The softness of bamboo has been compared to the feeling of cashmere. It is highly sustainable because its vast, fast growing root system does not require replanting after harvesting. Its complicated root system is also beneficial in that it prevents soil erosion. There are two ways to produce this fabric, one is mechanically and the other is chemically. The mechanical way is far superior. Bamboo is broken down into mush using natural enzymes and then spun into fabric. The chemical way is much quicker but involves using toxic chemicals that have been linked to nerve damage. When checking labels make sure the product is environmentally friendly. Some reputable labels are Oeko-Tek, Soil Association, SKAL, KRAV or any brand that is certified organic and sustainable.
