After a single wash, my large t-shirts shrank to the size of a small. Probably the most extreme shrinkage I have ever experienced. By comparison, a similar pack of Fruit of the Loom t-shirts I bought a few years back didn't shrink at all. So I am guessing Hanes uses some kind of truly inferior cotton in this product. In any case, I can't wear them after one wash. Another Goodwill donation I guess.
