First, they have good heavy fabric, but the neck opening is too small, they should be about an inch larger in the neck opening. Too bad because I like the fit of the whole shirt and not the neckline. I had to return them for this reason, because they basically choked me. I've seen many other reviews saying the same thing but thought I'd give it a try, anyway this turned out to be the exact problem I was having. The manufacturer should read the reviews and adjust the shirts accordingly, then there would not be so many returns.
