What Eco-Friendly Fabrics Should You Search For?
The top fabric for eco-friendly underwear is organic cotton, but you can also find great styles in Tencel, Modal, Hemp, Silk, Recycled Polys and Bamboo. Each of these fabrics has their unique characteristics and create a different feel. If you prefer ultra-soft, Tencel and Bamboo might be a good fit. If you need more of a performance pair, go for recycled polyester. Whatever you pick from this list, you are choosing a much more sustainable product than what you find in conventional stores.
