I'll second (3rd 4th 5th?) the utility of the Asian PV kilts. They advertise as Poly Viscose, and I have not done, nor seen, any tests to prove them to be otherwise. I have one from buyakilt.com which is a sister company to MacDonald sporrans. They provided prompt service with good email follow up through the process. They have a good offering of tartans, both clan and universal. I have one in Scottish National tartan that I wear for rugged use, and it serves me just fine for that purpose.

As others have said, they are coarser to the hand than Marton Mills PV, and they tend to be pleated to the "whatever" but at the prices offered, and for their intended use, they are hard to beat.

I also have two Marton Mills PV kilts from USAKilts and Skye Highland Outfitters, both of which charge accordingly for the higher quality material and labor, but are excellent values as well

Good luck in what ever you choose!
