Hi Atticus,

I have a kilt made of each of the materials, actually, one is a wool blend. Personally, I like to poly vis.

I like it for durability and toughness, it's coated with teflon so marks such as coffee stains or spills wipe off easily.
It's easy to care for.

Sure it's not in the same league for quality as pure Scottish wool, but it's a great substitute.

Have you read through the info about which kilt is right for you?
