I really liked these when I first got them. They are warm and long enough for me with boots on (I'm very tall). The fabric feels thick and you can't see through it and feels silky soft. The wide waistband is comfortable and stays up.
However, after about 3 months of wearing them once a week, washing in cold water with liquid detergent and dried on a rack, they started to have a lot of pilling on the surface. Now, five months after purchase, I wouldn't wear these in public. They look terrible.
