Familiarity: I've put it through the wringer
I bought this bag not knowing what to expect on a 12 day trip from LA to Washington's peninsula in mid-May, meanwhile going through all the National Parks in between. I've used it with an ENO hammock and underquilt, a backpacking tent and inside the driver seat of my sedan. It's great at keeping me toasty without the sweat- in snow, in rain, overnight sleeping while sitting in a closed car, in cold north-american weather. I have no doubt that it'll be perfect for Alaskan climate as well! Waterproof and easy to take care of. Packable feature is a plus too, definitely will bring on a cold backpacking trip!
