A backpacking truth: You can say what you want about the details of a bag’s construction, but the real measure of its value comes on nights when you need it to accomplish just one function—keep you warm. Beside Quiet Lake at over 9,200 feet in Idaho’s White Cloud Mountains in early October, I awoke to find frost coating much of our gear that we’d left outside the tent; the overnight low had dropped nearly to freezing. And I had not even noticed the cold, snoozing comfortably all night in the Scandium.
