These 'Trust No Atom' hoodies are super easy to use. Just put them on and enjoy the comfort and style. When it comes to cleaning, machine wash them cold inside out with clothes of similar colors. Only use non - chlorine bleach if really needed. After washing, hanging them to dry will give the best results, but you can also use a tumble dryer on cool or low heat. Remember, fabric softener can make the colors fade, so skip it. And don't try to iron or dry clean these hoodies to keep them in good shape.
