I have worn these a handful of times and am very pleased so far. I live in MN and have been wearing these as an outer layer for trail running. They have kept me warm in single digit temps. I also intend to wear them for cross country skiing. They run big. I am 5'8", 140lbs and originally bought a medium. I returned for a small and the small is still roomy for me. That said, since I'm mostly using them as an outer layer I kept them. My only complaint is I noticed the material started to pile a little bit, so I'm curious to see if that continues.
