The YKK Coil zipper is the industry standard for strength and flexibility. Engineered with a continuous nylon monofilament coil, this zipper easily navigates tight curves and bends while providing exceptional lateral strength. It is highly resistant to impact and self-heals easily if the teeth are forced apart.

Designed with a robust #5 profile and a standard open-end separating configuration, it allows garments to fully open while providing reliable, flexible performance. It is the premier choice for front closures on hoodies, fleece jackets, activewear, and everyday mid-weight outerwear.
