Bamboo/Cotton 2 pack crew
This two-pair pack comes black or white, made from primarily bamboo yarn. Bamboo is a soft and porous fiber which makes it breathable and excellent wicker of moisture. Bamboo is naturally sustainable as opposed to cotton, bamboo uses virtually no pesticides or fertilizers and still grows at a rate of 36 inches per day. If reducing your carbon footprint is important to you will be happy to know that bamboo absorbs 35% more carbon dioxide than a typical oak tree.
