I haven't worn leggings in years, but I really wanted fleece-lined ones--it gets cold here--so I gave these a shot. Yes, they do smell a bit gasoline-y, but the fit is so comfy, and they're so well made--not going to stretch out for sure--that I can forgive them. However--a warning--- I'm 5'1" and 105 lbs, and I bought the MD/LG because I have a bit of a tummy and no waist to speak of, and they fit me perfectly. I can't imagine a true MD/LG getting into these. One other thing: the pair I got were not in brand-new packaging - possibly having been previously purchased by a MD/LG - and the plastic had been ripped open and sketchily retaped. Kind of a bummer, but hey, I've returned stuff (except I'm much more courteous about opening and resealing). Haven't worn these yet but they look fabulous with all my boots!
They are comfy, soft and they feel thick. I like them, they don't have a sheer look and they don't look as they would get any lines. I think the price may be steep but the quality is really good. I gave it an overall 4 because I haven't tried them out in the cold.
