Yes, a difficult search. . The biggest issue with them is that it is very hard to find in 100% natural fiber. As a result of this difficult search, I'm no longer entirely opposed to blends if it is not a suit, but many blends end up lookingcheap, some are cheap, some aren't, but I don't want them to look that way.
I'm on the road, so I can't check what brands I have now, but to move towards synthetic fibers, you usually need to go down market to Macy's or even penny's or something like that. I find 50-75% of them look bad, but the decent ones end up being very easy to are for.
I do have the jos a bank in a herringbone in wool, so there's one pair.
