Great for layering
This jacket has come in quite handy for sports events, where the wind picks up and the temp drops. I've used it for just what it is, a hoodie. It's very thin and fits under any jacket and doesn't feel poofy. I keep it packed in my car for games, along with my rain jacket. I don't see that it's 650 down though. It is not a winter jacket. I'd say it's an "add-on"

great stylish jacket
I saw this jacket on a friend of mine and fell in love with the light weight of the jacket. It squishes up into a small bag so it is great for travel. It also holds up well on windy days. I am small-5'3 and 103lbs and the xs is big. I kept the jacket as I love it and can layer sweaters or gym clothes underneath. I would definitely recommend it!

Perfect except leaks down
This incredibly lightweight and warm down jacket looks great and has best fitting hood on any winter jacket I have ever owned. It am plump size 12-14 and the large fits well. It is warm even in windy cold blizzard and has packs very small & is very light. Problem is that it leaks down. This is in comparison to my Patagonia Down sweater which doesn't leak but is heavier and not as warm.

gift to myself
I found this jacket in a store, then spotted it for less at Altrec. What sold me on it is the fact that it's down, and warm, but so thin and light you don't even feel like you're wearing a jacket. The fit is slimming. I'm 5'7", 145 lbs, got a large for layering, even though the medium may fit better. It has pockets inside for safely stowing stuff. The hood is comfortable and warm but doesn't get in the way when I'm not wearing it. It is shedding some feathers but I expect that won't last long. It is toasty for chilly days and blocks much of the wind. Down used to mean noisy, stiff, puffball, but not with this jacket. I'll probably buy the vest, too.

Aria Hoody
I got this jacket because I own the vest,which I LOVE. It fit's perfectly. I'm 5'2" 105lbs. and got an XS. It's not bulky and packs small. I live in Denver, CO and it's great with a cashmere sweater underneath during the winter on colder days.
