    SoCal Weather

    This jacket is great for everyday insulation for various types of weather and I chose this over the Atom AR because I felt it would be more flexible with the warmer temperatures in SoCal. I must admit though I was expecting it to be warmer for colder climates when I went to the mountains that reached to ~28 degrees Fahrenheit - I had to wear a warm fleece to keep myself comfortable. But for regular outings like camping, climbing, or just out in the town there is no better jacket out there!

    Great jacket.

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

    I’ve only used this jacket for everyday use and walking around town. It’s been cool to cold and very rainy. The jacket has kept me warm and dry. The hood fits very comfortably over a hat and helps keep rain off of my glasses and out of my eyes. I’m know expert, but a close friend recommended this jacket to me and I have been very pleased. I was also pleased with the offer at Backcountry. The fit is perfect and the jacket was delivered on time.

    My new go to insulation layer!

    I don't know what I can say that others haven't already. This jacket is fantastic, I was coming from an older mountain hardwear thermostatic jacket which was alright. The fit of this jacket is superb, the pockets are better and I like having the hood! The thing I was most impressed with this jacket was moisture management. I sweat...like a lot...and in 4 days skiing between high teens to low 30's this jacket functioned as my main insulating layer. Regardless of how much I sweat, I stayed very warm, and felt dry and I attribute that mostly to this jacket. I was amazed at how quickly this jacket would dry out after a day on the slopes, I could shower and dress for the evening and it was dry by the time I was ready to walk out the door! And best of all, it didn't get funky and hold onto smells like some synthetics seem to.

    All in all, don't hesitate to purchase this jacket, it truly is a do everything insulation piece which could be used as a mid layer or to wear out in the evening!

    Tremendous, just be wary of sizing!

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

    I'm 6'0 170 lbs with a slim/athletic build. I purchased a size large in Oxblood Red. I purchased a size large because of this jacket's supposed 'trim' fit and because I intended on wearing a fleece mid- layer underneath. First and foremost, the look, quality, and comfort of this jacket are all incredible. Upon first trying it on, it instantly became my new favorite jacket. Now to the sizing issues...For the most part, the jacket fit rather well in the torso/chest region. However, the jacket ran a bit long, and the waist hem was a bit wide/baggy for me. Sure, I could use the drawstring to adjust the waist hem, but it just doesn't look so great when wearing the jacket. Ultimately, I am going to say the jacket fits 'true to size', although I will personally note that it is trim in the torso, wider through the stomach/waist, and is cut long. I intend on returning the jacket for a size medium, but now I am nervous that this new size will be too small...wish me luck!

    Fits and looks great!

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

    I was searching for a multipurpose jacket with all the features this one has and I wanted a trim, athletic fit. This one fits perfectly and looks very nice while seeming to be very warm!

    Versatile

      I wear this jacket more than any other that I own because it is so versatile. It vents body heat when I'm active on an approach or multi-pitch climb and keeps me warm when I'm standing still. I'm 5'9", 150lbs and wear a size S.

      Good, but re-work the drawstring!

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

      Brought this with me as a midlayer during a very rainy and cold Mt. Fuji trip. It fit well under my Large Patagonia Super Pluma Gore



      I am a 6'2" 200lb man and opted for the large, which fits perfectly (exactly as seen on the dude in the stock photo)



      Packability is decent when you stuff the coat into it's sleeve (it does not stuff into a pocket or a stuffsack). Obviously, down packs better, but it'll squeeze into a 10" by 5" oval without much trouble.



      My only caveat is the drawstring that pokes into my right hip. It seems to be larger and bulkier than other drawstrings and would leave a bruise if bumped against a tree on the trail.

      Good, but re-work the drawstring!

      Really great jacket

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

      I've had it for over a year now and can easily say it's my favorite jacket I've ever owned. It's on me every day whether going to work, camping, skiing (probably its best use), climbing. I hung it in the closet from June through August but now its back on me every day. My favorite part about this jacket is it feels like you're wearing nothing; it's so light and so easy to maneuver in it but still so warm... It's really a perfect jacket, especially if you run hot, you can get away with wearing this in pretty cold temps.

      Nice light weight insulated jacket that adds the right amount of warmth and protection. Use it with just a t-shirt on crisp New England fall days, throw it on under my shell on snowy cold ski days and could not be happier. Really seems to always have the Goldilocks balance, not too hot, not too cold, just right. Got it off SAC for a great deal, if something was to happen to it I would repurchase for full price though, it is that much of a go to.

      Switching up a layering system is always an adventure. Got this jacket through my guiding outfit. Though its light on the insulation, this jacket really is fantastic for moderately cold days, or cold days and high output activities. The shell lightly repels moisture and the insulation doesnt seem to get bogged down when it gets a little wet. On ultra cold sub zero days I was able to wear this under a shell while ski touring without overheating. The jacket does a great job of dissipating heat. It packs into its own pocket and is super light. The hood is pretty amazing too. I had good luck fitting this under or over a helmet! Bonus! Pockets where you want them and just the right size. This jacket is function meets form. Couldn't be happier, but not my go to for lower output activities in the frigid cold.

      Great cold/rainy day jacket

      Couldn't agree more with what has been said about the Arc'Teryx Atom LT Hooded Insulated Jacket. This jacket is one of the pieces I use most when outdoors. It is light, warm and breathes well when exercising heats up your body. Synthetic insulation means it performs well when wet or when I get sweaty. My most common uses are for fall hikes or as a mid-layer in winter while snowboarding. This is a must-own jacket

      Has anyone had any problems with the zipper? I haven't worn it yet but just pulling the jacket open when it's half zipped, tends to unzip really easy.

      Just concerned of it unzipping easily while doing things.

      My heigh is 5'5", should I go for the xs or small one? I also wanted to know how long is the jacket (is it hip length or like in the mid thigh)?

      Unsure about what size I should get...I am 6'0 170lbs with a slim/athletic build. I want to be able to wear a fleece jacket underneath this, so I was thinking a large, but I am not sure...

      I'm built similar to you (6'1" 175lbs) and sport a medium in this jacket and would not be able to fit a light 100wt fleece under this comfortably. You would probably be better suited with a large if heavy layering will be used. It's a tad slimmer than say a similar Patagonia sized jacket, but works great with a long sleeve shirt or thermal. I love this jacket for it's weight to warmth ratio you will not be disappointed...

      How well does the hood fit when not wearing a helmet?

      Hey Matthew, I've never worn a helmet with mine and have had no issues with the hood. I do not own the newest version of the Atom LT, so my hood doesn't even have any adjustments. Considering my experience and how you can now adjust the hood, I'm confident you won't have any problems.

      I am trying to decide between the hood or no hood. Definitely plan to use it under my shell for skiing which is where the hood could be annoying. But for other things where I use it as an outer layer (belaying mostly and/or hiking) the hood may be nice. Is the hood annoying under a coat or is it not too bad?

      Hi, I'm 181 cm / 73kg / 95 cm chest.

      Would you recommend a Medium or a Small?

      The chest measurement is the best to go off of when picking out jackets. The small will actually be a perfect fit for you if you want to wear the jacket the way it was intended to be worn which is athletic or slightly tighter for people climbing in it. If you want a much more relaxed fit then the medium is an option but, I feel that it would be way to big as the small chest measurement fits best for people at 97cm.

      Is there a jacket similar to this but more waterproof? Open to other brands. thanks!

      With the DWR treatment this tends to shed rain about as well as a softshell. If you're looking for full waterproofing you'll probably want to look to a hardshell. If you're looking for light versatile layers I like the Patagonia Alpine Houdini as something to get on quick when the wet gets insistent.

      I am 5'10 and 175 with an athletic build - what size would you recommend? Thanks!

      How would you compare the warmth of this jacket to that of Mountain Hardwear Ghost Whisperer or another similar down jacket?

      Best Answer

      I think my Ghost Whisperer might be slightly warmer than my Atom.

      The warmth of any down jacket is going to be directly related to the loft. Thicker = Warmer. Note - Fill Power is a measure of how light and packable the down is. This is where the Ghost Whisperer blows most jackets out of the water.

      The atom still has an advantage in a lot of areas, however. It's more comfortable, I like the way it breathes better, I like the hood better, it's more abrasion resistant and it moves better. It's also going to do better in wet weather being that it's a synthetic. The Ghost Whisperer is still going to win in the lightweight and packable categories however so if that's your priority, then the ghost whisperer may be the way to go.

      The atom is probably the best jacket for 85% of situations and a favorite of a lot of people I've worked with over the years in this industry. I think everyone should have (at least) one.

      Why is "rusted copper" a shade of orange? Shouldn't it be a shade of green? Just sayin'.

      So I am debating between the S and M i am 5' 7-8" and 145-150lbs i want to be able to add a layer like a hoody underneath so i don't know if the small would be to tight but i don't want the medium to be to baggy if i wasn't wearing a hoody under it. so not really sure what size to get any help is appreciated thanks!

      Hello,

      At the moment I'm looking for a super versatile, do it all, tough jacket that I can rely on in a multitude of conditions. I've narrowed it down between the Patagonia Nano-Air Hooded vs. this Arc'Teryx Atom LT Hoody. Could someone give me a breakdown on the pros and cons between these two jackets? I'm trying to find as much info as possible so I can make the right decision when purchasing my next jacket. I've only found one article online that discusses these two jackets exclusively, so if anyone can help me out, that'd be great! Thank you very much!

      Hey Jane Hwang.

      The man in the photo... what size he is wearing? And what is his height?

      I see that the LT is Hood compatible. If worn without a helmet is the hood too large on your head. I would like to use this jacket without a helmet for hiking.

      Also, is this jacket a 2014 version and does the hood and waist have draw strings ?



      Aside from the LT being warmer how would you compare the LT to Outdoor Research Cathode Hooded jacket ?

      How well does this hold up as an outer layer? Looking for a swiss army knife type jacket... Lightweight/Compressible, Insulated, Water Resistant/Proof... Hoping this might be the right piece. Love Arc'teryx gear in general. Thanks for any advice on it.

      Best Answer

      Hey! Jacket definitely is water resistant but, not proof. I would also question the durability of this jacket on the mountain as an outer layer. As a around town jacket it is just fine, I would even wear it touring on the up but, on the down snagging trees and what not you really need a hard shell or at least the burlier version of this jacket in the AR version, http://www.backcountry.com/arcteryx-atom-ar-hooded-insulated-jacket-mens?ti=UExQIENhdDpNZW4ncyBTeW50aGV0aWMgSW5zdWxhdGlvbiBKYWNrZXRzOjE6MzpiY3NDYXQxMTEwMDE2&skid=ARC004D-BK-S

      Does anyone know what is the main difference between atom leaf vs ordinary model?

      Does leaf atom model have 40d fabric?

      How does it compare in general to ordinary atom?

      The main differences between the leaf model and the regular one are that the leaf has a more durable face fabric (called Gossamera--same fabric as the Atom AR), it is a few ounces heavier, has a "vertically routed" hip adjustment cord, and the color of the logo matches the fabric color. In my experience, the leaf model fits a little baggier. I ended up going with the regular model because it fits a little trimmer and is more packable, which is what I was looking for.

      I bought an Atom LT hoody about a year ago on BackCountry. I love everything about this jacket except for one major issue. The main front zipper will not stay all the way up when doing almost any sort of activity. It literally falls down 4-5 inches even when just wearing a backpack. I talked to Arcteryx with no resolve and was told it was by design to make one hand operation easy. My question is have they fixed this design issue for the new model this year? I love my jacket but this zipper issue is a tough one to overlook, just wish I could somehow get it resolved from a company like Arcteryx........

      I asked my buddy who used to work at Arc'teryx and he also says that the zipper is like that by design for easy one hand operation.



      For instance, when you have a shell on and want easy access to some ventilation, you can unzip your shell and pull on the collar of the Atom LT to open it up some. While the zipper is soft, I have one myself and haven't had problems with it unzipping too much.



      So to answer your question, no, they haven't fixed this--but they also don't see it as an issue since it was designed this way. Still love this jacket!

      Hi!



      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.



      Thanks!

      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?
