Super thick definitely warm and feels comfortable. I bought these for my daughter because they are the only ones I could find that looked very fat. I would happily buy duplicates if they come back on sale, they roll up easily and are very long so you can adjust the size. They are very large on my daughter, she is below average but they stay in the sense that it is an elastic waistband. So you don't have to worry about her growing out of it for a while, maybe even surviving two winters with it. They are expensive but worth it, I live in a very snowy town.
