper to open and close. Pullover hoodies slip right over your head. When it comes to cleaning, remember to machine wash them cold and turn them inside out. Wash with similar colors to avoid color transfer. Only use non - chlorine bleach if really needed. After washing, it's best to hang them to dry. If you're in a hurry, you can tumble dry on a cool or low - heat setting. Stay away from fabric softener as it can make the colors fade. Also, don't try to iron or dry clean these hoodies to keep them in great shape.
