OK, call me stupid, but I can't find info on their site about these kilts. I know they are "casual" but I don't see their definition of casual. Are they wool? Are they 4-5 yard? Are they light, medium or heavy weight? Common sense says they are 4-5 yards and light weight. Anyone see somewhere on the site where it tells you? BTW, I really like that Highland Heritage (click on swatch to enlarge for better view). Thanks for any help.
