100% Mongolian Wool Set!! Country of Origin: Mongolia Made with high-quality Mongolian wool. Warm and extremely warm leg warmers. Made by Tod, a Mongolian company. In Mongolia, where temperatures can drop to -40 degrees Celsius, these leg warmers are worn layered inside boots. They are very warm and fit comfortably. They don't slip down even when worn up to the knee, making them warm when layered over tights with a long skirt. Recently, personal trainers and ballerinas have also been purchasing them. We purchase them directly from Mongolia.
