While the bamboo itself is a great organic and sustainable source of fiber for clothing and linens, the process to get it that way isn't so "natural". When I was selling wicking sleepwear, the manufacturer I worked with would not sell jammies made with bamboo because of the chemical process it has to go through to get there.
Here's a link with some info on the different ways bamboo is processed into your towels, linens and clothing:

My kids and husband tease me about it, but I firmly believe that many of our health issues, and even other problems like autism and severe allergies, are related to all the chemical additives in our foods, our cookware, our plastics, our clothing, and even the very air we breathe.
I just don't know how you can escape it all, unless we join a nudist colony on a warm beach somewhere - - but then we'll have the oil spills to deal with!
