Pretty cool. I have read that a lot of that type of armor was probably leather because the laminated linnen would take so much time both in relation to weaving the cloth and gluing up the laminations. Leather would have been much cheaper, faster and easier to work with, and provides pretty much equal protection. There is a book by John Watterer called "leather and the warrior" that speculates that much of the medieval armor usually assumed to be metal plate from pictures and sculptures, is actually hardened leather.
