These DinoMike 'Don't Panic' hoodies are super easy to use. Just put them on and enjoy their comfort and style. When it comes to washing, remember to turn them inside out and use cold water. Wash them with similar colors to avoid color bleeding. Only use non-chlorine bleach if really needed. After washing, it's best to hang them to dry, but you can also use the tumble dryer on a cool or low heat setting. Don't use fabric softener as it can make the colors fade. And please don't iron or dry clean these hoodies to keep them in good condition.
