Using these men's shirts is easy. Just put them on and enjoy the comfort. When it's time to clean them, machine wash them in cold water, turning them inside out and washing with similar colors. Only use non - chlorine bleach if needed. After washing, you can hang them to dry for the best results, or tumble dry on cool or low heat. Remember, fabric softener can make the colors fade, so don't use it. Also, don't iron or dry clean these shirts to keep them in good condition.
