I received one of these about 15 years ago and still wear it around the house in the Winter, even though it's now in tatters (I wore it a lot). I just bought another (with several more purchases pending) and can say without a doubt it's one of the most comfortable articles of clothing I've ever worn.
Our adult son has had one for many years - still okay, but getting a bit dull. So I've bought him a new one to wear to the UNM womens basketball games. I know it'll make him happy.
