Are EcoSox really made out of Bamboo?
Absolutely. Bamboo is a grass, and although the outer wall is hard, the leaves and inner pith can be made into pulp by crushing and mixing them with caustic soda, a low impact chemical. It’s then spun into bamboo fiber that’s no thicker than the average human hair. It has a round smooth surface perfect for spinning into bamboo yarn and then eventually knit into socks.
