Now here this!  If you live in a colder climate place and survive on a wood stove or need something to keep your legs warm under your skirt or use as pajamas, these are excellent, I have a pair on right now.  Plenty of length in the legs, fit so well, not to tight and are so soft.  I've bought three of these because they are just so toasty in a cold house.  The price is excellent too.  Highly recommended folks!
