I've heard from a few members that their shirts have been ruined in the wash - the screen printing disintegrates. I have tested this myself and found it happens on some shirts but not all shirts.
Please let me know if your shirt is one of the affected ones. Their was an issue with the ink dryer when they printed some of the shirts and they have offered to replace all of the affected shirts. Please let me know if you are one of those. The only way to tell is to wash it.
It doesn't matter if the shirts were washed inside out or not, they can peel. Please see the attached.
