To use these men's T-shirts, simply put them on and enjoy their comfort. When it's time to clean, machine wash them cold and inside out with similar 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. Remember, fabric softener can make the colors fade, so it's best to skip it. And don't try to iron or dry clean these shirts to keep them in good shape.
