After scouring the market, we can confirm that SD's claim is true: this is the lightest 15ºF bag you can get. How'd designers do it? First, they used premium 850-fill down and a wispy 15-denier nylon shell. Then they took a ruthless approach to trimming excess weight, eliminating any feature not directly tied to warmth. They shorted the zipper to 25 inches (it's hip-high) and pinched overall dimensions by about 10 percent compared to SD's other 15º bags.
