DWR treatment to wear out over time. When the factory applied treatment can no longer be reactivated, apply a new water-repellent treatment (available from your local retailer) to the garment’s outer fabric. We normally advice to use spray-on treatment after washing and allowing the garment to drip-dry. After spraying the treatment, only on the outside of the garment, tumble dry on a low warm setting for 10-15 minutes. Tumble drying will help reactivate the DWR treatment on your garment’s outer fabric
