These Teesgeex Flame Fist hoodies are super easy to use. Just put them on and enjoy their comfort. When it comes to washing, remember to turn them inside out and wash in cold water with clothes of similar colors. Only use non - chlorine bleach if really needed. After washing, you can hang them to dry for the best results, or you can use the tumble dryer on a cool or low - heat setting. But don't use fabric softener as it can make the colors fade. And don't iron or dry clean them, as this might damage the fabric and the prints.
