To use these t-shirts, simply put them on and enjoy their comfort. When it's time to wash them, remember to machine wash cold, turn them inside out, and wash with like colors. Only use non-chlorine bleach if needed. After washing, it's best to hang them dry for the best results, but you can also tumble dry with cool or low heat. Don't use fabric softener as it can make the colors fade. And never iron or dry clean these shirts to keep them in good condition.
