Just to note, current Harris tweed offerings seem to be back on track with many different choices than just 4. There are three main companies offering Harris tweed, largest to smallest: Harris Tweed Hebrides, Harris Tweed Scotland (Haggas-owned), and the Carloway Mill. As with most things, it pays to look for the best quality and most ethical suppliers.
