These 'Soul of the Experiment' hoodies are super easy to use. Just put them on and enjoy the comfort and style. 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 needed. You can either hang them to dry for the best results or use the tumble dry option with cool or low heat. Avoid using fabric softener as it can make the colors fade. And don't try to iron or dry clean these hoodies, as it might damage the material.
