These Blue Shell hoodies are really easy to use. Just put them on and feel the comfort! When it comes to washing, remember to turn them inside out and wash them in cold water with similar colors. Only use non - chlorine bleach if it's really dirty. After washing, hanging them to dry is the best way to keep them in good 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 don't try to iron or dry - clean these hoodies, as it could damage them. Enjoy your stylish and comfortable Blue Shell hoodies!
