Nikwax Down Wash Direct (1 litre) Nikwax, the global leader in outdoor aftercare, is excited to introduce Down Wash Direct, the first aftercare product specifically designed to clean and maximise the performance of both regular untreated down and treated hydrophobic down. Down is a highly effective insulator, but quickly loses its insulation powers when saturated with water. Water-resistant down fills, such as Nikwax Hydrophobic Down (NHD) technology, address this issue. Nikwax has developed the innovative Down Wash Direct to serve the expanding offering of treated, water-resistant down products. With repeated use, dirt, oil, and other contaminants diminish the water-repellency of treated down and so to restore performance it requires special care. Down Wash Direct ensures optimal results by cleaning effectively, revitalising insulation, and restoring the water-repellency of hydrophobic down clothing and sleeping bags. It also improves the water-repellency of regular down, with tests revealing untreated down absorbs almost 40 times less water after just one wash in Down Wash Direct. Additionally, it ensures the water-repellency of the down item's outer fabric is maintained or even improved. Like all Nikwax products, Down Wash Direct is PFC-free and water-based for the lowest environmental impact. In addition, Nikwax only works with down processors that are committed to ethical sourcing.
