the full article from the FTC website:

i've never bought the stuff and hadn't planned to. too expensive altogether.
having read the whole FTC article, i can't help but wonder how the bamboo plants are processed before the stuff gets to the Kyoto plant for final manufacture of the battting. i can't find any detailed description of the entire process, from grove to batting plant, that proves anything either way.
i believe people should feel free to buy what they want, so i'm not trying to change anybody's mind. but the old adage, "buyer beware" still applies.
