I bought these Sherpa lined sweat pants because I wanted to have something really warm to wear while out shoveling snow, or just having to go out in really cold weather. I had better luck shopping for men's than women's which I sometimes do because I'm tall and like certain clothes to be baggy. I have fibromyalgia and chronic pain that cause me to have a hightened sensitivity to the cold. These sweat pants really help shield the cold. They run true to size, but all the warm material makes them a little heavy. Definitely worth it to keep warm.
