FWIW, that's often a good thing with Panama hats. Don't know where Borsos are exactly made, but the best Panamas come from Ecuador. Cheap ones are from China.

Yes if they're not made in Ecuador they're not really true Panama. The best are generally made in Montecristo with cheaper hats made in the Cuenca area.
Optimo in Chicago sell high quality Montecristo made Panama's, but you're talking $500 for a cheap one up to thousands of dollars for the finest weaves.
Personally I'm happy with cheap Cuencas. Some shops grade their hats by the weave count, but no two shops use the same grading system...
