Recycled Polyester - There are over 5.25 trillion pieces of plastic debris floating in the oceans. Recycled polyester won't fix that but this is better for the Earth than creating virgin polyester for products.
Recycled Wool - Worn out wool goes through a meticulous sorting of materials into color categories prior to rebirth so the dyeing process can be completely eliminated to save water and chemicals as well as eliminating the resulting wastewater.
