Positive Reviews:

If you're looking at jackets of this ilk, you're probably comparing this to North Face/Patagonia/etc. Or, if you're a sucker for Arcteryx, you're comparing it to the Hyllus. What's the difference?
The Hyllus is more water resistant than the Atom. Also, because the Atom has side breath panels, the Hyllus is more wind resistant. If you're wearing it under another jacket, the Atom is more flexible and softer--and thus easier to use. By itself in wet or windy weather, however, the Hyllus is the way to go.
How good is this jacket? So good that my wife wanted one, once she saw how much I loved it (just like my Hyllus).
Having the Atom and the Hyllus, here's how I pick:
1) Wearing it under a shell? Atom is softer and more flexible. And warmer (when under a shell).
2) Wearing it by itself in rainy or very windy weather? Hyllus is more water and wind resistant (because the Atom has vented side panels).
3) Wearing it in the cold when rain and wind aren't an issue? Atom is warmer than Hyllus.
It's a great jacket--and if you're worried about hood or no hood, get the hood. It folds down to nothing, and is never in the way.

This was a jacket that I avoided for a while, and I wish I hadn't. I was skeptical about the hood, and I have always been a fleece guy. This hoody completely wow'd me with how it fits, and more importantly how it performs. This jacket fits me perfectly at 6'3" I am an XL in all but Arc shells. The drop tail is great for coverage, and the hood is better than a hat in most cases... if not a little goofier looking in public. I have worn this alone over a shirt in 30 degree snow and light sleet... the DWR and face fabric are great for that, but I wouldnt want it in a rain storm. Under my Sidewinder shell this thing is a beast... makes it like an insulated jacket with the hood and all being covered. The neck zips up pretty close to my chin, so offers nice protection from the weather. I don't climb, but I use this for a skiing mid layer and general jacket for quick trips. It's not cheap, but its worth every penny and more. The colors are really sharp too this year, which was just an added bonus.

I haven't taken this jacket out backpacking yet, but for general around town use it feels wonderful. Lightweight, soft, and keeps the wind out decently well. It is also quite warm; wore it in mid 30s weather with only a t-shirt underneath.
The pockets are a bit high up for me, and are pretty small, but its not a huge issue for me. If you really like your pockets though you might want to reconsider, or try a larger size possibly. The zipper is somewhat loose sliding as mentioned by others, but I don't see it being much of an issue. The wrist cuffs are pretty snug on me with the medium, but nothing uncomfortable. Will work good with gloves on.
Follow-Up: Love this jacket, fits amazingly well, and is very warm, but vents heat nicely to keep you from overheating. As other have also said, I can wear this with only a T-shirt is 30 degree weather and feel perfectly fine. Excellent fit as well, no baggy parts, nothing that feels too tight, just right. Would purchase this jacket again in a heart beat.

I bought this jacket to wear as a stand alone piece for spring and fall climbing. When I put on this jacket I immediately felt my body heat radiating back at me. It was like slipping into a warm cloud. This jacket is incredibly light, and is easy to compress so you can always have this on you when in the outdoors. I've been out in freezing weather with just this on and a t-shirt. I wouldn't recommend it, but I stayed comfortable. I really like the slimmer fit, being a skinny guy it's nice to not have the bottom of your jacket box out like an awkward dress. The longer cut backside is sweet too, adds a little extra length to the rear so you can extend your arms above your head and put those ice axes to work without the fear of an exposed caboose. Love this jacket, I'm wearing it right now, breathes like a champ too.

This jacket is useful in almost all conditions when physical activity is not involved. It vents a little, but if you are hiking, you'll shed this layer eventually. The gamma mx/ other softshell jackets would be better for ventilation.
That said:
If you live in an urban/suburban area like most of the US, this jacket will be your go-to once you've passed the sweatshirt-weather stage. I own 1, my brother owns 3, and now 4 of my friends bought one.
Long Story Short: full price, half price, double price... you won't regret it!
I havent washed mine for the two years I've owned it. I need to wash it now because I got Christmas Tree sap all over it, but i'm still holding out to see if it'll clean itself. All this said, it still does not smell at all.
Only complaint would be no hood adjustment, which you can have if you ante up to the SV, however that's basically a parka.

I own at least 18 pieces of jackets/shells accumulated over time and this is my third Arcteryx coat (with a fourth one on the way; I have an eye for quality, an expensive vice I must admit). It quickly became my favorite for its fit, light weight, and especially packability. It is flexible all-around as I can mix and match with just about any sweater or even down jackets in my closet to be warmer if needed. I can put a shell on if it gets too wet.
One complaint is that the hood is too big for my head and "de-hood" easily when in use especially when it is windy. So I pinched the hood opening by about and inch on both sides by sewing the edges as you see in the picture. It is a solution that works for me quite well. It took some effort, but because of that I like this jacket more.

This was my first Arc'teryx purchase ever and boy was it good. The jacket is filled with primaloft, which is a synthetic material that makes it super light, but keeps you warm. If I have to go anywhere this is the jacket I go to the most. It's really lightweight and does a good job keeping the wind out. Also, I've washed it several times now and it holds up pretty well in the washing machine. I always hang dry it, it might say low tumble on the label, but it's been in great shape for over a year now. Arc'teryx made a jacket for everyday use. I wouldn't say it can handle any extreme weather, but for general use, it's PERFECT!

I love this jacket, I've used a lot of synthetic insulation jackets and this one is my favorite by far. Its really warm for its weight, and is also very light and packable. I was wearing this during the windiest week SLC has had all season and i could not be more impressed. It kept the wind out and kept me warm. I have yet to ski in it but I believe itll hold up great. My only complaints about the jacket are the hood and zipper. The hood its a bit loose and the zipper has absolutely no resistance. If you grab the hood the wrong way, itll unzip. But overall a great jacket that I would highly recommend.

Brian Pfaff at on 11/25/2013

I wear this jacket more than any other piece of clothing I have.
It sheds wind and water pretty well, and it is great as a standalone in milder fall/spring weather. Although the underarms are meant to breathe more, the insluation is so effective I find almost any exertion level quickly raises my core temperature. In colder months I throw a baselayer and midlayer fleece underneath or a harshell over the top (depending on conditions) and can comfortably spend a day working/playing outside in sub-zero temps with mild winds.
I'm 6'1", 180 lbs, and the large size feels tailored.

I purchased this to replace my mammut broad peak jacket. Although not down insulated it seems to work quite well. I've used it in the Swiss/ Italian Alps in March, Oregon and all over the east coast. My only complaint is that the hood isn't adjustable. It seems to be the one thing lacking. Not incredibly warm compared to down insulation, but overall a solid jacket that could use one or two improvements.

Neutral Reviews:

Decent enough layer but not overly noteworthy. Hood is too voluminous for my liking and would be better with draw cords. A bit baggy around the midriff for the more slender amongst the large types.
I tried this on with a shell on a hot Sydney summer afternoon and did not cook so sort of wondering about the thermal attributes but will test this out more in a winter environment in two weeks time.
