Comfy not too warm
I am 5’9”. and weigh 150 lb The large fits well.  Pants and top are long enough and do not ride up. The medium might also work but I was concerned about the length.  Soft and comfy. Adds a nice layer of warmth but will not keep you warm in minus temps. For me this is a plus since I can feel too warm and uncomfortable very quickly. Love this set.
