The head wrap seems interesting. May have to give it a try. I've used shemaughs in warm weather to good effect.

Mackinaw coat.jpg

I've been thinking a mackinaw coat similar to this one, cut to kilt length would make a very nice winter coat for the kilted man. I recall seeing one in waxed cotton cloth with a wool, I believe, lining. Panther Primitives did sell waxed cloth by the yard. Maybe they still do. A kilt coat with Carhartt-ish properties could be made, but in style more compatible with a kilt.
