Was looking for a black wrinkle-free shirt for work and stumbled across this item.  It is poplin, so the material is very thin.  It breathes nicely, though, and doesn't lock in heat like some of the thicker wrinkle-free shirts.  I ordered for tall, because I have shirt-tail issues, and the length is good.  The only thing I don't like about the shirt is that the cuff has no second button to keep the enclosure above the cuff closed.  Other than that, I love the shirt and find it to be comfortable.
