Shahtoosh
Shahtoosh (from Persian شاهتوش 'king of wools'), also known as Shatoush, is a wool obtained from the fur of the chiru (Pantholops hodgsonii, also called Tibetan antelope). Also, shawls made from the wool of the chiru are called shahtoosh. Shahtoosh is the finest animal wool, followed by vicuña wool. As undomesticated wild animals, the chirus cannot be shorn, so they are killed for this purpose. Due to the severe decline of the chiru population by 90% in the second half of the 20th century, they were internationally classified as a critically endangered species until 2016.
