Kilt material experiences

[billsides]

I have kilts of many types and have worn kilts for ages. Now retired, I am wearing out tired old cheap Pakistani kilts in my garage (I restore old cars which often involves welding and grinding) so am concerned about flammability and may replace them with working kilts. Most seem safe enough but are light. I am not very interested in pockets, loops and the like appendages but do like working free, so weight is of interest. I have a 6 yard 9 oz woollen kilt that is hopeless outdoors and all work kilts found to date are no heavier. I prefer traditional kilt designs. Camo should show stains less and be cheaper and most be as safe as wool so interest me. Decent pleats are desirable but have significant uplift in winds.Camo fabrics all seem light with obvious implications. That is my concern. Maybe somebody has experience with these lighter materials or knows where heavier materials are available.
