Using these Soulkr Bonne Power hoodies is easy. Just put them on and enjoy the comfort. 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 it's really needed. After washing, you can hang them to dry for the best results. If you're in a hurry, you can tumble dry on cool or low heat. But don't use fabric softener because it might make the colors fade. Also, don't iron or dry clean these hoodies to keep them in good condition.
