I smoke cigars and feel safer in a wool kilt than an acrylic one. I've had embers hit my wool kilt, brushed the off and no major holes/damage. I've had the same thing happen in my acrylic and holes all over and some melted mass hit my legs. I have this nightmare of smoking a cigar in one of my acrylics, having an ember hit it , and the hole thing going up in flames. Not a pleasant thought. Like I said, I feel safer cigar smoking in my wools.
