All I can say is that mine was a layer for 12 days between basecamp and the summit of Aconcagua, and it was an indispensable piece of lightweight gear. If it can help keep me warm at 20,000+ feet, it's good for lower altitudes and less demanding conditions. Worth it's weight in gold. I like it so much, I have the hooded and the un-hooded versions.

Hi There- I'm tossing up between Med and Small. I'm 5'10, 153lb, athletic (as in cyclist..). I do prefer a snugger fit, so leaning small, but I'm concerned the jacket will ride too high, and my wrists will be chilly. I wear 30" trousers. chest is probably 37-38ish.. THANKS!

I'd definitely go with the Medium. You're almost the exact same size as me and a Medium fits me in almost every brand. I'd worry about a Small being too short/tight.

I bought this jacket in 2009 and it remains one of my favorites. It feels great over a wide range of temperatures, say, down to the 20's (if you're active) and up into the 60's. It's light (my medium weighs 12.3 oz) and the trim fit looks great around town AND on the trail. The "Powerstretch panels" do a nice job with ventilation during exertion. Jacket does have an internal chest pocket which is not listed in Product Description above. There's no cinch at the waist hem, but it's stretchy and wind-up-my-back hasn't been a problem. I'm a big fan of the "stretch-knit cuffs" - Arc'teryx chose a sweet fabric and nifty design for this part of the jacket (and the cuffs just feel great on my wrists). I can't recommend this jacket enough.

I've owned this jacket just over a year. I wear it everyday from October -March. It is the perfect piece for cold commuting on a bicycle and chilly days to the craig.
I was very skeptical of the Coreloft insulation before I had purchased the jacket, and now I am a believer. It regulates with your body temperature very well. Not quite as good as premium down, but it still works amazingly.
Thinking back on it, I wish I would have gotten the hooded version, but this piece is very nice, but it also passes for looking like casual jacket.
Don't get me wrong, I'm a huge gear whore, but I don't feel the need to have every jacket look like I'm geared up to Summit K2 when I'm going out to dinner.
For sizing, I'm a pretty thin guy. 6'0, 135lbs with an even ape index. And I think it fits very nicely. It's hard to find a medium that actually fits these days.
The only thing I would add would be elastic waist tensioner so the bottom was more form fitting to my actual waist.

When I first received this jacket, I was a little disappointed by the lack of , well, jacket. It's a very thin jacket. For it's price you would expect something like the Patagonia Down Sweater, which has substantially more girth.

But, after putting it to use, I am absolutely pleased with my purchase. For being a thin, slim fitting jacket, it is VERY warm. I use it as my insulating piece beneath an Arcteryx Theta SV, and the combination is perfect. It does a great job on colder days when temps are below freezing, although if the sun is out, and temps begin to climb at or slightly above freezing, I found the combination Atom LT/Theta SV was almost too warm. That's a good thing, in my opinion, being as I am confident I won't need any extra layers unless the temp REALLY drops.

For sizing purposes, I am 5'11", weight 180, have a 33-34 in waist, and I went with a Medium. The medium is perfect as a slim fitting, layering piece, although if I were to use this as an around-town jacket, I would go with a large for a more casual look. For reference, I wear a medium in the Patagonia Down Sweater, which is a nice, casual fit. So the Atom LT does fit slimmer.

In conclusion- great jacket, great for layering, very pleased

Read the reviews. This jacket is awesome. I am not going to give you all the details. You will find them in the glowing reviews listed here and on other websites. I am up to my eyeballs in Arcteryx & Mammut jackets because they are the best overall quality. The Arcteryx Atom lt. is my all time favorite jacket. It is incredibly warm and light and looks outstanding. I have worn this jacket all winter by itself and as layer underneath a gore-shell jacket. It is a very versatile jacket for the spring, fall, and winter seasons. I am an athletic 5'9" at 160lbs and a large fits nice with room for a layer underneath. At the risk of sounding obsessed, I bought the hoody and vest version as well. I love this jacket. It is extremely versatile, light, warm, somewhat breathable, wind & water resistant. PS I bought the vest in medium for snugger fit.

This is my most grabbed jacket when i leave the house. It just feels cozy and feels like the perfect jacket for a wide variety of Colorado/Utah temps. It's my favorite mid layer for cold weather. It's the perfect weight mid layer under a shell for skiing and under a soft shell for winter hiking. The fleece side panels really help it breath when you're sweating. The styling is plain enough to double as my every day cubical life jacket which makes it easier to justify the price tag.

Hi all, which size would be best for me?...

Wear this jacket on a daily basis. Love the warmth to weight ratio. Can wear it in wide range of temps which is great for the ever changing CO weather. My go-to in pretty much any situation.

Perfect syling to fit under a hardshell for extreme weather. Great as an outer garment for fall weather. Warmer than you would expect. Blocks the wind great except for the stretch panels.

It is really bright in person! Because of this I'm going to return it. It should be called "construction worker orange."

How do you wash this? Would it be ok to put into a front load washer and use regular detergent?

Most recommend using tech wash or similar because normal detergent can break down the dwr finish. Washer is fine, front load is better than standard agitator type, I would use gentle cycle.

How do the atom jackets compare with TNF redpoint jackets? In terms of warmth, compressiblity, duribility and face fabrics.

Hey Benjamin Vincent,

Thanks for the question. There are a few differences when it comes to the Arc'teryx Atom LT Insulated Jacket - Men's
and The North Face Redpoint Insulated Jacket - Men's. The warmth between the two will go to the Redpoint as the Atom LT has a bit more insulation than the Atom LT. Compress-ability however goes to the Atom as it is a slightly smaller fit and has less insulation to push around. Durability is a bit of a wash due to the nylons of the outer fabric having similar strengths, but the Atom has a DWR coating for better precipitation protection than the Redpoint and has a smoother feel as well.

Also I would add, the Atom LT is more fitted slim fitting as the Redpoint is not, just a loose regular fit. I had the Redpoint so I know. The Atom LT is also more technical and the Redpoint being more casual. The shell fabrics are totally different, both have a DWR coating but the Atom is a matte sheen and feels tougher but not as slick as the Redpoint. The Redpoint doesn't have the stretch fabric down the sides either, really much different jackets, but I would pick the Atom hands down. I think Arc has a better product imo.

I'm 6' and about 175 with an athletic build...to get the maximum warmth from this jacket in the teens and below. I'm looking to use this as my heavy midlayer for the downhill, and as an outer piece for touring and slackcountry hiking. I rock a medium sidewinder SV, but am concerned a medium will be too snug and constricting.

I'm heavier than you and I can pull off a medium without any trouble. Go for it.

I primarily use this as a mid layer for resort skiing on very cold days, and it's great for this purpose. The breathable side panels really help to maintain comfort under a shell. At a slightly pudgy 6'1" 185 lbs, the large is a pretty snug fit for me (as is typical with Arcteryx). This works out well as a midlayer, but if I wanted to use it very much as an outer layer I'd probably want to size up.

I've ordered, and returned, two of these jackets so far.

The good: They are fantastic in build quality and fit, and in short trials walking the dog (tags still on) they are very warm. I'm looking forward to getting my third one.

The bad: the color pictures on the website (and on Arc'teryx's website) are not accurate indications of the color of the jacket. For example: Squid Ink, which looks to be a nice blue/periwinkle, is actually a deep purple; Tibetan Red, which looks like a nice dark red, is also more purple than red, with a ridiculous light orange lining.

Not being man enough to pull either of those colors off, I'll be placing my my next order for the black version. Hopefully the third time will be the charm.

This jacket receives my praise on so many accounts that even at full price, it feels like a bargain.

To better understand my use of the jacket, it may be worth noting that I live in a coastal desert region. My need for a jacket is limited to cold nights and mornings, a few short winter months, and travel to colder regions. That being said, the Atom LT is light, compressible and breathable, which warrants having it on me much longer than I would a heavier jacket. This is one of the main reasons for my purchase.

Others have mentioned that the piece does not appear very "technical" while still offering great performance. This jacket suits a casual setting just fine. Not everyone will care about that, but kudos to the bird for designing a jacket that excels in both performance and aesthetics.

Lastly, I am probably one of Arc's huskier customers, and I don't always get along with clothing labeled "athletic fit." The XL fits me JUST right and with excellent range of motion. It is like wearing nothing, and I don't look like the Stay Puft Marshmallow Man, which is a good thing..

Money well spent.
