This winter-ready bag has it all: 800-fill down for superior warmth and packability, strategically placed pods of synthetic Climashield Prism fill underneath that resist compression, and a HyVent waterproof/breathable shell that sheds the worst drips and indoor frost in condensation-stricken tents. "I used this bag in a wide range of conditions, from the soggy Columbia River Gorge to chilly Rocky Mountain National Park, and I have yet to find a flaw worth mentioning," says one tester. Another (warm-sleeping) tester crashed soundly on a 5°F night and was impressed by the conservative temperature rating.
The footbox is deep and spacious; the zipper runs buttery-smooth; a puffy neck yoke and draft tubes seal in heat like a toaster oven; and down doesn't shift to create cold spots. The three-pound weight is reasonable considering the performance, but you can save a few ounces by switching out the heavy compression sack for a lighter one. $369; 3 lbs. 1 oz.
