    Details

    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

    The G.O.A.T.

    • Familiarity: I've put it through the wringer

    This jacket is the GOAT of all mid-layer puffy jackets. Cold office mornings, fall hikes in the mountains, nights out on the town, and a mid layer while skiing, this jacket does it all and absolutely crushes it. I've been a Patagonia puffy wearer for a while but this jacket has made me a convert.

    Versatile mid layer

    • Familiarity: I've put it through the wringer

    Great all around midlayer. Go to layer worn climbing, hiking, mountaineering and arrond town. I have used as outer layer with a t-shirt or poly-pro when moderately active in temperatures ranging from 30F-60F, and as mid layer in bellow freezing temperatures. Breathes very well, resist moderate wind and light rain, and fits like a second skin. Be careful with sharp edges ( rocks, crampons, ski edges, etc) material snags easily... in my experience.

    Love the trim fit. I'm 6',1", 190lbs, 42" chest, 34" waist Levis, athletic built... purchased a Medium. I would recommend you try one on before purchasing... or if ordering on line without having tried one on don't size up-- it would be like sizing a sweat shirt to fit over another sweat shirt,. i originally purchased a Large, based on the reviews which commented on the "smaller fit" and I returned/exchanged it for a M. A Large fit like an outer layer/shell would. A Medium fit as a midyer should IMHO- close to the body with room for a t-shirt/ poly-pro and a thin fleece if necessary.

    My go to jacket

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: Medium
    • Height: 5'8"
    • Weight: 175lbs

    This jacket fits great for someone who works out and is 5'8". Most jackets don't fit my chest or shoulders really well but this jackets fits perfectly. I still use other jackets like the Nano Air to go run in cold temps but the Atom LT fits so well and doesn't bunch up when climbing so its my go to around town and still comfortable and can still perform really well up to 20k in Peru. The range of temps this thing will work in is awesome. I would say 20 to 65 degrees. If it dips below 20 (andI'm not super active) I put on a thin Patagonia Capilene fleece under with a Patagonia Down Sweater over it. It really layers perfectly for me.

    Versatile & Useful

    • Size Bought: Medium
    • Height: 5'11"
    • Weight: 160lbs

    What can I say? I own one with the hood and one without. That's how much I love this jacket. I've used in during winter hikes in Utah and it's warm enough with just a t-shirt underneath or a fleece under it for sitting around the camp fire at night. It's great for outdoor or just everyday use around town. It fits like a glove for me. Highly recommend!

    A must have

    Versatile year-round, you’ll be layering this under your ski jacket in the winter and using it when the sun goes down on cool summer evenings. The Atom LT is designed to stretch to allow full range of motion and is finished with a water-resistant coating.

    The Perfect Midlayer

    From the endless glaciers of Mount Rainier, to the massive granite faces of El Capitan, and the rugged ice clad peaks in the high Sierra the Arc'teryx Atom LT is perhaps the best insulating piece I have ever used. Its functionality is very well thought out, and with high versatility, decent durability, and high comfort it is a true workhorse in any environment. This jacket was designed with the intention of moving fast in the mountains, because of this the jacket is lightly insulated and highly breathable, but also surprisingly warm for how thin it feels. For storage, the jacket can be easily packed into its own sleeve.

    Insulation
    -------------------------------------------------------------------
    The jacket uses 60 grams of Coreloft™ insulation. Composed of polyester, this material is durable, lightweight, dries far more quickly than down, and most importantly will still keep the user warm when wet.

    Fabric
    -------------------------------------------------------------------
    The outer shell of the Atom LT is composed of 20 denier nylon Tyono™ fabric on the majority of the jacket, and a polyester/elastane Polartec® Power Stretch® fabric under the arms and on the sides of the jacket. The Polartec® fabric is extremely breathable, and is quite stretchy. This gives the user better range of motion especially when reaching overhead while climbing. The Tyono™ shell material is DWR treated and is thus highly water resistant. I have walked for miles in light to medium rain in this jacket while remaining completely dry. The same material also makes the jacket exceptionally wind resistant, The interior of the jacket is the same material as the outer with the exception of the underarms which are a soft comfortable fleece.



    Comfort
    -------------------------------------------------------------------
    One of the greatest reasons that I love this jacket, is that it is incredibly comfortable and remains so indefinitely while moving in the mountains. Because of its superb breathability, the jacket has a massive comfortable temperature range. I have worn it from the mid sixties to the low twenties (Fahrenheit) and remained the same comfortable temperature. The hood is also climbing helmet compatible and works well both under and over a helmet. The jacket is also extremely lightweight for the warmth that it provides, and feels almost weightless as you glide across technical terrain with ease. This jacket makes the perfect mid-layer, and when paired with a good base layer and high end hard shell such as the Arc'teryx Alpha SV (review coming soon). It is perfect for almost any conditions in alpine environments weather hiking, climbing, backpacking, or skiing.



    Reliability/Durability
    -------------------------------------------------------------------
    After 6 months of very heavy use in the mountains, the jacket is still in almost perfect condition/ The outer shell is surprisingly resilient for how thin and light it feels, and provides decent protection against abrasion. The jacket did get a small hole after getting snagged on a section of razor sharp rock while climbing in Wyoming, though this was easily repaired with a tiny Goretex patch. Other than that, one of the jacket's cuffs is starting to show signs of wear as a small hole has appeared where the cuff connects to the shell fabric. As far as reliability, this jacket has never failed me even after hundreds of hours in the mountains and in often heinous conditions; rain, snow, sleet, sand, dirt, nothing can stop this jacket from doing its job. When cared for properly and washed with an appropriate technical clothing detergent (Arc'teryx recommends Grangers, but Nikwax works just fine) the jacket remains in very good condition, and the insulation has not lost any loft whatsoever.

    The Perfect Midlayer

    Replacing my first Atom

    • Size Bought: small
    • Height: 5'10"
    • Weight: 155lbs

    I bought my first Atom back in 2010 and have just now (7+years later) decided to buy a new one because it's starting to show it's age a bit. The Atom has been my 'go to' warmth layer for hiking, skiing, and even just walking the dog on a cool morning. The fit is modern and clean, and does not feel bulky. It repels rain and keeps you warm with minimal under layers. Great travel jacket because it packs down light and can handle a wide range of temperatures and weather scenarios. I can't think of a better jacket in this category. I'll probably buy another one in another 8-10 years.

    This is my go to wear. Hiking, climbing, skiing (base layer), biking (early summer, late fall), camp fire, night hikes, cold office and all the fun activities that I can do in SLC, UT.

    You will reach for this layer more often than not. My first Arcteryx piece and fell in love after the first use. It is very light and punches above its weight in warmth but with the mesh side panels is perfect for a bit more active pursuits. I have been using as insulation layer under my snowboard shell and as my puffy on a milder temp backpacking trips. I bought it with split-boarding in mind for next year. It sheds light moisture and is really soft to the touch. Do be careful with board edges, crampons, etc! It does tend to run just a tad trim due to Arcteryx's apline-oriented sizing standard, but I bought the size I would in any other brand.

    Still not a size Large :/

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: Large
    • Height: 5'11"
    • Weight: 155lbs

    I am a true medium in every shirt and jacket, except I usually buy Large in outer layers..... but I should have stuck with the medium because it still fit well in regards to length but was just a little too bulky for my taste.

    However, my dad liked it so much and it fit him perfectly that I had no choice but to give it to him.... and he said some stuff about raising me and blah blah.

    (he's fit but built in his upper body, 6'2", and usually always wears a size large).

    Amazing coat, problem with fit

    • Fit: Runs small
    • Size Bought: Medium

    This coat is without peer in flexibility and warmth for the weight. I ordered a recent model and the upper arm/chest region was more snug than in past models. I am fit, but not overly-buffed. I was looking forward to owning more than one of these coats, but, regrettably, the new fit is not a keeper.

    Great for casual walks in chilly temps

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Large
    • Height: 6'1"
    • Weight: 180lbs

    I love this jacket. I live in Utah and have been using a North Face Thermoball and it's a little to heavy for walking around town unless it's stormy and snowing out. This jacket breaths and is perfect for physical activity when it's not the dead of winter, but also functions well as a mid layer in below freezing temperatures. It is also more fitted and very comfortable.

    Everything you would hope for

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Height: 5'11"
    • Weight: 155lbs

    I don't know if I can add anything that someone hasn't already said. The proof is in the details for this jacket.

    As Advertised

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Small
    • Height: 5'9"
    • Weight: 140lbs

    I thought about buying this jacket for a while, I read reviews, went back and forth over sizing, and finally took the plunge. So far, it's everything it's advertised to be. Its breathable yet warm, fits snug, but not too snug, and feels quality made. Before this purchase I was hesitant about Arc'teryx products, thinking it was just a more expensive brand name, but after this purchase I'll be looking for more of the same. I haven't put it through the wringer yet, but so far I've worn it every day since I got it, and in conditions including rain, sleet, snow, and sunshine. The Atom LT has been comfortable in each. The DWR treatment has water beading off like a slicker, the insulation is in the right areas for the right warmth, and the touch of fleece lined pockets is there to round it off. Great jacket, buy it or be disappointed.

    Love it!

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Medium
    • Height: 5'11"
    • Weight: 175lbs

    It's a great jacket and I have been wearing it almost everyday. I am 5'11, 175 lbs and ordered medium. (Usually order medium for most jackets) Considering It looks a bit tight fit through the mirror but it's surprisingly comfortable and I don't feel any tightness in any particular places. Large size might be better for the look but medium still works great for me since the main reason I bought this is to use it as a mid layer for cold weather. I will probably try a large size next time I purchase other Arcteryx products.

    Super light and comfy!

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: M
    • Height: 5'10"
    • Weight: 165lbs

    I just got my first piece of Arc Teryx, the Atom LT. Instantly I want the whole collection. The fit is insane, craftsmanship is unreal and functionality is stunning. Truly a believer now in the Arc.

    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?

    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.



    If you have anymore questions feel free to send me an email or call!

    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!

    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!

    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?
