It’s not the GORE-TEX that’s stopped working, it’s the DWR coating. Non-Gore options rely heavily on a DWR coating which forces water to bead off the garment. GORE-TEX fabrics utilize the same DWR coating which works hand in hand with the GORE-TEX membrane for superior water repelling. Heavy use of any garment coated with DWR will eventually need to be refreshed. It may seem counterintuitive to machine wash & dry your GORE-TEX outerwear to revive the DWR coating, but it’s not! The coating actually relies on the heat of the dryer to realign the microscopic pegs that repel water. Keep reading for GORE-TEX care instructions. If washing & drying fails to reinvigorate the coating, you can use a spray or wash-in product to achieve a like new water repelling result.
