About fifteen years ago I brought my Burberry's to a very nice Scottish lady aling with a very heavy dark-tan wool blanket. She used the existing liner to cut a second liner in blanket cloth, which I have since worn aliong with the original liner as my "extreme cold weather" dress coat. It's long, windproof, and has a closed rear vent. The linings can be separated. and the lighter one worn at a hotel as a bathrobe. The only shortcoming is the absence of a substantial collar, which can be overcome by wearing a scarf.
