Depending on how old your jacket is — and how often you use it — you may need to restore the water repellent treatment on the outside of the fabric. Luckily, there's an easy fix.
Kathmandu Product Expert Daan Dijkstra explains the best way to restore your waterproof garments.
In a nutshell, to stay dry! DWR can diminish in performance due to a number of factors — like dirt, sweat, abrasion and constant use. Usually the DWR treatment will encourage water to bead up and roll off the surface of your garments. But as the treatment begins to fade, the fabric will start to absorb water instead.
After washing your waterproof jacket, use a specialised product like Granger’s Performance Repel. Spray directly on the damp garment from a distance of 4–6 inches.
Wait for two minutes, and wipe away any excess with a clean cloth.
