I don't know if the troops still do it, but in the army back in 63 the local tailors would make a decent coat for a soldier if he supplied him with the material of a ponch outer, and blanket inner. Didn't cost much either. It surprised me that the brass didn't seem to mind the non reg attir either. Probably because where they were used most was in the woods on maneuvers.
But it occured to me that in the worst survivalist condition in the coldest winter, the old inside out Inuit carribou two piece suit would be best. I heard the Inuit wore nothing else under them either. You'd a thought the Franklin expedition would have learned from them. They look like hell with the skin turned outward.
Maybe one day I'll plop a carcas on the living floor and get my wife to work the hide and sew one togeather.
Looks like I'm gonna be freezing.
