Restore water beading on a waterproof shell jacket
Loss of surface beading does not always mean the waterproof membrane has failed. Check cleaning and DWR instructions first.
A waterproof shell may have a durable water repellent (DWR) finish that encourages droplets to roll off its face fabric. GORE-TEX explains that reduced beading is not automatically membrane failure. Many standard garments can recover beading after proper washing and manufacturer-approved gentle heat, but special fabrics such as SHAKEDRY must not be tumble-dried, ironed or reproofed. Read the garment label first.
