These Adho1982 Kupocket hoodies are super easy to use. Just put them on and enjoy the comfort. For zip-up hoodies, use the YKK zipper to open and close. When it comes to washing, machine wash them cold inside out with similar colors. If there's a stain, you can use non-chlorine bleach. After washing, it's best to hang them dry. But if you're in a hurry, you can tumble dry on cool or low heat. Remember, don't use fabric softener as it can make the colors fade. Also, stay away from ironing and dry cleaning to keep your hoodie in top shape.
