Planting a forest together; for every product purchased, a tree is planted.

Bamboo

Bamboo is still more of a sustainable option when compared to conventional cotton cultivation, as well as non-sustainable fabric manufacturing. (Especially when mechanically manufactured verses any sort of chemical process manufacturing.)  In any case, it remains to be the fastest growing plant that thrives naturally without the use of pesticides or fertilizers. It releases 35% more oxygen into the atmosphere than trees, and absorbs more carbon dioxide than plants.  Bamboo does not need to be replanted and can grow to maturity with just rain water; it needs very little water to grow. It has a short growth cycle compared to trees, and it can be a renewable resource for agroforestry production. Bamboo improves soil and helps control water pollution as well. 

Bamboo fabric is 100% biodegradable , incredibly soft, moisture-wicking, and has natural thermo-control.  It keeps bacteria at bay, and is good for all skin types.
