I received an e-mail from Burnett's and Struth just the other day with the information of the Bilt Kilt website. I've emailed them with some questions about the tartan versions of the Bilt Kilt (to wit, verification that the tartan "material" is indeed wool, the method of fastening/closure, and whether the tartan versions have extra reinforcement, vice the poly-cotton/twill versions).

You may stone me for a heretic, but I am mightily tempted by both the "inverse pleat" and box pleat versions of the tartan Bilt Kilts.
