I can't speak to SW's quality or anything b/c I don't own one, but I have seen a few up close. Please note... I'm NOT knocking them, just pointing something out. I REALLY DON'T think that his are Poly Viscose... I think SW's are either Poly acrylic or Poly Cotton (which would explain the pilling), but I'm not 100% sure since I don't have 1 in front of me to touch.

We've JUST (yesterday) received the "Ireland's National" tartan in Poly Viscose and it's better looking than it was in the swatches! It's not on the site yet, but will be in a few weeks. If you'd like to see a pic, email me and I'll send you one.

Keith... your kilt will go out Tuesday!

Hope this info was helpful, David.
