This XENOS long - sleeve crewneck sweatshirt is super easy to use. Just put it on and enjoy your day. When it comes to washing, turn it inside out and toss it in the machine on a cold cycle with clothes of similar colors. If it gets dirty, you can use non - chlorine bleach, but only when really needed. After washing, hanging it to dry is the best way to keep it in great shape, but you can also use the tumble dryer on a cool or low - heat setting. Don't use fabric softener as it might make the colors fade. And never iron or dry - clean this shirt to avoid damaging it.
