I go to school in Eastern Washington and have been desperate to find a warm jacket. I was looking for a good all around down jacket that would keep me warm in the fall and winter, without being too hard core (extremely high fill)--I found it. The 550 fill has been perfect for cold nights (in the low 30s) and even during the day when it gets about 50. In class, it is comfortable to leave on (I don't get too warm). The only way you notice it's cold outside is by the feeling of the parts of your body not protected by this beast of a jacket.
I don't have any experience yet with it in truly cold weather, but so far it's been perfect.
I wouldn't recommend it for rain, however--they nylon shell will allow the down to get drenched. Besides, there's no hood on this bad boy.
It's got a sweet look to it, too. Be prepared for countless compliments.
Highs: Perfect fill, good build, looks great, killer price
Lows: Might be too light for frigid weather, not meant for rainy days (that's what a rain jacket is for, anyway)
