I don't agree with the "lighter; cheaper looking" thought either. I think Cavscout hit that issue on the head. I have a 4 yd. box pleat in 16 oz. strome (by this guy ) sorry Matt LOL. and don't forsee any problems with it in the summer heat (SE NM = HOOOOOOOT.) I also have a 5 yd. knife pleated kilt made from 11 oz. wool, that I'm sure will get a lot of wear this summer. I did tend to shy from it this winter. I also have to throw in a voice of support for the PV tartans. I have three USA Kilts casuals and wear them regularly. They will undoubtedly be a summer favorite of mine. I had an acrylic kilt last summer that I have since sold. I've gotta say, that sucker was smoldering in the Arizona heat. Wore it once on that trip and not again. These are my megar experiences with the elements and kilts...
