What soft, smooth fabric, usually made from cotton or a cotton blend, is primarily used for making pants?

Chino is the correct answer because it refers specifically to a type of fabric that is characterized by its soft, smooth texture and is primarily made from cotton or a cotton blend. Chino fabric is known for its durability and comfort, making it an ideal choice for creating stylish yet practical pants. The fabric typically has a twill weave, which contributes to its strength while maintaining a suitable level of softness.

While stretch twill is also a soft fabric that can be used for pants, it often includes added elastic fibers for stretch, making it different from the more traditional cotton composition and feel of chino. Broadcloth, on the other hand, is a finer fabric that is often lighter and more commonly used for shirts rather than pants. Ripstop fabric, typically associated with outdoor gear due to its strength and resistance to tearing, is not suited for everyday pants and lacks the smooth finish that would be expected in typical chino trousers.

Overall, the characteristics of chino fabric make it a preferred choice for comfortable and stylish pants, aligning perfectly with the specifics of the question.
