Allied Feather + Down launches ExpeDRY, the first chemical-free, fast-drying down insulation

To create ExpeDRY, the world’s fastest drying down, ALLIED is partnering with FUZE Biotech, makers of safe, sustainable, and chemical-free textile enhancements.

In keeping with its commitment to performance and sustainability, ALLIED Feather + Down -- the world’s leading supplier of ethically sourced down -- is proud to introduce ExpeDRY quick drying down, featuring FUZE technology.

Available to all ALLIED partner brands, ExpeDRY is a chemical-free solution that keeps the performance that down is renowned for, and makes caring for down products easier, while reducing energy consumption and broadening down’s performance range.

ExpeDRY helps reduce dry times while minimizing performance issues in wet weather by using non-ionic, permanently bonded gold nanoparticles to the down cluster. These particles work to increase the evaporation rate of water at a molecular level, without the need for heat.

This technology differs from current water resistant treatments for down. The common DWR treatments act as a hydrophobic agent which allows water to bead, keeping the down clusters drier for longer. However, once saturated, DWR treatments have no ability to accelerate drying. In real world situations, the increased evaporation rate created by ExpeDRY could actually be of greater benefit than many DWR treatments. And once saturated through a thorough cleaning, ExpeDRY-treated garments will dry almost twice as fast.

ExpeDRY has been tested to dry 40 to 60 percent faster than untreated down, making it significantly easier and faster to fully dry a jacket in traditional and condenser dryers. It also helps down products air dry faster between uses in wet environments.

This project has been at the top of our priorities and in development for years,” said Daniel Uretsky, President of Los Angeles-based Allied Feather + Down. “Not because it might help someone summit an 8000-meter peak faster, but because it will make down more accessible to more people.”

“We almost thought the project impossible until our partnership with Fuze,” continued Uretsky. “Using their incredibly knowledgeable and unique approach to innovation and dedication to sustainability, we are finally able to realize our quick-drying product. This is a potential game changer for the European market that relies on condenser dryers, which have always made down difficult to care for and dry properly.

Andrew Peterson, Chief Technology Officer of FUZE Biotech, said, “Working with ALLIED on long-term sustainability goals and other exciting product developments allowed us to come across an interesting new area of study where we find that gold nanoparticles significantly increase the evaporation rate of water. This technology has exciting implications that extend far beyond the apparel industry.”

In long-term exposure in wet climates, ALLIED has found that the loss of warmth is primarily due to extreme levels of humidity as opposed to direct contact with water. The gold nanoparticle technology employed by ExpeDRY creates an electro-static barrier that increases hydrophobicity as well as interacting with water’s hydrogen bonds. This combination keeps the humidity from forming water droplets and helps to break them up, facilitating faster drying when water is present. In virtually every real-world scenario ALLIED has tested, ExpeDRY performs as well or better than the leading hydrophobic water resistant down currently available. Made with gold from recycled sources, ExpeDRY is chemical free and uses approximately 70% fewer resources than water resistant down.

“What started as a project to help make down easier to care for has turned into what we consider is quite possibly the best insulation on and for the planet,” added Uretsky.
