I have had this jacket for about a year now. I completely agree that the sleeves are very warm. The lining of the sleeves also helps to prevent bunching up of your shirt sleeves or sweater when putting the jacket on.

The sleeves are not lined with sheepskin. They are still very warm, but have a smooth polyester acetate lining for increased mobility.
