All weather beast

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

If you are looking for an all weather jacket that performs when the sun is out or the storm's are headstrong this is the jacket for you. Arcteryx is already a name many adventurers turn to when they need reliable gear. This jacket is burly, well insulated, and surprisingly compactable when not in use. Normally I am a medium but I went with the Large because it allows me to layer ( the only reason I would need to layer would be for those sub zero temps). Look no further.


My Everyday Winter Jacket

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

I'm 5'11", 165 lbs and this jacket fits nicely, hitting around mid-hip. It is also a little roomy inside to make layering easy without feeling baggy or bulky. The material is very soft and cozy, the stretchy cuffs are really nice and solid, and the hood is phenomenal. This jacket holds up to almost anything the Boston winter has given me and works great to warm me up when I get cold on a climbing or skiing trip. I've worn it almost every day both this winter and last. For light precip, it holds up very well and stays dry and only gets slightly damp on the outside in slightly wetter conditions (while staying dry inside).

My favorite feature is the hood, which cinches down very easily and is extremely warm and comfortable. If I get chilly, putting up my hood always gets me warm quickly. In 20 deg F weather, I'll feel perfectly comfortable with the hood up, even if I just have a T-shirt on underneath. The jacket breathes decently well and will not overheat in mild to moderate activity. There's also soft, comfortable fleece lining the hood/mouth and armpits, which help with this too. However, you will get hot and sweaty fast if you get too active in this jacket.

This has become my favorite everyday cold weather jacket. The Saguaro green also looks awesome! Get lots of compliments on it.


Sleeping Bag Jacket

Love this thing. Very warm and feels like you are wearing a sleeping bag. I ordered the Storm color and it has a bit of purple in it. I like the color better than just a gray. Fit is true to size...

My mistake I order size l it wrong size...

My mistake I order size l it wrong size it to big but backcountry didn't have size m how can I do pls let me known thank you

Hey Jeraboon,

Below is a link for our full return policy. However, if you are looking to do an exchange we still do not have a size medium in stock to do so.

Return it and buy the Atom AR, also available from Backcountry. Apparently the Arcteryx company has stopped production of the Atom SV. The Atom Ar is a slightly trimmer fit and is only 20 grams lighter (less than an ounce), so the warmth will be very similar. If you're not climbing or otherwise wearing a helmet or another jacket from Arcteryx with a storm hood you might also consider getting the Atom AR without the hood and go with a good knit/poly hat. I like the one put out by Arcteryx, in fact have two. I don't climb too much any more at 70 but I still go high in the mountains to trek around.

Go to and type in atom sv hoody. They have all sizes and most colors...


Jack of all jackets

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

I love my Atom SV. This jacket is warm enough to wear alone during most SLC or Denver winter days and nights. Black looks classy enough to wear out on the town, without looking like a sno-bro. My only qualms would be that; It is a little much to use as a mid layer during a tour, which is partly due to the lack of pit zippers or any venting. That being said, I will be buying a more active mid-layer jacket. All in all, I love this coat more than any article of clothing ever.

I am 6'1 and 182 lbs, I would like to use...

I am 6'1 and 182 lbs, I would like to use it as an outer jacket for some skiing with some layering, but also use it as midlayer under my Patagonia Triolet Shell on bad conditions. Should I go for a Medium? or Large? I think could be better a Large for me.

Thanks in advance.

Best Answer

Patricio, it sounds like you need a size large but I'd double check your measurements on the Sizing Chart to be sure.

Patricio, I'm about your same build, Arc'teryx Large fits me very well. This jacket is a trimer fit to be worn as a layer and not an outer layer.

Nice, same fabric and hood or changing things up like the Atom lt?

Atom Lt will use Tinthan face fabric and the Atom AR is the same Gossemera fabric of the atom SV

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.

Nice solid warm layer

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

I was worried a bit about sizing, as I'm normally a medium in Arc'Teryx softshells, but I tried on a large and found it fit me better (5'10", 155lbs). I have a slightly long torso, and knew I would almost always be wearing some kind of layers underneath as well. It's tailored very well so that with the bit of extra size, it doesn't feel or look bulky at all. That all being said, it IS closer to true size.

The soft stretchy cuffs are great--very comfortable. I haven't had a chance to get it wet yet (and of course wouldn't want to face a downpour in just this), but if the finish is similar to my other Arc'Teryx jackets, it should be no problem in a quick sprinkle.


My Favorite Insulated Piece

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

I've owned the Atom LT Jacket for a few years and really like the quality and design, but I found that the LT wasn't holding up to the close to zero degree temperatures in Virginia this past winter. That said, once the temps hit rock bottom I decided to purchase the Atom SV for more substantial insulation and the added bonus of a hood. The result was adding a piece to my gear collection that became my all around favorite winter jacket. Regarding the fit, I greatly prefer the cut of the SV over that of the LT. The LT is meant to be an insulated layer, generally worn underneath a hard or soft shell, while the SV functions more as a stand alone piece. Consequently, the SV is longer in length and more full throughout the body, but not so much that it sacrifices any of its insulating properties. As for the durability, so far I've worn the SV in every type of winter weather. It kept me warm and dry in snow, sleet, freezing rain, and the occasional "wintery mix," all without needing to put on a hard shell for added protection. The exterior of the jacket is similar to a ripstop fabric, and has been treated with DWR to help repel water and moisture. The result is that the SV never became soaked or saturated in any of the aforementioned conditions. The inside of the jacket is comfortable and it feels great even against bare skin. As anticipated, Arc'teryx paid close attention to detail and lined high wear areas like the armpits and zippered pockets with soft fleece. Overall, I love the feel of the SV when I'm wearing it. In addition to the excellent design inside and out, the jacket is extremely lightweight considering the warmth it provides and doesn't ever feel bulky or cumbersome. It can't be as easily compressed as the LT, but I never found myself in a winter clime where the SV wasn't my jacket of choice. It is certainly the one piece I would chose for the vast majority of winter adventures.


Perfect synthetic insulator

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

I had a fleece that I had to return due to excessive pilling and to their credit Arc'teryx offered to replace the fleece with another item of my choice. I hadn't expected this (as I thought they would just send me a replacement fleece) but I'm extremely happy they send me the Atom SV .

I can't imagine using this as a mid layer, but as an outer jacket it is fantastic. The fit is great with superb cuffs, dropped hem, and an incredibly comfortable hood. The hood adjustments really make this thing bomber when it gets seriously cold or when there is a high wind chill factor.

I am 184cm, 72Kg (6.1/160) and the Medium fits me great. The Atom SV is sized so that you can layer it over some mid layers, which for me at this size it does great. I bought a Medium Atom LT because I liked the SV so much and it fits perfectly under it. A thick fleece or thin down sweater will also easily work. If you want to layer over a thicker down jacket you might want to get a bigger size in order not to compress the thicker down baffles as much.

If you need a synthetic insulator piece with a super comfortable hood, great cuffs and overall fit, this piece is absolutely fantastic and you can't go wrong with it.

i'm 5'8" 150 pounds usually buy size medium...

i'm 5'8" 150 pounds usually buy size medium jackets should i get a small or medium. from some of the reviews I'm leaning towards a small.


That all depends on how you intend to use the Arc'teryx Atom SV. If you want this to be a versatile insulating piece that you can fit under your ski shell or layer under to use as an outer jacket, I would definitely recommend a medium.

If however you know that this will only be a midlayer for you with little layering underneath the small could fit just fine.

The Atom SV is an "athletic" fit. So it is tailored, though not as snug as Arc'teryx's "trim" fit. Personally I would recommend the medium for you based on your height and weight. Though again, I would ultimately consider your intended use when choosing between the two sizes.

I would snag the Small. I am 5' 10" 150lbs, and a small fits me great. It is cut a bit bigger than the Atom LT so layering over a shell is not a problem. It could only be worn as a mid layer on the coldest of days anyway.

I would definitely get a Small. I'm 6.1/160 and have a Medium that I think fits perfectly. I have an Atom LT in Medium too and that one fits perfectly worn underneath the SV.

Just to be clear, the Atom SV is cut bigger, to be worn over the Atom LT. Great combination together. I think you would be fine with a Small to layer it over a mid weight fleece, or an Atom LT, or a light thin down sweater. If you want to layer over a thicker down jacket I might get a bigger size in order not to compress it.


Exactly as I had hoped

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

So far, I am loving my Atom SV Hooded Jacket. I was looking for a while to find an upgrade to my Marmot Primaloft jacket (circa 2000). And with a move from NJ to southern VT, I wanted something that would be a bit warmer. My first week in VT was the coldest week in more than 5 years, and the Atom SV was up to the task. I can see that it may be too warm for some when doing active pursuits (skiing, snowshoeing, etc), but it is perfect as a casual, around the town jacket. Next season, I will try it skiing, matched with my Arc'teryx Theta AR Jacket (I have had several Arc'teryx jackets and have been a huge fan of their quality and how they stand by their quality).


Best synthetic

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

This thing rocks! Coreloft is in my opinion the all around best insulation out there. The clo at 100 grams is 3.38 and yet they never say anything about it. That is a class company for you. The outer face fabric is more durable and more breathable than pertex as well.

Can someone tell me eh zipper length of...

Can someone tell me eh zipper length of this in a large and medium? How does the length and fit compare to the Arcteryx Hyllus? Thanks for the help

My Medium Atom SV has a front zipper that measures a hair over 27.5" long. my hyllus in medium measures just over 26.5" long. Some of the extra length on the ATOM is the higher collar. The Atom will come a little bit lower in the front if I put them over top of each other (crazy warm combo that is totally not necessary). I find the ATOM SV is more versatile than my hyllus. Sadly the ATOM SV is being replaced by the ATOM AR this fall


Comfortable, warm

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

Very comfortable, warm for light weight, hood fits well (no helmet), room to layer under it if colder.


Deceptively Warm!

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

A great warm jacket! Very light but very insulating outer layer.

Purchased the M in storm and fits great. It is not bulky at all and has plenty of room for layering.

Any Idea when there will be a restock of...

Any Idea when there will be a restock of the buckeye color in size small? Not completely happy with the purple hues in the storm color.

Unfortunately there are no plans to restock the small/buckeye in the Arc'teryx Atom SV Hooded Insulated Jacket at the moment (no orders placed with Arc'teryx yet).

However, January and February are big restocking months for us and there is definitely a possibility we will get that color and size back in. Please check back with us in a couple of weeks if you haven't found an alternative source by then.


Great so far but eh

  • Fit:True to size

Light and comfortable, arrived yesterday and wore it to work today, it was 15F here today and it kept me comfortable warm.

Negative is i purchased the "Storm" color and the zippers and stretch portions appear to be very purple colored.
