Using these Kingdom Sora hoodies is simple - just put them on and enjoy the comfort. When it's time to clean them, remember to machine wash cold inside out with like colors. Only use non - chlorine bleach if necessary. After washing, hanging them to dry will give the best results, but you can also tumble dry on cool or low heat. Avoid using fabric softener because it can make the colors fade. And don't iron or dry clean the hoodies to keep them in good condition. They come in sizes from S to 4XL, so you can choose the one that fits you best.
