Zippers are used on jeans because they are durable, reliable, and convenient for opening and closing the pants. They provide a secure fastening method that can withstand frequent use and movement associated with wearing jeans.

Zippers are typically made out of metal, plastic, or coil teeth attached to a fabric tape. The teeth interlock to close the zipper and create a secure fastening mechanism for clothing, bags, and other items.
