If I were to go camping kilted, I'd leave it to the very-washable Utilitkilt style of kilt only.

They aren't flammable, don't melt, don't snag, and you can wash them. When I go camping, I'm off to the lake, tromping through the woods. building fires, climbing mountains (or hills, whatever), etc. I wouldn't want a wool kilt up there with me.
