I'd suggest a 4 yard box pleated kilt in the Armstrong tartan. You can get a kilt made from the highest quality heavy weight wool, but it's still lighter than a "tank" and very comfortable to wear. Here's a pic of my Armstrong box pelated kilt:


Cost would be $350. Right now I have about a 5 month wait for order completion (trying my best to get that down, but there are only so many hours in the day!).

If you wanted something in a hurry, we can have a "casual" kilt made for you. You can still get really nice heavy weight wool for only $345. But this will be knife pleated, made from 4 yards of cloth, and machine sewn. It will have all the comfort benefits of a 4 yard kilt, but the construction is not quite as nice and neat as the box pleated kilts, which I hand sew. The turn around time on one of these is usually 2 months, though there is a rush option if you need it faster.

Here's a pic of one in the ancient Armstrong tartan:
