Using these men's shirts is as easy as putting them on and enjoying the comfort. When it comes to washing, just toss them in the washing machine on a cold setting. Make sure to turn them inside out and wash with similar colors to keep them looking great. If they get dirty and need bleaching, only use non - chlorine bleach. After washing, you can hang them to dry for the best results, but if you're in a hurry, you can tumble dry them on a cool or low - heat setting. Remember, fabric softener can make the colors fade, so skip it. Also, don't iron or dry clean these shirts to maintain their quality and shape.
