With its zipperless design and integrated comforter in the bag’s upper half, the Sierra Designs Cloud 35 bag achieves the strengths of mummies and quilts without their weaknesses.

The forecast made me sit up and wonder: Will my bag be warm enough? For the three nights in late December that I planned to spend in a tent in Idaho’s Boise Mountains, lows would drop into the teens and single digits Fahrenheit—slipping below the “comfort” rating and approaching the “limit” rating of my Mountain Hardwear Phantom 0. And this on my maiden voyage with the bag; I had not used it yet. As it turned out, I had nothing to worry about with this extraordinarily warm and packable, ultralight winter sleeping bag.
