This review is for a long sleeve waffle jersey shirt. It has 3 buttons on the front and reminds me of the thermal underwear of the 1970's but is much thinner. One of the photos is looking out my window, through my shirt, it's very, very thin. It will work in summer, but in hot weather you might look a bit weird wearing this shirt. But I'm afraid it won't do much to keep you warm in cold weather. I think for fashion, under another shirt, it will look good and not add too much warmth. Despite the weight of the fabric, this is a good shirt. The color is pleasant, well sewn, fits as it should. As a fashion item that would be nice, but I think I'm more into functionality than fashion.
