I purchased this for my husband. The shirt is of good quality, but the size is somewhat off.  Mind you, he's tall and long, but still, the male medium just about fit me. I love the shirt and am thrilled to inherit it, but it should have fit him. He's very slender. This shirt is suited to a short, small "medium" man. I am 5'9" and thin and it fits me (a woman).  Men over 6'1" or with long arms shouldn't bother, even if they normally wear a medium. Otherwise, it's a quality thermal. It's thick, comfortable, and our "holiday black" model has a very practical gray-black threading so it won't show a faded ugly black color ever, however many times it's washed.
