I purchased this jacket along with 4 others and picked the best from all of them. This jacket was 2nd place. I will tell you why:

Its freakin sweet warm, light, compressible, fleece lined pockets, only 1 zipper (not 2 like every other jacket - which is more annoying than useful), and a good hood. My review probably wont even give the Fitz Roy enough credit... this jacket really is good.

So why didn't I keep this jacket... it was up against the Rab Neutrino Endurance.

Well this jacket is really nice, the 800 fill down is extremely warm. So far I have taken in out in-14 degrees Fahrenheit with just a t-shirt under and I don't notice the cold at all. Well, except for my face, legs and feet lol. The only thing I have found to be kind of a down side is how light weight the outer material is. I am a little scared to walk by a branch with out it ripping. The only other thing is, is the arms on the inside have very minimal down, on the outside arm it has plenty, but the inside of the arms have hardly any down. Not that I have noticed my arms getting cold, I don't know why they would design it like that, maybe because it is made in China. All in all this jacket is really nice and comfy, for all of you in the lower 48 you can't be worried about the cold. Here in interior Alaska, I really have to think about warmth, thus why I am so touchy on the amount of down. Now, the hood is really nice, unlike a lot of other down hooded jackets, when the hood is tightened, it actually helps you see better, not just engulf your head.

The Fitz Roy Hooded jacket is a premium item if you are looking for some serious insulation. I have worn this jacket with nothing more than a T shirt underneath, stepped outside in frigid Wasatch Front winter weather (10 fahrenheit and colder), and been perfectly comfortable. Make no mistake this is serious equipment to battle the cold, especially if you live in a mostly dry climate. Although the jacket is water resistant, I would be hesitant to wear it in consistent rainfall. The only other jacket I would consider in similar application is the Himalayan Parka by North Face. I give Fitz Roy the nod here due to packability. Patagonia fits pretty true to size across the board in my opinion, I wear a medium (5'10, 135 lbs). This is a fantastic addition to your closet if you want to give old man winter the middle finger.
