A used rain jacket that lets water soak through isn't broken - it just needs a reset. If you picked up a used columbia or any other shell jacket, the DWR (durable water repellent) finish is probably worn out. The good news is that with the right wash and a quick reproof, most jackets can bead water like new. Here's exactly how to do it. What Actually Makes a Rain Jacket Stop Working?

DWR is a chemical treatment applied to the outer shell during manufacturing, and it breaks down with sweat, dirt, skin oils, and regular washing. When it degrades, water no longer beads and rolls off - it soaks into the fabric instead, a process called "wetting out." This makes the jacket feel heavy and cold, even though the inner membrane may still be fully intact. A 2019 study published in Environmental Science & Technology found that most DWR coatings are fluoropolymer-based and...
