Arc's multitasker.

Arc'teryx made the Atom LT Hooded Insulation Jacket versatile for year-round mountain adventures from climbing to skiing. Its Tinthan shell is light yet durable, and the DWR coating sheds rainfall to help keep you dry on hikes and backpacking trips. Breathable Polartec Power Stretch side panels make sure you can move around with complete freedom of motion, whether you're wearing it as a midlayer or an external shell. Synthetic Coreloft insulation retains its warmth in wet weather, and the adjustable StormHood slides over helmets with ease. Arc'teryx also added an adjustable hem, a zippered internal pocket, and two zippered hand pockets for your convenience.

Great versatile jacket. Can be used from around town to hiking to layering for skiing to makeshift pillow at camp to makeshift blanket when ur stuck in an airport lol. Great warmth to weight ratio, this thing packs the heat given it's size/thickness. Fits nicely under a hard shell (I have put it under my sidewinder ), and packs into its own pocket. I also have the nano puff, this arc jacket is def more form fitting and trim cut than the nano. Order your usual size. Highly recommend, esp if u can grab it on sale.

I've got a nano puff (no hood) and would like something a bit warmer. The Atom is on sale everywhere right now. How would you say the warmth compares to your nano puff?

Responded on

you're basically talking about primaloft (nanopuff) vs. coreloft (atom). coreloft is arc's proprietary insulation, while primaloft is more of an industry wide material. To be honest, you won't notice much difference in warmth between these jackets, they are very similar in that aspect. I would again reiterate that the atom is more fitted, so if you're looking to put it under a shell, def get an atom. disclosuer, my nano is a few years old, it's not the new nano 'air' model

this may also help u

Best insulating layer.

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

This jacket is one of my favorites. I can wear it in the lower 60s all the way down to the upper 30s, and even lower if I use it as a layering piece. The zipper is super smooth, the material is durable, and I particularly like the breathability of the stretchy material located on the sides. If you want an all-around, light weight, insulated jacket, look no further!


What is the color of sleeves cuffs on green color? On official page I notice that they are grey but on attached picture i noticing they are same color as body color.

Please let me know.


Responded on

I would go with the image that is on the official Arc'teryx website, which shows them as gray. Your image may be an older version of the jacket, or maybe a knock off.

Have a question about the Carbon Copy color. Is this actually the black color? In REI and a few other sites like EVO, the carbon copy color is listed as black and their Carbon copy version has the blue trim and interior color. So which one is correct?

Responded on

According to Arcteryx's site, the Carbon Copy has a more matte finish and the red interior.

Responded on

Carbon Copy is a dark, raw carbon fiber color. Think a shade lighter than slate. The red inside accents it well. This comes from someone who has tried on the jacket.


Can someone post real pictures of...


Can someone post real pictures of POSEDION & KYANOS color. I am interested in blue but hard to pick the right blue ;)

Thanks for help!

Responded on


The colors uses are color-correct and good references. Poseidon is a darker blue, almost more of a "Navy Blue." Kyanos is lighter than Poseidon.

Responded on

Still would like to see how Kyanos look like compare to Poseidon. Looking this jacket same color - Poseidon do not look very dark blue to me:

Kyanos is pretty much the same colour as Olympus blue. I put the 2 jackets together and Kyanos was the slightest amount darker in hue.

New Atom LT is a worthy upgrade for some

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

Simple: one of the most versatile synthetic pieces you can buy.

Competitors: BD Access Hybrid/LT, Patagonia Nano Puff, OR Halogen Hoody

The Fall 2014 Atom LT includes a new hood, that uses the 'ballcap' adjuster behind the head- identical to the one used in the Cerium LT hoody.

It moves with your head, offering unparalleled peripheral vision.

It's less warm than the Nano puff, but more versatile. Awesome mid layer for skiing the cold days, or on it's own in the spring. Used it backpacking, walking around town, and on a bike. The fleece lined pockets are a greatly appreciated bonus.

Responded on

Patagonia is releasing new Nano puff called Nano Air. I think this jacket will be better compared to Atom LT (which I love btw).

See here , looks really good:

Responded on

Atom Lt also got a little longer in the torso than the previous version

Responded on

The Nano Air is nice, but lacks the internal pocket, fleece lined hand pockets and the windproof material of the jacket. Its outer material is 60 CFM- kind if like a softshell.

The Atom LT will be much more protective and offers a better hood

New Atom LT

  • Familiarity: I returned this product before using it
  • Fit: True to size

This is not a review of warmth or durability. I ordered because I was curious about the new model of this great jacket.
In this revision they changed the fabric which is hard to tell by looking at it. One person said this is the same fabric used on the Atom SV.?? It is still very thin, I took a close up for detail of fabric. The hood has changed to fit a helmet, I can't test the fit as I don't have a helmet to test with but I know it's bigger than the previous and DOES include an adjuster on back of hood which cinches sides and top of hood at the same time. Inside pic of hood shows where the cord runs. They also changed the stretch cuffs by making the cuff shorter. I don't have my old version to show a side by side comparision but if you have the older one you can see the difference. The fit seems a little bigger to me but maybe not. This is the carbon copy color, similiar to colors in the past and not as dark in the stock photo.
I hope this is helpful for someone looking to purchase this updated model. I won't be keeping because the hood is so big for use without a helmet.

New Atom LT
Responded on

Any idea if it is cut longer in the front? I have always found the medium atom LT too short in the front (Larges are perfect in length- but too big in the torso)

Responded on

I don't have my older version to compare but the length seems the same. Others can add in if they disagree.

Responded on

Paul, the cut is the same. BTW, I messed up on the new Atom LT- I have the LEAF version of the new Atom, which uses the Gossamera fabric, a less packable but more durable fabric than Tintham- which is what the NEW (standard) Atom LT uses.

The Gossamera is found on the new Atom AR and former on the Atom SV.

Responded on

Thanks so much for the pics. BC really needs to update their stock photo. You have done a service sir! Question: the lining is red, and NOT orange, correct?

Does this model have the hood pull...

Does this model have the hood pull adjuster?
I notice the new model on the arc'teryx website has one but they are only offering three color options on their website. Is this the same model?

Responded on

Yes it does. I ordered one out of curiosity and to provide a review since no one has yet. The hood is bigger than previous model for helmet. I don't have a helmet to try with it though. I will provide pictures and other thoughts when I have more time.

Not really a question or review but just...

Not really a question or review but just thought it was curious how Arcteryx let BC sell this before they even release it on their site. I am dissapointed as I have been waiting for this new version to come out and see it has a helmet compatible hood and they changed the face fabric. I would like to know how people like the new fabric but I won't be purchasing this one since I don't wear a helmet for my activities and the original hood was even a little big. I hope others like it. I just wish this company made more jackets with normal hoods, though I guess they are aiming at a specific group of people with their gear.

Responded on

The new fabric is identical to the Atom SV. It's more stout, and less prone crinkling.

I would like to know if this jacket is...

I would like to know if this jacket is waterproof and if it can provide me enough warmth.I am intend to use it in mid mountaineering expeditions and in cold weather conditions.As I will spend the next winter in Northern Europe I would like to know if it is suitable for the purposes I need it for.

Responded on

This is more of a mid layer for cold weather and outer for cool weather. I would read reviews on the original model, which is still for sale here. I don't know about this one but the other was not waterproof and the specs for this one says it has a thin shell with a DWR to shed rain, but I doubt it is waterproof since it is not a gore-tex shell. Hope this helps.
