A bit of reference toward the current ideer... staring in the iheadlights... ending up on the iroad as iroadkill.
I've been thinking about the heavy use of furs to help insilate the wearers from the cold, it will be almost necessary for anyone in these climates to have heavy layers of clothes, Metal armor will definately be of hinderance because it will not only keep from insulation but in some aspect it can amplify the cold. But this doesn't mean that the metal can't be interweaved into the furs and clothes. just as long as the under layers aren't effected.
Just a couple thoughts...
