Atom AR Hooded Insulated Jacket
A down jacket may seem like a good call when it's cold and you're getting gear ready at the trailhead, but you're going to be a hot, sweaty mess by the time you're on the trail and your heart rate is up. The Arc'teryx Men's Atom AR Hooded Insulated Jacket insulates when you're getting gear lined out for the day's objective and remains breathable during the approach, so you aren't stuck with a soggy, useless down jacket before the sun is even up. The Atom is insulated with Arc'teryx's Coreloft insulation, which consists of highly crimped and siliconized polyester yarns that are breathable, packable, and water-resistant to retain insulating capabilities when confronted with light precipitation. If it does start to rain or snow, then the Atom can be worn comfortably as midlayer under a shell for an added dose of warmth.
- All-around midlayer for the trail, skintrack, or crag
- Water-resistant synthetic insulation is highly breathable
- Durable Tyono fabric treated with DWR for added weather protection
- Compressible design packs away for easy storage in a backpack
- Can be worn as a midlayer during cold ski days or rainy hikes
- Vancouver-based Arc'teryx uses the mountains of British Columbia to inform its clothing designs
- Item #ARC004D

Let me start by saying that I have many jackets. This is my new go-to jacket. It used to be my Outdoor Research Cathode but my dog chewed that one up... This jacket is plenty warm above 20-25 degrees with a t-shirt under. The face fabric is much more resilient than my nano-air or the LT version of this jacket. Warmer than my nano puffs. The build of this jacket is superb and high quality. I am interested to see how the jacket holds up to normal wear. I am 6' 3" 245lbs and the XXL fits PERFECT. Best fitting garment I own.

Not a winter jacket
I am looking for an everyday jacket to wear in Syracuse that could also be used for steelhead fishing, dog walks in the snow, watch watch my kids hockey games, etc, This is a lighter weight jaclet that would be good for fall and early spring, but is not going to cut it for the. Older temps. I'm 6'0", weigh 205 and this was too small. Other jackets I have by these guys in L fit fine

The 'Perfect' jacket
This is my first jacket from Arc'teryx. Excellent build quality, fits perfectly & right amount of warmth. Holds up very nicely with just a shirt till 30s. even in windy conditions. All this without looking bulky !! :-) You might want to layer it with a flannel for sub 30s ( if you don't like bulky layering like me ). For the quality, the price is absolutely worth it. Looking forward to have more from Arc'teryx collection.

One of the best jackets you could own.
I’ve owned this for almost 5 years and it has never let me down. While it isn't built for rain,(I believe it is repellent rather than waterproof), it has kept me dry in many showers I was caught in. Plus it is great on cold windy days and snowy ones too. The construction is great from top to bottom, and doesn’t cut corners at the hood like some other jackets. You could wear it without a layer to around 40 Fahrenheit. Under 30 you’ll want to switch to a heavier coat, though depending on your layering you could still use it. I wouldn’t recommend it for the teens or near to, or subzero winds. Bottom line- This is a fantastic coat you can count on for years. At 5 years old, it looks good, keeps you warm, and has a nice style that isn’t dated. Highly recommended for casual or moderate activity in the cold. I don’t ski or hike, but it would probably serve you well in those activities given its construction and mobility. I bought mine in Orange and like the color. Hasn’t faded.

Thanks so much for the awesome review Emery! Super stoked that you love your new jacket!

Great fit and looks really good in Proteus. Did well for me in 40-50 weather in NYC. Super comfortable! Excited to wear it in Alaska!!
February 12, 2019
Awesome jacket! worth the dollars!
February 4, 2019
My husband bought this and it has quickly become a staple for him. The Proteus color is really great, and it fits him perfectly.

Super warm and comfortable. Great all around jacket. Happy with this purchase for sure.

After much pressure from my peers particularly a lovely lady in my life, it became time to join the Arc'teryx family. After collecting many cans, converting our power usage to solar and cutting our cable, I was able to acquire this amazing jacket. #Wortheverypenny In all seriousness this jacket has been my go to for walking to work every day. It has been quite warm but somehow breathes as well. I used it as my mid layer for skiing, but quickly removed it as I overheated. It does repel rain adequately, Maybe not all day, but for jaunts in town it has done the job. Overall very happy with the purchase. Hoping its not too hot for 50-60 degree days. Could maybe be bit longer as it sits right at the belt line.
January 5, 2019
I wear this probably 40-50 days during the winter. It is the best!

Great fit. Comfy but not loose. Love the lifetime warranty and great all around jacket.

5-11, 180, longish torso, size M Really wanted to love it like the LT, however it just didn't have that perfect fit. Too short (hits right at the belt line) and a bit too boxy (the LT is far more form fitting and flattering). Felt warm enough and had a nice quality too it. Had to return based on fit.
January 31, 2019
So, I'm 5'10" and about 200, but muscular. I've got a bit of "extra" around the midsection and wondering if the L is going to cut it. Input?

best all around jacket I own
This jacket can be worn when it's 20 and it can be worn when it's 65. The combination of the shell and ventilation makes it the most diverse jacket I own...and I own a lot. It is SO light, that it can easily be worn under a jean jacket if your doing your outdoor garage (or lumberjack) work. If you come in from the outdoors, and want to continue wearing this indoors (where it's a little cool) it's perfect. (e.g. hockey games). Also very comfortable driving in it. . It is also insanely packable. (I have worn this jacket all winter...but only as an urban warrior, and not using it as a lumberjack or snow boarder I wear a medium in EVERY other coat I own...in this one, I'm a large. The zippers are not high quality.

I bought this jacket hoping for something warm to wear on my morning walk with my dog in the harsh Michigan winters. Jacket totally fit the bill. I am 5'9" 195-200 so I'm borderline Large or XL in most jackets. The XL fit was just right for me. With this jacket- just enough room to feel comfy. I really loved the jacket- but ordered the red.. The pic on the internet led me to think it was more of a brick/dark red... upon receipt the jacket is very bright red. Sounds picky... but I just din't care for the color. Other than that.. excellent jacket, very warm, comfy, looked and felt like it would hold up to wind and rain/ wet snow.

Super Warm and Light! Odd Sizing
I will admit that I intend to use this jacket for urban purposes 80% of the time. My Large weighs in at 480g and is impressively warm. I love the cuffs they create and attractive smooth and comfortable seal around the wrist, very clever design. I wish they had applied the same concept to the bottom as the hem bunches awkwardly with the slightest pull on the cinch cords. The hood functions nicely with a cinch cord that functions well. As another review I read mentioned, it does seem odd that the jacket will unzip easily if you pull the sides apart when partially unzipped. Perhaps this is intentional, I would welcome a comment if someone knows why it does this. My biggest criticism is the sizing. I should fit easily into a medium which was the first size I ordered, but the forearms were way too tight, I could not comfortably wear anything but a t-shirt or fitted base layer under it. Also the back did not seem quit wide enough for me to cross by arms without feeling it pull. I ordered the large and its arms and back are perfect but of course the waist and midsection is considerably looser than I would like. On the bright side I can now comfortably fit a fleece layer under it. I just find it odd given that I am fairly modestly built and that it is a regular fit, that the forearms and back would be so restricted. To sum it up, I love the jacked but if you intend to wear this jacket with regular street clothes around town, or as an outer layer with a fleece, I would recommend ordering a size up.

My Bestest Jacket!
I can't say enough good things about this jacket. It's light enough to be a heavy mid-layer but can stand on it's own in the cold if needed. I happen to be the friend mentioned below who looks forward to the cold so I can put this baby on. It's great! Do yourself a favor and get one. A small worked great for me

My Best Jacket
This coat is my go to coat and i love it. I've worn it several times in very cold conditions without any layers on top and have still been warm. If you're looking for a daily coat or a warm midlayer, this is a great option. While it's expensive, it's worth the money. Make sure to check out the size chart when you are ordering the coat. The arms on Arc'teryx jackets are typically a little long. My medium fits me great! A friend recently purchased this coat due to my suggestion and said that he looks forward to cold days so that he can wear this coat.

Would this work as a suitable outer layer winter jacket for a typical Minnesota Winter? (Ranging from 32 to -15 degrees (F) with wind). If not, which Arc'teryx jacket would you recommend for those conditions? (under $400)

How does the AR fit compared to the LT? I normally wear an XL in Arcteryx products and that usually leaves me ample room to layer underneath. I tried on an XL Atom LT at the store and it was too short in the waist. I couldn't lift my arms above my head without the jacket riding up above my belly button. So does the AR have a longer length? Also, I know the AR won't be as breathable as the LT, but is it breathable enough for moving quickly through the mountains with a gore-tex shell over it in 20-30 degree temps? Cheers! IN response - I understand the concept; I am asking about specifics. I know the AR will be cut a bit looser, but is it any longer from shoulder to hem than the LT. Also, is the AR breathable enough for Moderate to High output activity? Lol and I accidentally marked the response as helpful, couldn't undo. That was an answer I could (and have) easily gotten from the product descriptions.

Hey Sean, Trim-fitted garments share the motion-friendly traits with our 'Athletic' fit garments, but are patterned with lower volume for reduced bulk. These close-fitting pieces layer well under other garments. Athletic fit utilise anatomical shaping and gussets to enhance motion by minimizing excess bulk. Easy layering under or over each item extends seasonal versatility and comfort.

Assuming sized up to a medium, how well would this work over a small Atom Lt and a medium Alpha Fl as a belay jacket during Ice climbing/cragging?
November 22, 2015
Is this piece designed to be layered over the atom lt? If so, do the sizes run true in both pieces when layering?
November 22, 2015
Hey Mark, The Atom AR has a different more durable face fabric (Gossamera) compared to the Atom LT and it is an athletic fit which is Arc'teryx's standard fit. The Atom LT is trim fit. Also, the AR has more synthetic insulation so it will be warmer. Both are designed to be layered under a technical shell.

5'11 170lbs what size do you think
November 23, 2015
I'd guess medium. But that's a super rough estimate. Go off your chest size rather than height and weight.

Hey Adam C. I'm about that same size, I would go with Large

How does this jacket perform in light rain?
October 1, 2015
Lee, This jacket will do great, in light rain! It's definitely not meant for, or priced for, a big down pour. But, it will get you through town in a light, but consistent sprinkle. More questions? Let me help! Emily Jenson Expert Gearhead 801.746.7587 firstname.lastname@example.org

it will manage but definitely not made to withstand more than a trickle. If you do manage to get it wet, CoreLoft will stiff give you heat unlike down jackets.
February 17, 2015
How does this jacket compare to the patagonia nano air or nano puff regarding warmth, breathability, wind resistance, etc? Thanks
February 20, 2015
Hey Roberto, the Atom AR is going to be considerably warmer than either of those pieces. The AR uses several heavy weights of Coreloft continuous insulation (120/80/60, body/arms/hood) and has a non-baffled construction, so there are fewer seams for wind to get through. The Nanopuff uses 60g insulation throughout and is baffled, so will be considerably less warm; the face fabric of the Nanopuff is less breathable than the Atom. The Nano-Air is in entirely other category, and is designed to be as breathable as possible to keep you warm while active; the shell fabric and insulation are intentionally designed to be air-permeable. You would need a light shell over a Nano-air to be equivalently warm to either the Nanopuff or Atom in any sort of wind. The warmth scale here is Nano Air > NanoPuff >> Atom AR. If you're looking for a more breathable Arc piece, the Atom LT is a good choice, as it has uninsulated fleece side panels designed to vent heat while moving, but again, in a stiff wind you'd need a windshirt or light shell for warmth while static.
