Texas Jean Company, Wrangler, American Clothing, some Carhartt, Woolrich, Filson, etc...
Go back to the beginning of this thread and I listed numerous sites where you can buy US made clothing, shoes, socks, jackets, etc.. Go to the company web site and search on US made and most will have a small portion of their clothes still made in the US.
Levis is a sad disappointment...and their quality of late just sucks!
T-Shirts are not hard to find made in the US. Just have to do your homework.
