To use these men's T-shirts and premium T-shirts, simply put them on and enjoy their comfort. When it's time to clean them, machine wash cold inside out with similar colors. Only use non - chlorine bleach if needed. Hang them to dry for the best look, or you can tumble dry on cool/low heat. Be careful not to use fabric softener as it can make the colors fade. And remember, don't iron or dry clean these shirts to keep them in good condition.
