Perfect mid-layer for the lifts

  • Familiarity: I've put it through the wringer
  • Fit: Runs small

My Atom has become the jacket that I wear almost every day. Comfortable, lightweight, and warm. For me it's fine as a stand-alone jacket except in the dead of winter. In my opinion it packs relatively small considering it's not down. The hood could use a cinch for when you're not wearing a helmet, but when I'm wearing my climbing or snowboard helmet it fits great, especially under the cinched hood of my hardshell. I'm typically size L (I have a Large Alpha SV) but the sleeves and waist were a little short so I went with the XL. The fabric is thin and doesn't last long against sparks, so don't be stupid like me and wear it around a campfire!

Very very close to perfect

  • Gender: Male
  • Familiarity: I've used it several times
  • Fit: True to size

This is a great, almost perfect, mid layer for very cold temps, or a good outer jacket during spring/fall. I come from using a minimal down sweater almost daily except during the height of summer. In Spring or Fall this jacket works great as an outer jacket. The breathing side panels do make a difference compared to the down sweater I was wearing, the Atom being less clammy feeling. Together with the less 'sticky' outer fabric this just makes me that little bit more comfortable.

Had some mild rain and DWR works great for now. Main reason for synthetic for me is it will be easier to wear under a shell and not worry about it getting compressed or wet as much as with a ultra light high fill power down shirt.

I'm 184cm and 72Kg (6.1/160) and I'm often in between a Medium and Large due to broad shoulders. Got a Medium and it fits great. If you want to layer a lot under it, or you like a looser fit, you would probably like a Large.

I have a Atom SV (also Medium) and the two are sized to be worn together (the LT with the tighter fit, the SV looser) so no need to adjust sizing if you are thinking about going that route.

The hood is not as bad for me as for some other people. I've been in stormy winds twice and although the hood wasn't shut tight and let in air, it did stay securely on my head. I feel a cinch cord in a newer model would be well worth the weight though and really make the Atom LT 100% perfect for me. The hood on the Atom SV is perfectly adjustable with the cinch cords on the sides and in the back.

The remarks about the cuffs are not exaggerated. It's a sign of good design when you get something you never knew you needed. Arc'teryx is expensive but their attention to detail, their fabrics, and their cut (the fit) is the best there is.

Does the 2014 model have the hood cinch...

Does the 2014 model have the hood cinch cord like the LEAF series? It would be nice if BC would carry the LEAF series. Thanks.

Responded on

I haven't seen it myself, but heard from two people that went to a trade show that it would have a hood adjustment for 2014.
I thought in the back, not on the sides but can be mistaken.
Although I don't think the hood is as bad as a lot of people seem to do, I do think either way of hood adjustment would be a definite improvement and make this hoody perfect.

Responded on

I have the 2014 LEAF Atom LT Hoody in Wolf, and can tell you that it has a drawstring identical to the Cerium LT Hoody. I believe the drawstring hood comes to civilian versions in Fall 2014

I bought alt yesterday and it's not the new version with a hood cinch yet....I will prob return mine if the hood cinch model comes out in the next month.

Responded on

Confirmed with Arc customer service today, they are making changes for fall of this year but they wouldn't say what was being changed.

Responded on

I would honestly just get the LEAF. It is virtually the same product as the 2013 model except they have the bigger pockets and much needed hood cinch. From an aesthetic perspective, I actually like the LEAF more as it has a non-reflective logo that just kind of blends in with the rest of the black jacket. Then again, some people love the color variety. It's really your call. I have a 2014 Atom LT LEAF and I love it. I'm 6'0, 160 lbs, I got a Medium and it fits me perfectly. I can even put a nice thin fleece underneath for when it gets a little chilly out.

Responded on

Is the fit exactly the same for the standard and the LEAF version?

Sizing

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

Great jacket. Everything has already been said about the features. 5'11" 170lbs and I wear a large. The medium felt too tight for me around my neck and too short in the front. If I was getting this jacket solely for the technical aspect the medium might have been a better choice, but for me it will be used for around town also. Call me vein or self conscious, but it's kind of lame when your mother asks if you are wearing your wife's jacket because of the fit.

In a recent mountain hiking trip where I started at a point where temps were around 74-F and ended at below 50-F I carried this jacket packed in the pouch it comes with. As such it is about the size of a Nalgene liter bottle. It is light so it didn't bounce much as attached by a small belt on my Lowepro camera belt bag. Carrying it that way makes it instantly ready for when I need it and I didn't have to dig in my pack for it. At night when it was close to freezing I wore only a shirt over a thermal top under this jacket and that's what wore to sleep in a tropical grade sleeping bag.

(Btw, this is my second review. I'm the guy who sew the edges of the hood so it fits more neatly over my head.)

Great Mid Layer, great fit w/Beta AR

  • Familiarity: I've used it several times
  • Fit: True to size

I tried out several mid layer options by Arc'teryx including the Nuclei and Atom SV, neither was a good fit. The Atom LT is extremely light and a great mid layer that I wear over a fleece on colder days.

Best light insulated jacket ever!

  • Familiarity: I've put it through the wringer
  • Fit: True to size

one of my favorite jackets - use it all the time! Perfect fit, really light and packable, comes with a bomber DWR treatment that lasted over a year, so nice fit that you don't notice you have it on. Really good breathing when used as a middle layer under a shell.

Great jacket, hood too big though

  • Familiarity: I've used it several times
  • Fit: True to size

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.

Top of ITS CLASS

  • Familiarity: I've put it through the wringer
  • Fit: True to size

Hands down the best lightweight, packable, jacket I own. If you are looking for a great lightweight jacket to face windy elements or a rainy Vancouver or Seattle spring...don't look any further.

great jkt. ligtht weight great during this past "BLAST" of cold air, glad i had it

has anyone compared this with the new...

Posted on

has anyone compared this with the new arcteryx nuclei? seems like that piece would be better as its both lighter and warmer (80g of Coreloft instead of 60g).

Responded on

You're totally right on that. When comparing the two the Nuclei would be the better jacket because not only is it lighter, but it also has more insulation going on with it. However the Atom does have a DWR-coated nylon shell which is a bit more wind- and water-resistant. Personally I'd still go for the Nuclei if it were me, but both are solid options!

Responded on

The atom is also cheaper, it has the breathable side panels, and stretch cuffs, and this hooded version has a draw string waist, not sure if the Nuclei does. Depends on what you are looking for.

So far my favorite jacket I own.

  • Familiarity: I've used it several times
  • Fit: True to size

The atom lt is a great jacket just read all the reviews. I am a small guy at 5'5" and 120 pounds. I would really like them to make it in an extra small for hobbits like me. But it is a great jacket and the small still fit well.

A warm cloud

  • Familiarity: I've used it several times
  • Fit: True to size

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.

Great piece, must own

  • Familiarity: I've used it several times
  • Fit: True to size

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 make everyone buy one

  • Familiarity: I've put it through the wringer
  • Fit: True to size

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.

Solid performer

  • Gender: Male
  • Familiarity: I've put it through the wringer
  • Fit: True to size

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.

Functional but not overly special

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

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.

Wonderful Jacket

  • Familiarity: I've used it several times
  • Fit: True to size

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.
