Home Waterproofing Sweatproofing Eco Materials Directional Textiles Blog English Chosen by global outdoor brands Nikwax Eco Materials has developed the world’s best performing hydrophobic down, keeping explorers warmer and drier in extreme and cold conditions, without the use of harmful fluorocarbon (PFC) chemistry. Nikwax enhances the performance of nature’s best insulator (down), to create the lightest, most efficient, water resistant down. Nikwax Hydrophobic Down + goes one step beyond by being the first and only hydrophobic down to exceed 10,000 minutes of continuous shake time in the IDFB 18a industry standard shake test, equating to 7 days of constant aggressive exposure to water. We are proud that partners such as Haglöfs, Therm-a-Rest and Nomad use NHD+ technology to treat their down filled products, increasing the range and extremity of conditions they can be used in.
