The material seems ok, it's not as heavy as I wanted but it is definitely heavier than other sweatpants.  I am skinny, 5'5" and 105 lbs.  Ordered small, waistband is too tight, and the elastic band keeps twisting around making the sweatpants extra uncomfortable, legs are too short and too big.  I don't care about the legs being big, but then why is the waistband so tight?  Maybe it is sized better in bigger sizes, but if you're small like me and want something comfortable, go for something else.
