    Never leave home without it.

    Who needs a multi-tool when you've got the Arc'teryx Men's Atom LT Hooded Insulated Jacket? Well, you don't—though, you might want to bring one along anyway (just in case). More specifically, the designers over at Arc'teryx made the Atom LT versatile enough to handle year-round mountain adventures ranging from climbing to skiing.

    The Atom LT is constructed with a durable, breathable, and lightweight Tyono exterior, while the DWR treatment fends off light rainfall—meaning you stay relatively dry no matter what Mother Nature throws your way. To bolster its adaptability, the Atom LT is equipped with gusseted underarms and Polartec Power Stretch side panels to ensure an unimpeded range of motion whether you're wearing it as a midlayer or an external shell. Perhaps most importantly, though, is the Atom LT's synthetic Coreloft insulation. This synthetic insulation not only retains warmth in wet weather, but also offers maximum thermal efficiency without compromising the compressibility of the fibers. A StormHood slides over helmets with ease, and the adjustable hem provides a personalized, snug fit should you desire it.

    • A versatile, highly adaptive jacket for all aerobic activities
    • Tyono exterior is durable and wind-resistant for protection
    • DWR treatment sheds light moisture easily
    • Coreloft insulation keeps you warm even when wet
    • Stretch side panels promote unobstructed mobility
    • Articulated elbows and gusseted underarm bolster comfort
    • Helmet-compatible hood is insulated for added warmth
    • Adjustable hem provides a personalized fit and feel

    New Favorite Jacket

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: Medium
    • Height: 6'0"
    • Weight: 185lbs

    This was my first Arc’teryx product so i had high expectations with the price tag. Was not dsappointed. This is a great everyday jacket that looks really good. Seems like a jack of all trades, master of none type of jacket. Isnt the warmest, lightest, or most weatherproof jacket but it packs a good combination of all.

    The best jacket on the planet...period

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: Medium
    • Height: 5'7"
    • Weight: 135lbs

    This is the most versatile jacket you will ever find. I have had mine for about 3 years and have used it year round from the frozen tundra of Minnesota to the Mountains of Utah and all over the desert in the southwest. Works great on its own or as a midlayer. Water resistant and sheds light precip. Dries super fast if you end up getting wetter than anticipated. Breathes well during high aerobic activity so you stay dry and don't sweat. Insulates when you're being less active. In cooler temps, I pair it with a vest and am good to go. It also compresses down nice and small for easy packing. True to Arc'teryx sizing. It fits slim, I could have gone with a small but I prefer a little looser fit so I chose medium.

    Everyone should own an Atom LT

    • Size Bought: Large
    • Height: 6'0"
    • Weight: 200lbs

    Don't think too much on the LT. i have been touring in this jacket all winter and it keeps me plenty warm. i have been out in the 0 degree temps touring up the mountain and my fingers are cold before my body. its got the Polartec Power Stretch with Hardface Technology under the arms that allows some breath-ability.I wear this out to eat, to work, touring, base layer in the resort... its a must have.

    Great performance, but STINKS

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

    Great fit, ultra light and packable, and warm, as per other reviews. However be advised it gets stinky REAL quick. One or two days on the mountain is sufficient to require a wash, or a couple days walking a lot in the city. I've found the best way to remove odor is to wash according to manufacturer's instructions except adding about 1/2 cup vinegar in a pre-rinse, followed by baking soda in the normal wash. This would be a 5 star product in my opinion, if not for the hassle of always needing to be washed.

    In all fairness to Arc'teryx, this is a complaint with synthetic clothing in general. It's about our body bacteria, not the jacket per se, although the bacteria apparently love some fabrics better than others. Here is an NPR story that gives some info and related links: https://www.npr.org/sections/health-shots/2014/09/05/346055067/stinky-t-shirt-bacteria-love-polyester-in-a-special-way.

    Favorite Mid-Layer Synthetic Jacket

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: Medium
    • Height: 5'10"
    • Weight: 175lbs

    I love everything about this jacket. 60g of Coreloft insulation is perfect for a wide variety of activities. The fit and design are spot on and the styling is ideal for technical and casual pursuits a like. I wear it backpacking, climbing, splitboarding and out to the bar. In fact, there are few times when I'm not wearing it.

    My go-to, do it all layering piece

    Somewhat unexpectedly I was gifted this layer, Being a geek for gear I Immediately started seeing what It could do. the most striking features right off the bat were the unbelievable DWR finish that beaded snow and light rain and even worked in heavier rain events rushing out of a crag or between classes. The next most noticeable feature was the hood with a helmet wearer in mind. Often times I see "helmet compatible" hoods that fit a helmet, but doubles as a neck brace. The Atom LT actually makes it comfortable to wear a helmet and a hood which was a welcome surprise. The jacket works best above or around the 30 degree Fahrenheit mark especially when its dry when you're moving around. Below that you definitely need to be exerting a lot of energy but the atom was definitely designed for it. I love the tapered athletic fit body and shoulders because it is stylish and sleek stand alone, and it also fits perfectly below other layers which is a must for colder weather or activities that require you to be stopped for a long period of time. The Atom's performance is definitely mitigated by strong wing where a strong breeze will cut right through the underarm fleece panels, but is easily avoided by an additional layer or a hard shell jacket. In conclusion, this jacket is great for helmet wearing folks and high output activity, but it also works great for a mid layer in colder conditions or foul weather

    Arcteryx sizing has changed

    • Size Bought: XL and Large
    • Height: 6'3"
    • Weight: 185lbs

    I used to love Arcteryx because it had a more European fit, and for someone with my build it fit perfectly. I'm 6' 3", 185 lbs with long arms, and I could consistently buy Arcteryx XL and have a perfect trim fit. Now, Arcteryx has gone the way of Patagonia, sizing larger and larger for American chub on the waist. Now almost anything in XL fits in the shoulders and arms but is baggy and sloppy in the torso. If I order Large the sleeves are too short and the waistline rides too high. Therefore I pretty much can't buy Arcteryx anymore. Bummer because I have loved and worn the brand for a long time. I ordered this jacket in both sizes and neither fit.

    Sad commentary on the (lack of) fitness of so many Americans. What are clothing manufacturers to do? I'm guessing it's too expensive to offer not only size but "slim, regular, overweight" versions.

    gateway arcteryx

    • Size Bought: Medium

    This is my favorite go to jacket to wear by itself in spring/fall conditions, and has just enough water proofness that I'm fine wearing it in light rain. The hood will fit and stay secure over a helmet, but prob won't cover the front third of it. It's so comfortable I have to resist wearing it around the house. :P

    I've used it as an under layer for boarding in the winter from -5 to 35, and I've never felt too warm or too cold. It has no vent pits, which I was worried at first, but I've never had an issue with it breathing, presumably through the stretchy material on the sides. For light cardio activities, I've used it by itself for snowshoeing / winter work outs and it did awesome.

    I'm not normally a fan of cinched wrists and waists on jackets, but this one works to help keep it out of the way and keep you warm. It's slim enough that I can use it for recreational rowing (sculling/sweeping) in the winter months in the PNW, and I can verify that the synthetic will keep you warm even when completely soaked after being dumped in the lake in the middle of winter.

    Oh and about color -- I chose the nighthawk color because on the website and from the name it looks like a dark grey/charcoal. For the uninitiated, this nighthawk hoody is more of a shade of blue.

    If there are drawbacks, it prob be:
    1) it oddly does tend to absorb food smells quite a bit.. not sure if this true with most synthetics but I avoid wearing this into smokey restaurants.
    2) it will make you poor, because after this you'll want to update all your gear to arcteryx

    Arc'teryx – Men's Atom LT Hoody

    This trim hybrid hoody is designed as an active-use insulation layer, providing vital core warmth with liberal mobility and breathability. Lightweight and compressible, the Atom LT Hoody features Coreloft™ insulation in the torso, arms and hood. The side panels and underarms feature Polartec® Power Stretch® with Hardface® Technology, delivering stretch mobility and breathability. A wind and moisture resistant outer shell extends stand-alone usability. Fact: Every person at Head Office owns at least one Atom LT; most of the women have two.

    The reason: Coreloft™ insulation inside a light taffeta shell. All the comfort of a sleeping bag, but it feels weightless.

    Great Jacket

    • Size Bought: XL
    • Height: 6'1"
    • Weight: 225lbs

    The Atom LT is a great all-around jacket! When I first purchased this jacket I was a little bit concerned about how thin the fabric was but it has proven to be very durable.

    Hands down the best jacket I ever owned

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: MEDIUM
    • Height: 5'8"
    • Weight: 170lbs

    I used to always wonder why these jackets are so expensive. I just couldn't justify spending that much money on a jacket, but then I tried one on outside. One word, breathability. When I was outside in the cold, it was a comfortable temperature (not too cold, not too hot). Then when I came inside, I didn't feel the need to take it off right away like most down jackets cause they get really hot. It was still perfect. Bought one the next day.

    Good jacket

      I’ve had this jacket on my wishlist for awhile now, and when REI put it on sale I jumped on it. I tried on a medium and it fit my torso and the length of my arms well, but was constructing in my armpits. The large is a bit baggier through my torso, but fits better on torso length and isn’t constricting through my armpits and leaves room to layer under should I feel the need. For reference I’m 5’10” 175# and athletically built. Overall I’m excited to get this jacket out on the trail during the shoulder season as an alternative to my puffy.

      The best synthetic jacket out there

      • Familiarity: I've used it several times
      • Fit: True to size
      • Size Bought: Large
      • Height: 6'4"
      • Weight: 160lbs

      What can I say about this jacket that hasn't already been said! It's an amazing piece of gear, it keeps you warm, but breathes incredibly well. It's easily the most versatile jacket I own. I also have the Cerium LT, which I love for it's warmth and compressibility, but it's not nearly as versatile as the Atom. I know I'll be wearing it for years to come!

      I'm 6'4", around 160lbs and I bought size Large. It fits great, body is a little big on me but that is to be expected since I'm tall and skinny. I have Large in the Cerium as well and it fits the same!

      The best lightweight breathable jacket

      • Familiarity: I've put it through the wringer
      • Size Bought: Medium
      • Height: 6'1"
      • Weight: 150lbs

      I have the atom AR which is a little heavier and I've loved it for years but when I got the LT i was skeptical that it would be too thin or breath too well. To my surprise it keeps you really warm but once you get warm it really breaths well. Great for touring, hiking or just around town. You will not be disappointed.

      Best piece of gear I own

      • Fit: True to size
      • Size Bought: Medium
      • Height: 5'8"
      • Weight: 170lbs

      The jacket is very versatile. I wear this jacket nearly every day around town, and I've worn this in the 60s and down to the low 20s with only a t-shirt underneath. It's super soft and light - it's like wearing your fluffy sleeping bag. This jacket fits very well, and the elastic cuff is really convenient. You can't go wrong with this jacket.

      Buy it already

      • Familiarity: I've used it several times
      • Fit: True to size
      • Size Bought: Large
      • Height: 6'2"
      • Weight: 200lbs

      This is the most versatile jacket I have had. You can literally wear to anywhere and do anything. I had my eyes on the Atom LT for a few months and wish I got it a lot sooner.

      Perfect

      • Familiarity: I've put it through the wringer
      • Fit: True to size
      • Size Bought: M
      • Height: 5'10"
      • Weight: 150lbs

      This is my go to jacket for everything! Perfect warmth for typical winter temperatures. The main zipper unzips very easily by just pulling apart the two sides which makes taking it off and putting it on a breeze. Great jacket and awesome dark blue color

      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.

      It's designed to be easily opened using one hand, without the other having to hold the other side. I know what you mean, but I really like how smoothly it opens. It shouldn't be sliding down on it's own, though.

      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...

      I agree with Philip, go Large in the Atom LT if you want to layer a fleece underneath. I am 6'1" 185 lbs and have this jacket in Large so feel free to shoot me any additional questions directly.

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

      Best Answer

      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?

      Best Answer

      I have the hooded version and use it as a midlayer under my shell for skiing, it doesn't bother me. I can tuck the hood into the shell hood and I don't even notice it. The hood is definitely worth having, especially on a cold night to keep your head and face warm.

      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?

      Hey Samer

      My brothers height is 5'9" and he is wearing a size medium. I hope that this helps and if you need more help please feel free to call or chat into our customer service center and we can get you squared away!

      Cheers!

      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 ?

      Best Answer

      becks4312304945,



      I can't speak to the comparison between the Cathode and the Atom LT, but this is the 2014 version with the hood and waist cinch cords. Even without the hood tightened down, it's not offensively big when worn without a helmet.

      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!
