Exactly what does that mean? Can I sleep while I'm feeding the cattle? Where did they come up with this name? If you watch TV I'm sure you have seen them advertised. I wear jeans almost all the time except to sleep. I have several different colors but not much on changing with the style from boot cut to slim and back again but guess the ads played on my jean loving brain. It took so long for them to get here I was beginning to worry about giving my credit card number out but they are here now and I do like them so far. I happened to click on a site where people were discussing why you should not wear them. One person said if you wear pajama jeans to Wal*Mart the first thing you know you will be wearing your robe and houseshoes there. Well I think not. Other then being thick and soft they look like jeans to me. I got me some pajama jeans and I'm gonna wear 'em.
