How to use: Just put on these cool men's t-shirts and you're ready to go! Whether you're going out or relaxing at home, they'll keep you comfortable. For washing, turn the shirts inside out and wash them in cold water with similar colors. Only use non - chlorine bleach if necessary. After washing, it's best to hang them dry. If you're in a hurry, you can use the cool or low - heat setting in the dryer. Don't use fabric softener because it might make the colors fade. And remember, don't iron or dry clean these shirts to keep them in good condition.
