I absolutely love this jacket. Love the color, the fit is spot on, these jackets are more slim fitting than others. First thing you notice when putting it on, is it weighs NOTHING. that's the biggest thing about it. You think, there's no way this thing can keep me warm. Well, I wore only a tank top underneath, and was completely comfortable and warm in 45 deg temps.

Something interesting to note:
I purchased two of these Mountain HardWear jackets the same time. One from Amazon, and One from MooseJaw.com.

The one from MooseJaw just seems Nicer. Not by much, very subtle differences. I dunno if it's in my head. But the one from MoosJaw seems ever so slightly more lofty. Even the label inside the coat seems of higher quality. I do believe the one from MooseJaw was manufactured earlier than the one from Amazon. So it's possible MH gear changed something slightly. Is not a huge difference, just something I thought was interesting to note. These are my first Down jackets ever, so I didn't know what to expect. And it's only by chance I had two jackets from two different outfitters to compare. Anyways it's a very nice coat, I would buy it again probably. And For light weight backpacking, it's hard to beat the warmth and pack ability of these jackets.
The only weakness about these is, they CANT get wet!
