Wranglers are 90+ percent manufactured in Mexico. There's only one production plant in the because the Professional Bull Riders Association (Wrangler's a huge sponsor) requires a US presence.
There's only one jeans brand completely made in the USA. It's based in Texas, I think.
That's one plant in the United States.
Doesn't rain on my parade at all. The math is the same, pick any product with with more than one company in America and at least one not in America, it all works out the same, the "buy American to protect a job" method only works if the American company in question is a monopoly... and then they probably can stand to lose a couple of sales.
