Atom AR Insulated Jacket

When high-alpine adventures are in your future, look no further than the Arc'teryx Men's Atom AR Insulated Jacket. The DWR treatment lets this piece work as a standalone layer when things are really cold, shedding small amounts of moisture as well as keeping the abrasion-resistance as tough as possible. The athletic cut of the Atom lets it be used as a midlayer insulating piece as well, since things can't always be as dry as you'd like. Coreloft insulation throughout the jacket delivers plenty of insulation for your next summit bid. Arc'teryx distributed the insulation heavier throughout the body and lighter through the arms since, as the old maxim goes, keep the core warm, and the limbs will follow. Zippered pockets for your hands, and one for your media, lets you keep your valuables and necessities at easy reach.

  • Insulated jacket designed for active adventures in the alpine
  • Wind- and water-resistant shell sheds raindrops and snowflakes
  • Body-mapped Coreloft insulation gives more warmth where needed
  • Adjustable hem stays secure under harnesses and backpacks

Love it

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

I bought this jacket for my brother and he loves its warmth especially since it doesn't wet out like down jackets. He wears it most days of the winter and occasionally in the spring and fall. It’s the perfect weight and easy to wash and care for. He's 5'7 and 155 and went with the medium.

Excellent above 40F

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

Ive owned this jacket for about 6 months now I think. I live in the DC area and wear it regularly. The durability is top notch, not single sign of abrasion from packs, seat belts, getting in and out of military airplanes and helicopters, or from the 90 pound German Shepherd that loves to jump up and put his paws/claws all over you after coming home. There is no ventilating heat from the jacket as with the Atom LT so things can get toasty fairly quickly if on the move. I have worn this in in sub 40 degree weather and would have preferred a down alternative. Mated with either a Patagonia thermal weight zip neck, or an Arcteryx long sleeve captive polo, merino wool scarf, merino wool beanie, and deer skin fleece-lined gloves, I was still cold in a moderately static environment. The majority of heat escapes through the collar, so when wearing a scarf, make sure it is also not too bulky or you will have difficulty zipping all the way up. The zipper will also migrate downwards in this situation if the scarf is too big unfortunately. I have also noticed that after a few washes the jacket is no longer as warm as it was when I first bought it. I'm 5-5, 165-170 pounds of athletic build and the Medium is spot on for fitment. I highly recommend this piece for above 40F temperatures with moderate levels of physical exertion.

My new favorite jacket

  • Fit: True to size
  • Size Bought: Med.

I love this jacket. It doesn’t feel like much, but boy does it keep you warm. And I’m really impressed with how well it holds up against the wind. Definitely my new “go to” jacket. I originally tried the LT version, but much prefer the AR. It Makes a bit of a rustling noise, but not enough of an issue to take off a star.

Great jacket

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

Its nice and warm and i really love how the cuffs hug your wrists and prevent the sleeves from sliding up your arm

Such a versatile layer

  • Size Bought: Medium

If you are a slim jim like myself, you are probably always looking for new jackets and shirts to fill in the gaps of your insulation reserves. Having very little natural insulation makes achieving optimal temperatures quite difficult, but this little jacket makes it much easier.

The Atom AR's high density torso insulation makes the rest of your body nice and warm while cutting down on unnecessary weight in the arms. The athletic cut allows for superb range of motion when using the jacket for climbing, skiing, or even hiking. Ive put it through quite a bit of abuse, from arm jamming in off-width cracks and skiing long days with this baby.

Thankfully Arcteryx made this jacket with active folks like me in mind, and if you are needing a midlayer workhorse for skinning up a ridge, hiking to your local crag, or even just hanging out at the coffee shop, this jacket is for you!

New favorite jacket.

    I have the black and haven't had any trouble with it. Very warm. Looks good for most occasions. Works perfect for me under the beta AR for extremes. I tried the atom lt as well and much preferred this one for warmth and versatility. Xl fit great for me 5'11 205

    Thanks for this review and posting your sizes, Brian. It's so helpful.

    Great jacket, but don't get the black

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

    Great fit, great construction, lovely details. Fits similar to my Patagonia Nano Puff, but is a good deal warmer. Minimal bulk compared to a lot of high loft synthetic and down fill jackets. I'm a big fan. One note: the black attracts dust like no other jacket I've ever had. I live in an older neighborhood and and just brushing against the wall of a house on my way to work and one shoulder was covered in white dust. meant that my shoulder was covered in white dust. I've never had another jacket do this.

    One of my favorite jackets too, super versatile.

    Atom AR

    • Familiarity: I returned this product before using it
    • Fit: Runs large
    • Size Bought: large

    Nice jacket, nice weight and finish. Sleeve ends are finished nicely. I wouldn't say, though, that it's an athletic fit, especially compared to a Mammut or Marmot. There's a good bit of room in the torso and the neck is huge - maybe to accommodate a couple other layers of zipped-neck garments. Fit well in the shoulders but if you've got a significant drop between chest and waist I think you'll find that it's roomier than expected.

    I love this jacket

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

    I love the warmth of this jacket and the small size to which it can be compressed. With only a t-shirt on underneath, I can be outside in sub-freezing temperatures with little to no activity. I definitely recommend it. One comment - this jacket definitely runs small. I am 6'4, 225 lbs and usually take an XL. The XL was comically small. I had to return it for an XXL.

    Great jacket and insulation layer

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

    The Atom AR compliments my Theta AR Shell Jacket as an insulation layer. It also works great around town as an everyday jacket. The fit is perfect allowing room for layers without being bulky. It really does a nice job keeping you warm during cold alpine ski days as the insulation layer.

    My favorite down jacket

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

    The Atom AR is the most versatile jacket I have ever owned. It sheds rain and light precipitation even after a year of abuse, and it's managed to retain it's shape as well (thank Coreloft for that). But my favorite thing is that it regulates temperature so well––wear it with just a t-shirt and it's perfect for anything down to 40F degrees. Throw a light 1/4-zip fleece under it and it's good down to the teens. Put a shell over that combination and you can dip into the negatives with no worries. Basically, there's no weather under 60F degrees where this jacket isn't useful.
    Now a little about the craftsmanship: it's excellently made. The fit is fantastic, leaving just enough room underneath for a fleece (heavy or light, your choice), but it also has a slim fit that layers really well under other jackets. The zippers are a dream, and the handwarmer pockets are "that" detail that make you happy every time you put the jacket on.
    The price might seem slightly steep at first, but you get what you pay for, and as strapped for cash as I am right now, I would have no issues buying another one of these jackets because it's just that good.

    The best jacket I have ever owned

      This jacket exceeded my expectations. It is amazing. It is hands-down the warmest jacket I have ever had. Weight-wise, it is lighter than a hoodie, and literally feels like you are not wearing a jacket at all. The material is very soft, and the arms slide right on without lifting up my shirt sleeves. I love that when the jacket is fully zipped, it completely covers my neck.
      That's the first reason for less than five stars

      Plush and lovely

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

      I've used the Atom AR a handful of times in roughly 48 - 68 degree weather so far and the midlayer performs beautifully--if anything I was a bit warm. I've yet to push it to colder temperatures, but based on how well it kept me warm on its own, I'm confident that with proper layering the Atom AR would do just fine when the mercury plummets as well.

      Atom AR & Atom LT

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

      I have both the Atom AR and the Atom LT. I guess this review points out what I feel are the major differences and some similarities. The Atom AR has more Coreloft insulation, and of course makes the jacket warmer. I use it for trekking or just around town on fairly cold days. Awesome warmth. The AR has an athletic cut, (Arc'teryx's standard fit) so it's not as close-to-skin as a trim cut. I ordered the iron anvil color and was afraid it would be too light of a gray, but is darker than the color swatch. A final thought. Maybe not necessary because it fits a bit looser, but I really like the stretch panels that are part of the Atom LT jacket. More about that in an LT review. Great jacket. Glad I have both for different uses and different temps.
