These are sturdy flannel lined jeans that keep you warm but don't overheat.  Fit is true to size, relaxed so don't think that these jeans are going to be "skinny".  I wear them to work outside, and to walk outside.  I so not like cold weather and these jeans are perfect to keep you warm and cozy.  At the same time, you can wear them inside and not feel that you need to rip them off for something cooler.  As we are all more conscious of the price of heating, these jeans are attractive and a perfect answer.  Just great.
