What I do like is the shape and warmth. What I don't care for is that it is a bit too thick for my liking. Honestly, I can get the same warmth with a much thinner polypropylene thermal that doesn't cost quite as much. Also, from the product description, which described bottoms as well, I felt a little mislead into thinking the  bottoms were included, which apparently they are not. So I thought it was a bit overpriced for just the top. Would much rather have polypropylene, which surprisingly cost less.
