Patagonia has successfully built the finest down parka ever made. The Encapsil™ Down Belay Parka is 100% independently baffled and differentially cut, and insulated with Patagonia’s Encapsil™ down – a proprietary, plasma-treated, water-repellent down with an unprecedented fill-power of 1000. Sadly, this jacket is completely sold out. However, rumor has it that Patagonia’s Encapsil partner, AeonClad Coatings, is already working on a 1200-fill power treatment.
