How to

1. Confirm that your jacket has two sliders and that both sides separate at the bottom. Nonseparating two-slider zippers on bags may have different operation.
2. Move the upper slider fully down until it meets the lower one. Misaligned sliders can stop the insertion pin from seating correctly.
3. Feed the long separable pin through both aligned sliders all the way to the bottom. YKK warns that incomplete insertion can cause the zipper to malfunction.
4. Hold the jacket fabric steady near the hem and slowly raise the upper slider. Stop, lower it and check alignment if the teeth snag rather than pulling hard.
5. When sitting or moving, raise the lower slider slightly if the closed hem feels tight. Outdoor Research describes bottom-opening two-way zips as useful for ventilation and extra room.
6. To remove the jacket, lower the upper slider until it touches the lower one, then gently withdraw the pin. Seek repair if the pin or teeth are bent or damaged.

One more tip

These instructions are for separating two-way jacket zippers. A two-puller bag zipper may work differently. If the pin or teeth resist, never twist or force them; inspect the components first.
