The following is from Consumer Reports regarding "bamboo" sheets:Environmental claims were sometimes dubious. The Federal Trade Commission recently told 78 retailers, including Sears, whose rayon sheets we tested, to stop labeling and advertising rayon textiles as eco-friendly bamboo. Once the plant fiber is processed, it's rayon, not bamboo. Plus the processing uses toxic chemicals that emit hazardous air pollutants during manufacturing. Sheet sets we tested claim to be bamboo but should be labeled as rayon or a rayon/cotton blend.If you like this product- great. But do not be bamboozled that it is "green".
