I received these as a christmas gift. they are really cozy: warm, soft and super comfortable. however, they stretch out a lot, as there is no drawstring or elastic on the waist band. this leads them to poof out a lot and i have to keep pulling them up. this is fine for hanging out around the house, but not if you want to wear them out and about. i'm keeping them because they're so comfortable, but beware how much they stretch. (i am 5'6", 130 lbs and the size small fits well).
