This Carhartt is very warm, lined with the sherpa, but it's not lined in the arms, only the torso and back and the hat.
I wish the arms were lined as well, but it's still warm. It's a lot shorter than I expected. When I raise my arms up, I don't have an extra long torso, and it's noticeably short when I sit or reach for something.
I would raise a flag of caution if you have a long torso or long arms, I do have slightly long arms and it just barely covers mine.
