Versatility at its finest.
After one use, you'll want to keep the Arc'teryx Women's Atom LT Hooded Insulated Jacket close by throughout the year. Wear it by itself from spring to fall on chilly outdoorsy adventures whether you're backpacking or hiking, and then slide a waterproof shell over it for ski sessions in winter. Its Tinthan shell keeps the Atom LT light yet strong, and the DWR coating sheds light rainfall to help keep you dry. Polartec Power Stretch side panels wick moisture, dry quickly, breathe, and provide a four-way stretch for uninhibited mobility.
Arc'teryx also added Coreloft insulation that uses air permeable panels to ensure excellent thermal regulation. A trim fit helps you layer over the Atom Lt with ease, and the StormHood is adjustable, insulated, and helmet-compatible. This jacket also features an adjustable hem for a secure fit, two zippered hand pockets, and one zippered internal chest pocket.

happy days in the Uintas with my Atom LT
Best all-around jacket on the market
I used this jacket basically every day last winter and on those chilly spring days. It is a great mid layer to wear under a shell for skiing and some days I found it was too warm but I would rather be hot than cold. It has great ventilation panels that run a little past the armpit. Great all-around jacket and it has become an essential piece in wardrobe. I love the black so much I have 2! I already ordered my 3 jacket but in a different color this time around
I wear it on the river, skiing, running around town, I basically will find any excuse to wear my Atom LT. Great quality, the jacket does not look worn at all for wearing it everyday.
Although it is a tad expensive the jacket will pay off. Splurge a little!
my fav for fishing on those chilly days
Atom LT, the perfect outer layer
I wore this jacket literally every day for about 4 months, and after a good wash, it still looks like this! It survived an Alaskan summer with out a sleeve tearing, a thread breaking, or zipper sticking. And it is still a nice warm layer for snowy fall hikes.
Atom LT Hooded Jacket
I love this thing. I have a white one and a black one. I use them
Running around town
and if I skiied or climbed I would use it for that too! Great all around piece for you closet.
The piece for everything.
My Atom LT kept me warm and dry during a rain storm out fishing the Provo river. This is an awesome piece. I have a couple more colors in the mail :)
I've brought it to Nepal for a 6000m+ peak last December.
I was wearing this for straight 20days throughout that winter even though we started at only 16deg cel on Day 1 at Lukla and the coldest was -10deg cel.
Of course, I played around with the layering of other thermals. This jacket basically acts as my outer shell most of the time. Would buy it again if i need to!
His & Hers :)
we absolutely love our Atom Jackets! They are perfectly packable, available in killer colors and the stretch side panels allows for all kinds of movement. ..climbing, hiking, skiing, running, dancing .. anything!
I love this jacket so much I bought two.
Excellent fit, warm, super packable, and the colors are awesome.
Perfect for Fall Climbing
Atom in the North Cascades
Hiking through the unpredictable North Cascades in the fall - the Atom was our go-to choice.
What's the length from shoulder to the bottom of the jacket? It says hip but the reviews seem mixed for various heights.
Re: Arc'teryx Atom LY Hooded Jacket sale -$194.25-Color -Mirage
Please advise me why I receive ads selling this jacket but cannot actually purchase it --because I live in Canada..? I have checked and can buy said jacket for 290 but not in the color I want.....Seems Canadians are always getting the worst treatment possible....Await your response....thank you for your time....
I have sent you an email. Looking forward to your response!
what color is the lining around the hood on your atom lt hooded in color Silver Lining
The trim around the hood is Pink, very similar to the Guava Pink jacket, in the Silver Lining color of the Atom LT.
I'm interested in the atom lt silver lining color and I'd like to know what does the color closely resemble because the picture looks white. I would use it for learning how to ski so it would be getting damp from the snow . I am 4 foot 11, chest 33 and 108 pounds, do you think the extra small would be fine or would you recommend something else .I do not like anything bulky and I would like to be able to move around good. I do tend to get cold easy. Are there any other lightweight jackets that you would recommend for a petite person like me.
The Silver Lining color is an off white, soft silver grey. The Atom LT is a versatile, lightweight jacket but it would not be the best choice as a stand alone ski jacket. You could wear it under a technical shell like the Arc'teryx Alpha SV or the Ravenna. Your other option would be to get an insulated ski jacket like the Arc'teryx Andessa or the Fission SL . Feel free to contact me directly to discuss your options or if you have any other questions about Arc'teryx Jackets.
I'm studying for a year in Lausanne, Switzerland, and am wondering if this jacket would be warm enough for those temperatures in the winter (will be between 25-50 degrees Fahrenheit) as a stand-alone jacket over a base layer.
Hey there! I love this jacket and it has served me really well in many conditions. However, I wouldn't recommend it for any colder than 40 degrees F as a stand along jacket over a baselayer, unless you're hiking or climbing and working really hard. It is a fairly light jacket really and the wind penetrates it thoroughly. The Atom AR has a bit more serious insulation and will be a bit warmer, but you may want a high fill (750 or so) down jacket if the temperature will be closer to 20 regularly. Maybe the Thorium AR Hooded jacket? Hope this was helpful.
Am almost 5'11" and am roughly 145lbs..slender but tall...leaning toward buying one but not sure if M or L...recommendation?
I would recommend going with a Large in this particular jacket since it is a trim fit. If for some reason the Large does not fit, we can always help you exchange it for another size for free.
Feel free to shoot me any questions about Arc'teryx jackets:
What is the center back length of a medium?
How is the length of this jacket? Does it run longer or shorter?
The Atom LT is hip length, so somewhat short when compared to a jacket that is thigh length.
which is warmer the Atom AR or the Atom LT jacket?
The Atom AR. It has 40g more of insulation and the side panels are fully insulated as opposed to the LT which has Polartec hardface Wind Pro side panels for better breathability. I own both. The LT is perfect for being active in cold weather and a standalone piece in fall and spring. If you want pure warmth the AR is the LT on steroids. Coreloft is my favorite synthetic insulation thus far.
