I've got quite expensive ski jacket with 4 YKK zippers.

3 of 4 zippers are broken after few years of usage.

This is a little late for your nice jacket, but a lot of zipper damage comes from dirt getting into the teeth and then the zip grinds everything up. Outdoors shops sell a zipper lubricant to keep the dirt from sticking.

I have multiple ski jackets and ski a couple times a week. No broken YKK zippers.

Do you know a better zipper?
