Time to wash your down jacket? What about your down vest or down sleeping bag? Down performs best and functions properly when it is clean and dry. As anyone with a down jacket knows, once the down fill gets wet and damp, it loses most of its insulation properties and becomes useless. But when down is dry, it is one of the best insulating methods out there, able to keep you warm in the coldest conditions. Care for your down, and it will care for you. | Nikwax Outdoor Innovation
