These shirts should last longer than 6 months before holes start to appear. There must be weakness in the fabric. They are so comfortable  and soft after wash then start to dissolve. I've never seen fabric do this. It's not like they went anywhere but from the bath to bed and no I don't sleep with moths that munch away while I sleep. These are are NOT rips. You can see in the green picture how multiple holes are starting. So darn dissapointed because I thought theses were nice and I bought six of them. This is two of them and I may have to rate the others as they will probably do the same.
