My fave go-to warm weather kilt is my American Heritage USAK casual. But I've got two other USAK PV Semi-Trad kilts (one from the most recent XMTS tartan run, and a Thompson Grey). All three of them work remarkably well in warmer weather.

I don't know what the USAK casual will be like this winter (the Thompson Grey got a bit nippy in Chicago in the winter, and the casual doesn't even have the weight of the Semi-Trad kilts to keep it down). I expect it will be put away for the winter along about Halloween or so.

And then I'll pull my 3 wool SWK's out of storage.

Ain't life grand?
