I've worn a USA casual out in cold, windy Chicago weather...note that I was wearing an "underkilt climate reinforcement" garment (okay...some reasonably sturdy boxer briefs from Target...I recommend them to those of us who feel the need) and my kilt pin is pewter and relatively heavy. It has been noted here that if you have the torso, head and feet dressed warmly, your kilt area stays pretty comfortable and I agree with that. In my case, this was a casual...I'd expect that the semi-trads would be even warmer. Lots of our kilties that live in the way-warmer climes of the Southern and Southwestern USA are USA Kilts hardcores....they praise their comfort in the heat. I've worn the USA casual around here in warm weather and it's been fine but it's also proved its worth in the cold.

You certainly have a couple of other options for a quick and reasonably priced kilt but USA offers such a great variety of tartans in that PV that it's hard to resist.
