ExpeDRY

ExpeDRY is the new chemical free alternative to water repellent treated hydrophobic down. Using gold particles (from recycled electronic equipment), that are permanently bonded to the down clusters, it is completely non-toxic and will never wash out. A chemical free alternative to other methods of treating down to make it hydrophobic. Applied without heat using the Van der Waals interaction, reducing energy used in production by 30%. Aiding evaporation of water molecules to resist humidity. Allowing the down to dry 40-50% faster in consumer washing versus non treated down.
