Using these men's t - shirts is easy. Just put them on and enjoy the comfort. When it's time to clean, machine wash them cold inside out with similar colors. Only use non - chlorine bleach if necessary. After washing, it's best to hang them dry. If you're in a hurry, you can tumble dry on cool or low heat. Remember, fabric softener might make the colors fade, so avoid it. And don't try to iron or dry clean these shirts, as it could damage them.
