I'll add my endorsement for USAK's. I have 4, 3 casuals and 1 semi-trad. I love them. Just keep the torso warm. I made the mistake of wearing my USAK Ireland's National to Oktoberfest here a few weeks ago with just a short sleeve shirt and sandals. Now the fest was at a park on the water and a cold front moved through that evening. With the wind, a little higher humidity, and the falling temps (only down to 50 or so), I got cold, to the point of shivering. BUT, that was because my torso was losing heat so fast, I could not keep warm. If I had worn a long sleeve shirt, or even had a sweatshirt or such to put on I would have been fine. It wasn't what was under the kilt that was cold!
