I truly love these. Not only do they keep my legs, and entire body warmer. They also keep my toes warm! Who would have thought that was possible? I walk my dog all winter long. We have an extremely large, dog park by my home. The winter wind whips through there with a bitter bite. My entire life I always layered up with 2 pairs of pants. Not any more. I saw someone up there with a pair of these on. She told me how great they were.
