Using these men's T - shirts is as easy as putting them on. Just pick the right size for you, either from the regular T - shirts that range from S to 6XL or the premium ones from S to 3XL. When it's time to clean them, remember to machine wash cold, turn them inside out and wash with clothes of similar colors. Only use non - chlorine bleach if really needed. You can hang them to dry for the best look, but if you're in a hurry, tumble dry on cool or low heat. Be careful not to use fabric softener as it can make the colors fade. And don't try to iron or dry clean these shirts, as it might damage the fabric.
