Moisture is no problem for our suppliers latest innovation in down processing. At the end of our suppliers proprietary multi-wash process, they add one ingenious step. A virtually weightless coating is applied and the result is a water resistant fill that retains all the qualities of the finest natural downs. Resist-Down™ is hydrophobic, engineered to keep you warm and dry for hours longer than untreated down. And if it does get wet, it dries up to three times faster than untreated down. All while retaining over 30% more loft than untreated down when exposed to moisture, and completely allergen free.
