HyperDRY™ Fluorocarbon Free Water Resistant Down Insulation


ALLIED Feather & Down's HyperDRY water resistant down is treated with a unique Fluorocarbon Free treatment that adheres to the down cluster that allows down to retain its superior warmth to weight ratio - even when wet. 


bluesign® approved  /  Responsible Down Standard certified  /  consumer traceable on trackmydown.com


The Achilles' heel of down is the fact that it is much less hydrophobic than other feathers on waterfowl. The down itself grows underneath these feathers and provides the birds with insulation - much like it is used in outerwear and bedding. With HyperDRY, the down itself becomes hydrophobic to help retain warmth even under the harshest conditions. 


What separates HyperDRY from other water resistant treated down in the market is the way it is processed. Using a proprietary process outside of a water bath, ALLIED is able to produce a high performing AND sustainable product - using significantly less water and energy, with a chemical adhesion of over 95% to ensure that no chemical is sent down the drain. 


When creating insulated products for the most extreme or luxurious environments, HyperDRY gives you the unparalleled warmth to weight of down, with the water repellancy of a petroleum based synthetic.
