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. Additionally, zippers allow for easy access and tend to be more efficient than other closure options like buttons or snaps.
Zippers can be prone to malfunction, such as getting stuck or breaking, which can render a garment or bag unusable. They may also snag on fabric or hair, causing damage or discomfort. Additionally, zippers can be less flexible than buttons or snaps, limiting design options and ease of use in certain applications. Finally, they can add bulk to the design, which may not be desirable in some clothing or accessories.
