To use these XENOS hoodies, just put them on and enjoy the comfort. For zip-up hoodies, you can easily zip and unzip as needed. For pullover hoodies, pull them over your head. When it comes to washing, always machine wash cold and turn them inside out. Wash with like colors to prevent color bleeding. Only use non-chlorine bleach if really necessary. After washing, hanging them to dry is the best way to keep them in good shape. If you're in a hurry, you can tumble dry with cool or low heat. Remember, fabric softener can make the colors fade, so don't use it. And never iron or dry clean these hoodies to avoid damage.
