I love these.  i wear them to bed when it is very cold in the house in winter.  i wear them en route to the YMCA on cold winter mornings, and i even work out in them, even though they are very warm.  I wear them under my jeans and my legs are not shocked at the cold when i get in the cold car, or walk from building to building in cold wind.  Soft and comfy.  I had purchased a pair at a sporting goods store.  I was pleased to purchase them from Amazon since i needed another pair.  I just love them.
