I am looking for a kilt jacket and I as I browse I see a lot of tweed, Harris tweed, and the like. These are made in Scotland and usually priced at around $300-$350 US. Now, I have also seen kilt jackets in the usual cuts of Argyll, Crail, and such but they are advertised as 100% wool. These are also made in Scotland, but they are priced at $175-$200.

So my question for the rabble is, what makes tweed superior to regular wool when making kilt jackets? Why is tweed priced higher? Thanks in advance for the info!
