Definitely thinner cloth than a no-wrinkle shirt you would buy for twice the price at a men's store, like Jos. Bank. So thin that I won't get away without an undershirt as I did sometimes with my more expensive shirts. That was probably a bad habit, anyway. Sizing info accurate (I'm used to more finer sizing as one sees on the more expensive shirts -- the rougher sizing here is close enough for me). For the price, 5 stars.
