Compressible, lightweight warmth. Featuring water-repellent, hydrophobic goose down, developed by Downtek™, and sophisticated hybrid constructions, our 850 Fill Power down jackets maintain loft and insulation irrespective of conditions. Downtek™ hydrophobic down stays dry 10x longer than untreated down. Unlike inferior versions, our water repellency does not wash out. Responsibly engineered, we use only Downtek™ ZeroPFC™, a fluorocarbon free, natural lipid water repellent treatment. This is applied using a vapour process, instead of a bath process, further reducing the possibility of harming water systems. Ethically sourced, 100% of our down is Responsible Down Standard Certified.
