Mirror Lake Sleeping Bag: 22F Down - Women's

Shivering's crappy enough if you're inside and can take a bath to warm up, but it's ten times worse if you're outside with no prospect of getting feeling back in your toes 'til morning. Big Agnes spent a shivery night once, and had such a miserable time that it decided to design the Mirror Lake Women's 25-Degree Down Sleeping Bag with 600-fill water-repellent DownTek down to keep you warm during spring, summer, and fall camping trips and on winter hut trips. Not only is the down water-repellent, but it's laid out in vertical baffles that conform to your body for increased warmth and comfort, and the baffles have internal "gates" to keep all the insulation in place, preventing cold spots. The Pertex ripstop nylon shell's water-repellent as well, not to mention breathable.

Like all down, DownTek is valued for its high loft, light weight, and compressibility, which provides serious warmth at a light weight; in fact, the Mirror Lake weighs just about 2.5 pounds so it won't slow you down if you've got serious ground to cover. The mummy shape also offers a high warmth-to-weight ratio, especial if you factor in the drawstring hood, no-draft zipper, and collar that keep warmth in and unpleasant cold out. Big Agnes' left and right zippers mate together, too, so you can grab bags with opposite zips and make a doublewide, extra-roomy bag for two.
