WHY BAMBOO & ORGANIC COTTON? Bamboo is the fastest growing plant in the world and doesn't need insecticides, pesticides, or a complex watering system to grow. It just needs sunlight and rainwater, which it turns into a whole bunch of oxygen - much more than your average tree. And organic cotton is grown using old-school techniques and methods. There are no herbicides or any other chemicals used in the growth of organic cotton, and it's normally rain-fed.
