Yup, and that is why I showed you how to determine the weight of fabric for your self.
Any site that offers a 16oz synthetic fabric should be viewed with a critical eye. As of today, there is no 16oz synthetic kilt fabrics anywhere in the world.
These kilts are made in Pakistan. The city of Sailkot to be exact. Most people do not know that Saikot, Pakistan is the largest producer of kilts and other Highland style wear in the world.
But as the Pakistani's are not familiar with Scottish culture or heritage you would expect some misunderstandings. They see other sites advertise kilt fabric as being 16oz as the standard for highest quality. So they do the same. It is a similar thing to the use of P/V. There are sites that advertise P/V kilts with pride. Without fully understanding what P/V means the Pakistani's adopted the phrase and applied it to almost any synthetic fabric.
