Using these men's t - shirts and premium t - shirts is easy. Just put them on and enjoy the comfort. When it comes to washing, set your machine to cold and turn the shirts inside out. Wash them with clothes of similar colors. Only use non - chlorine bleach if there are stains. After washing, it's best to hang them to dry. But if you're in a hurry, you can tumble dry on cool or low heat. Remember, fabric softener can make the colors fade, so don't use it. And stay away from ironing and dry cleaning to keep the shirts in good shape.
