Patagonia 850 Down Sleeping Bag 19°F / -7°C - Regular

The 850 Down Sleeping Bag is a real-world bag built with the best materials available and 45 years of down-construction expertise. We started with ultralight 100% nylon ripstop Pertex Quantum® fabric, which is windproof, down-proof and features Y-shaped filament technology to create a shell that’s nearly half the weight and twice the strength of our other down shell fabrics. The interlocking Y-shaped fibers of this fabric allow maximum down loft, provide superior durability and enhance the performance of the DWR (durable water repellent) finish. We made the liner from our beloved Houdini fabric—a down-proof, featherweight 100% nylon ripstop that provides quick dry times and soft, next-to-skin comfort. We insulated the bag with 850-fill-power Advanced Global Traceable Down (goose down certified by NSF International from parent farm to apparel factory to help ensure the birds that supply it are not force-fed or live-plucked) for exceptional heat-trapping warmth, season after season durability, ultra-compressibility and light weight. Built with a state-of-the-art differential baffle construction, we’ve eliminated sewn-through seams to banish cold spots and make sure the down stays lofted regardless of your sleep position. Our low-profile hood is designed to move with you and minimize twisting; it fits securely around your shoulders and head with lightweight cording and concealed cord locks. The custom foot box has a fully baffled, differentially cut pattern to eliminate any dead spaces, maximize warmth and allow ample room for movement.
