850 Down Sleeping Bag 19 F/ 7 C Short

45 years ago, discouraged with the performance of existing sleeping bags, Yvon Chouinard built a mummy style bag with overstuffed channels and a center front zipper so he could tie in at belays, cook at bivies, move around without the bag twisting, and have consistent loft trip upon trip. Inspired, we set out to create our own version of Yvon's innovative bag. The result is the new 850 Down Sleeping Bag an elegant, real world bag, built with the best materials available and 45 years of down construction expertise. We started with ultralight 100% nylon ripstop Pertex QuantumR fabric, which 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 HoudiniR fabric a featherweight 100% nylon ripstop that provides quick dry times and soft, next to skin comfort. We insulated the bag with 850 fill power Traceable Down for exceptional heat trapping warmth, season after season durability, ultracompressibility, 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.
