Well, there you go Tobus. I guess the construction questions are better left to the maker and expert, Robert. All I know is how much fabric I ordered as directed by Robert That, and the fact that I couldn't be happier with this kilt. But you would be right though; a 16oz wool tank would be even more beastly than this kilt, in terms of fabric usage. And although this kilt has superb swish, I wouldn't doubt if the swish of a wool tank would, at the least, be just as good.

Cheers,
