ALLIED Feather + Down’s ExpeDRY™ Ultra Dry Down Secures Okeo-Tex® Standard 100 Certification and bluesign® Approval (10/16/25)

ALLIED Feather + Down, global leaders in high performance, responsibly sourced, and sustainably processed down, recently secured Okeo-Tex® Standard 100 Certification and bluesign® approval for their ExpeDRY Ultra Dry Down insulation. Designed to outperform current chemistry-intensive hydrophobic down treatments and approved for safe use by the textile sustainability authorities at Okeo-Tex and bluesign, ExpeDRY is both cleaner and better performing than standard down treatments in real world situations. “As material innovation evolves and incorporates new solutions, globally recognized certifications play an increasingly important role in supporting sustainability claims and building trust with product developers and brands,” said Daniel Uretsky, President of ALLIED Feather + Down. “The Okeo-Tex Standard 100 certification and bluesign approval bring credibility to what we already know: ExpeDRY takes down, which is arguably the lowest impact insulation on the market, and elevates it to the highest performing insulation, all with less impact on the material than traditional hydrophobic chemistry.” ExpeDRY is the result of years of research into how down and moisture interact inside of an insulation chamber. After bringing the world’s first hydrophobic down insulation to market, ALLIED learned that these traditional chemistries not only introduce PFAS and other questionable chemistries into the environment, but also lack performance as they tend to slow evaporation and retain moisture inside jackets and sleeping bags. While the down itself stays dry, water droplets can become trapped inside the insulation chamber, slowing dry times and compromising warmth. ExpeDRY uses FUZE Technologies’s unique gold micro particles to actively reduce moisture in the entire insulation chamber by slowing the formation of water droplets and speeding evaporation. Gold itself is inert, and with FUZE’s ability to control the size and shape of the particles, there is no concern over nano or cytotoxicity. And due to the minute size of the gold material, the amount needed in a common down jacket equates to roughly two grains of salt. Because of this, ALLIED is able to secure Oeko-Tex standard 100 certification and bluesign approval. “For decades, there has been a fear of using metals to enhance performance, but this is all based on toxic, outdated, silver, zinc or copper ion release technology,” said Andrew Peterson, CTO of FUZE. “FUZE’s parent company is heavily involved in the biomedical space and its proprietary gold meta material technology aids in targeted pharmaceutical therapeutics and medical device development. By using this pharmaceutical grade material, ExpeDRY addresses all environmental and safety concerns, and we are glad to see the certifications backing this technology.” ExpeDRY has been adopted worldwide by ALLIED partner brands and demand has quickly overtaken ALLIED’s own hydrophobic down treatment. Now, brands will have even more reason to adopt it.
