Excellent non-constricting fit made from a material that stretches with the body as you move: keeps the body warm and dry at a great value. Yes, there are more stylish (and expensive) high-tech thermals out there (including those from TSLA, which I also own). No, you don't always need all those extra bells and whistles. If you want something comfortable to wear under your clothes to keep you warm on a very cold day, this is all you need to wear and spend.
