Using these t-shirts is easy - just put them on and enjoy the comfort! When it's time to clean, remember to machine wash them cold, inside out with similar colors. Only use non - chlorine bleach if necessary. For the best look and to keep the fabric in good shape, hang them to dry. If you're in a hurry, you can tumble dry on cool or low heat. But be careful not to use fabric softener as it can make the colors fade. Also, don't iron or dry clean these shirts to avoid damaging the material.
