I currently have a 13oz "8 yard" wool kilt, a "tank" as I heard Jimmy call them. Not too sure if it is an 8 yard since I do have a 50inch waist, probably a 9 or 10 yard. I am seriously thinking of ordering a USAKilt Traditional, the one that is a step above the philabeg. I believe the Traditional are poly-viscose. How does USAKilt poly-viscose behave in relation to a 13oz 8 yard wool? Would I see much difference in the appearance, movement, hang, and sway? Thanks for helping a potential USAKilt customer.
