These jeans are lined with flannel and they are exactly what I was looking for to keep warm. I live near the windy city of Chicago,where it is cold @ 8 months out of the year, so when going outside  walking the dogs in winter months, these jeans keep you warm.  The size was good, they fit according to what they say. I usually wear a size 6 , but ordered a size 8 in case of shrinkage and I didn't want tight fitting jeans for walking in outside in the cold.  So since I like to wear things a little baggy, these are a great fit. The only thing I wish, since I am only 5ft. tall, is that they were not so long. Maybe they can make them available in Short.  The quality was very good and they are a great deal on Amazon, I think.  I purchased another brand that was quite a bit more expensive than these jeans, and I think these are even a little bit nicer quality than they were.  So for the money they are a great buy!  I would def definitely recommend these!
