Chino cloth
Chino cloth (/ˈtʃiːnoʊ/ CHEE-noh) is a twill fabric originally made from pure cotton. The most common items made from it, trousers, are widely called chinos. Today it is also found in cotton-synthetic blends.
Developed in the mid-19th century for British and French military uniforms, it has since migrated into civilian wear. Trousers of such a fabric gained popularity in the U.S. when Spanish–American War veterans returned from the Philippines with their twill military trousers.
