Well made tights.  I've used it a whole season now and have had no problems.  Washes up well and stays "lofty" and warm.  They would get 5 stars if they were just slightly longer in the leg.  I purchased the "tall" size, but I still had to open the stitching at the toes to get enough "give" to keep from feeling like they were coming down.  No problem because I use warmer socks anyways, but would be of a concern if you were going to use them under dress slacks or something.
