The Irish County tartans are owned by House of Edgar and the Irish County CREST tartans are owned by Gaelic Themes (and WOVEN by Marton Mills).

The material is only woven in wool... they WILL NOT weave it in anything OTHER than wool and since they own the tartans (think of it as a copyright), it's their decision. Therefore, you'll only find the Irish County tartans in "expensive" wool kilts.

Depending on your definition of "expensive", you can get a less expensive one... for instance, we offer a 5 yard wool kilt at $350 - $375 (for any of the Irish County Tartans). If you're looking in the $100 range, you won't find anything.

As Panache mentioned... the best alternative is the Irish National or Ireland's National or Saffron
