All I know, is that my Blackwatch PV kilt (same as the Canadian material) is 2 years old, and my MacKenzie and Royal Stewart are a 1-2 years old, and none of them are showing any signs of wear or tear, and I beat the sh!t out of these things regularly. Must be the workmanship.

I won't compare PV to a good wool for duarability, but the stuff does a fine job.
