Ouray Sleeping Bag: 0F Down - Women's

Shiver is a nasty six-letter word that the Marmot Ouray Women's 0-Degree Sleeping Bag wouldn't recognize; this super-warm and lightweight bag just crushes the cold of winter without breaking a sweat. Rather than simply renaming a men's sleeping bag and tossing it out there, Marmot's engineers added down insulation right where testers said they felt the coldest, and gave the Ouray a trapezoidal footbox to heat your toes more efficiently. It also has an insulated five-baffle hood, down collar, face muff that seal up tight so your brain doesn't freeze during the frigid mountain nights.

That's not the end of it. The Ouray also uses stretchy baffles that let you move around comfortably, and has a trapezoidal footbox that's designed to keep your toes extra-warm when temps are extra-cold. An insulted draft tube prevents cold air from sneaking in through the zipper, and ground-level side seams help prevent all your hard-earned warm air from sneaking out. There's a little stash pocket, too, so you can keep your essential whatnots and thingamajigs close by, and two-way locking zippers so you don't come undone in the middle of the night and wake up hypothermic.
