Comfy, but they run very large. I ordered about a size down and could have gone one lower. Haven't tried with jeans yet, just sweats. They seem to stay put & not creep up. They feel more nylon-ish than microfiber. But there is cotton lining in crotch area, so not a problem. I'd like them better if the legs were about an inch longer and the waist didn't come up quite as high, but overall, I like them and would buy again.
