Chinos are made of a twilled cotton fabric originally used for uniforms, work and sports clothes. The term chino is now used to loosely describe any cotton twill pant and is usually synonymous with the term khakis. The word comes from the Spanish word for China. After the Spanish American War, American troops were stationed in the Philippines where many natives spoke Spanish and used the word chinos to describe pants imported from China. The pants’ popularity rose when soldiers returned home and wore them in college classrooms.
