These shirts are made of a thick, high quality material, and are good for layering - warm enough with a coat on a winter day, but not so warm that you get hot inside. They're comfortable and soft, and flattering in my 3x size. I will warn that, to avoid a bland appearance, the shirt REALLY needs the little "V" solid color at the neckline. For a few of the colors (black/white/etc.), that V is not noticeable. I recommend sticking with the colors where it is; it adds definition and breaks up what would be a monotonous top.
