Patagonia
Patagonia and iFixit are celebrating the stories we wear by collaborating to provide guides for Patagonia's most popular apparel repairs.
Introduction
Go to step 1 ↓A cord lock is a small mechanism, often made of plastic, that is attached to a drawcord to secure it in place, allowing for easy adjustment of tightness and looseness. When the cord lock is damaged or missing, the drawcord becomes non-adjustable.
This guide demonstrates how to replace a cord lock without the need for sewing. To ensure this solution is applicable, confirm that the cord lock is not sewn in place and that at least one end of the drawcord is not sewn into the item, allowing for the cord lock to be removed without undoing any stitches.
Read through the entire guide before starting the repair, and gather the necessary tools and materials. While Patagonia-specific materials are ideal, they are not required. Patagonia replacement parts can be obtained by calling or messaging Patagonia Customer Service.
Alternatively, Patagonia products can be taken to a local retail store for repair evaluation or sent in to Patagonia through their mail-in repair service.
Let's get fixing!
WARNING! Small Parts. Patagonia does not recommend conducting these repairs on garments intended for children age 3 or under. Instead, we recommend return of the product for professional repair services.

VARIATONS: There are many varieties of cord locks on the vast array of Patagonia items. The techniques and steps outlined in this tutorial can be rearranged or modified to fit the circumstances.
-
MISSING CORD LOCK: If the cord lock is missing entirely, use the remaining cord locks and grosgrain loops as context clues. Alternatively, try to find photos of the item on Patagonia.com, WornWear.com, or Google image search.
