Chinos are an immensely popular type of casual pants made from chino fabric. The fabric is a twill weave of all cotton or a cotton/polyester blend. Durable, closely woven and lightweight, chino fabric was originally used for warm-weather army uniforms. "Chinos" is often used interchangeably with "khakis," as the original chinos were often khaki-colored. Modern chinos wash and wear well, with minimal care required, come in several different colors and are the uniform of many.
