45 years in the making, the Patagonia 850 Down Sleeping Bag is inspired by the bag that brand founder Yvon Chouinard built for himself decades ago, featuring a simple mummy-style silhouette with overstuffed channels and a center-front zipper. The bag is built for three-season efficiency and is available in 19°F / -7°C and 30°F / -1°C models, both of which are EN tested and rated. Each features a differentially cut foot-box pattern that eliminates dead space and bulk, while the insulation is made up of ethically harvested 850-fill-power Traceable Down, good for exceptional heat-trapping warmth and maximum. The exterior is ultralight 100% nylon ripstop Pertex Quantum fabric, treated with a DWR (durable water repellent) finish, and the liner is made from quick-drying 15-denier 100% nylon ripstop, the same featherweight fabric found on Patagonia’s beloved Houdini styles. The Down Sleeping Bag is available now in short, regular and long sizes.
