Big Agnes Mystic SL Sleeping Bag: 15 Degree Down -

Strap your feedbag on and chow down on some serious sleep in the Big Agnes Mystic SL 15-Degree Down Sleeping Bag. It has plenty of warmth for three-season trips, and will also crush winter hut or yurt trips. The Mystic ditches bottom insulation in favor of an integrated sleeve into which you slide a compatible sleeping pad, cutting down on weight and actually boosting warmth. As a result, the Mystic weighs less than 2.5 pounds. Don't think for a second that it sacrifices warmth, though; it's loaded up with 800-fill DownTek water-repellent down that's arranged in Insotect Flow vertical baffles. The baffles conform to your body for increased warmth and comfort and use internal gates to keep the down in place so you don't have to deal with cold spots.

Not only is the down water-repellent, but the Pertex ripstop nylon fabric is so tightly woven that it prevents moisture, like tent condensation, from seeping in. The rectangular shape means you have sleep-position options. Drafts tremble in fear before the Mystic, too—they're scared of the no-draft collar, wedge, and zipper that keep them locked out and your heat locked in. And, as a final touch, Big Agnes designed the Mystic so that left-zip bags can connect to right-zip options, letting you and all your stuffed animals sleep together comfortably.
