For the three nights in early winter, as temperatures slipped into the teens and single digits Fahrenheit outside my tent on the snow in Idaho’s Boise Mountains, I zipped up snugly inside my sleeping bag and lay on this fat, well-insulated air mattress, briefly considering that I might feel cold before morning. And every morning, I awoke after sleeping longer and later than I normally do in my bed at home, feeling incredibly well rested and realizing my bag and air mat could have handled even colder temps.
