Using this T - shirt is as easy as just putting it on! It's suitable for both men and women. When it comes to maintenance, you can simply toss it in the washing machine. But to keep it in good shape, avoid using extremely high - heat settings. As for the colors, remember that the heather ones have a blend of polyester, so they might hold up a bit differently than the solid cotton ones. And be aware that the color in the preview images might not be an exact match to the real thing because of lighting during the photo shoot or your monitor.
