Restore the durable water repellency (DWR) of the waterproof/breathable fabrics on your 509 outerwear and gloves with the Nikwax TX.Direct® Wash-In treatment. Over time, technical fabrics, including GORE-TEX, get dirty and lose waterproof performance. Nikwax TX.Direct® completely restores surface water-repellency and enhances breathability. Nikwax TX.Direct lasts several washings and does not need to be reapplied after every wash like other treatments.
