Chosen Solution

I have a worn slider on a Patagonia winter jacket zipper. I’m not sure of the product name - it’s a recycled women’s hooded winter jacket (brown), purchased around 2010 from a retailer. How do I request the specific zipper slider and zipper stop to make this repair myself? Thank you!

Take it to a good haberdashers shop and see what they suggest. But if you can possibly replace the entire zip you’ll probably do much better than trying to keep a worn one alive.
