To use these men's t-shirts, just put them on and enjoy the comfort. When it comes to washing, remember to use cold water and turn the shirts inside out. Wash them with similar colors to prevent color bleeding. Only use non - chlorine bleach if necessary. For drying, hanging them up is the best option, but you can also tumble dry on a cool or low - heat setting. Don't use fabric softener as it can fade the colors. And never iron or dry clean these shirts to keep them in good condition.
