  • 3,000 Pulls, Under Load: How We Test the Part of a Bag That Fails First

    DONGGUAN, China — [Month Day], 2026 — Ask any bag factory where the warranty claims come from and you'll get the same answer, delivered with a sigh. Not the fabric. Not the seams. The zipper.It makes sense when you think about what a zipper is: the only part of a bag with dozens of moving components, operated several times a day, every day, usually with one impatient hand, often while the bag is stuffed past the point of reason. Everything else on a bag sits still. The zipper works for a living.So in our lab there's a machine whose entire job is to open and close zippers until something gives.
