Sprinkle some water on the outer fabric. If it beads up and rolls off, the DWR is still effective. If the water soaks into the fabric and creates a dark, wet patch (called 'wetting out'), the DWR has degraded and needs reapplication. Wetting out doesn't mean the pants leak—water still can't penetrate the waterproof membrane—but it dramatically reduces breathability because the wet outer fabric blocks moisture vapor escape. Reapply DWR treatment using products like Nikwax TX.Direct after cleaning the garment.
