My understanding with talking with Jason is the fabric they used by Toray was made in Japan. If you remember the tsunami, earthquake and nuclear meltdown put there orders numerous months behind as the Toray factory wasn't that far from the affected areas and their materials production and exporting of it slowed down substantially.
I am all for Made in USA, but to think everything I own or use is made here would be impractical. As much as possible, surely, but everything not even close.
In today's business, how to American companies compete with labor rates overseas, they don't and can't. If an American made company is the one of the Top Dogs in their market area they can do it, if not, profits drive where they go for labor and that is usually overseas to some 13 year old working in a factory. Not what we would choose, but reality.
