Chinos are trousers made from chino cloth, which is a twill fabric originally made from pure cotton. The fabric is known for being lightweight, durable, and breathable, with a distinctive twill weave. Historically, chinos were developed in the mid-19th century as part of British and French military uniforms, and later popularized in the U.S. by veterans returning from the Spanish-American War, where soldiers obtained these durable cotton twill trousers from China—hence the name "chinos," derived from the Spanish word for China. Chino pants are typically made in a flat front design without pleats and often come in khaki or similar earth-tone colors, although they are now available in a wide range of colors. They are considered more smart-casual compared to jeans and more versatile than formal trousers, making them a popular choice for occasions that require a neat but not overly formal look. Key features of chinos include:

• Made from lightweight twill cotton or cotton blends
• Flat front with no pleats
• Tapered or straight legs
• Usually have five pockets (two front, two back, and a small ticket pocket)
• Zipper fly and button closure

Chino pants are less heavy and more breathable than traditional khakis, which are typically made from heavier cotton and have visible seams and more prominent pocket designs. Chinos are more fitted and can be styled for semi- formal wear, suitable for work, social events, and casual outings. In summary, chinos are versatile, durable cotton twill pants originally designed for military use that have become a popular smart-casual wardrobe staple.
