Knickey makes all their underwear with certified organic cotton. They reduce and recycle water, both on the farm and in the factory. Yarns are woven and knitted into bolts of fabric, then dyed and finished with Oeko-Tex Certified Materials. Finally, fabric is cut and sewn into Knickey undies and shipped to NYC. Knickey also offers an underwear recycling program to make sure your used undies don't end up in the landfill.
