Arc'teryx Atom LT Jacket - Women's for Sale, Reviews, Deals and Guides

I love this jacket! I was looking for a good jacket that could be used for a Montana spring or fall. Surprisingly, this lightweight jacket can be layered and easily work for winter as well. I am amazed at how warm it is with it being relatively thin. It is also great in wind. This is my new go-to, multi-season jacket. I am 5'2", 110lbs and the XS fits great. It is too snug to wear a big sweater underneath, but even in 30 degree weather I find I don’t need one. It is perfect to put a winter shell over for those brutally cold days. I'm sure if I would've sized up I would have no problem wearing either something bulky underneath or multiple layers, but I prefer it form fitting.

I bought this jacket for my sister and she loves its warmth especially since it doesn't wet out like down jackets. She wears it most days of the winter and occasionally in the spring and fall. It’s the perfect weight and easy to wash and care for. She's 5’3” and 115 lbs and went with the small.

Bought for my wife, here is her feedback "I love this jacket. I love everything in the Atom LT line, but the jacket is amazing for every day wear, in Virginia...February through May, New York...April through June. You do need to be a little bit careful with the pockets - my phone falls out of it all the time if they aren't zipped, but shame on me for not learning that lesson. I have the black, and it great for casual wear no matter what the occasion."

I bought this jacket just a couple weeks ago and I am already in love with it. Its a super light but warm jacket for any mid-weather adventure (just in time for spring). I'm planning to bring this on every trip I take in the spring and summer. It's perfect for aerobic activities as it captures warmth without overheating. The fit is also a plus for me. I initially tried the XS and it was just a bit too perfectly snug in the hips and a bit too short for my liking. The small was perfect! Just a bit loose for any layers but still sleek and trim. Cant wait to wear this even more.

This jacket was clutch climbing Cathedral Peak in Yosemite the first weekend of November. It kept the cold at bay and when we moved into the shadows it paired well with a light windshell. I did a little spot cleaning from climbing dirt and then wore it to the office. Love it!

I highly recommend this jacket. It's high quality and lightweight, also comes in a lot of awesome colors. I definitely recommend this!

The Atom LT is my go-to puffy and ultimate layering piece for everything outdoors. I wear it under a shell skiing and as a stand-alone jacket on chilly days. It keeps me warm enough in cold temperatures, but breathes well enough that I don't steam up. It has stretchy side panels made of Polartec Power Stretch that are flattering and vent heat, while still keeping you warm. The pockets are even fleece lined to keep your hands extra warm. While the performance of this jacket is amazing, the comfort of this jacket is even more impressive to me. I would literally wear this jacket every day if I could. It is so soft and feels like butter when you're wearing it. Another consideration when purchasing a puffy jacket is durability. I've had mine for eight years now and it still looks as good as the day I bought it. The fit is slightly trim fit, but tapered. If you like a slim look, go for your regular jacket size, if you want extra room for layering, size up. I'm often asked as a Gearhead what my favorite piece of gear is. Hands down without hesitation, the answer is always the Atom LT. If you ever come into Backcountry's office during spring, summer, or fall, there is a seriously good chance you'll see me wearing one of my Atom LTs and a ton of other employees, as well. Basically, I can't think of a good reason not to have one. If you want the warmest version of the Atom LT, get the hooded version, if you want an even lighter version, consider the vest. If you have any questions at all about this jacket or even want to chat about how much you love yours, please call me at 801-204-4562 or email me at amcclary@backcountry.com

She absolutely loves it and pretty much where is it with everything she owns it’s warm without being too warm and has just enough room that she can wear something under it she absolutely loves it

The Atom LT jacket is a great addition to any closet! It has nice, breathable side panels that allows you to engage in high output activity without feeling the build up of perspiration inside the garment. This jacket is certainly an athletic fit (slim) and is a bit short on my torso - I am 5'8". A synthetic insulated piece such as the Atom LT is super versatile in all conditions, though I would recommend using it in milder temperatures such as 0 degrees celsius to -5 if you are going to wear it as a stand alone piece. I've used this jacket mountain biking, cross country skiing, hiking and camping.

I bought this for a friend who had the following to say: "There is so much to love about this jacket! First, this jacket is incredibly lightweight, more like an insulated sweater than a jacket. Despite its light weight, it is incredibly warm. I wear it with the Sentinel jacket. I use the Atom LT as my insulation layer to keep me warm, and the Sentinel as a weather and wind-resistant outer shell. Second, the Atom LT also can also can be compressed into a small space for travel. I do wish it came with a bag or could be stowed in one of its pockets. During the winter, I want to use this jacket constantly. Although, I would like a bag, its absence won't deter me from packing it everywhere I go. Third, I think the thing I love most is the Atom LT is incredibly comfortable. It is longer in the back for great fit, extra warmth and comfort. It also has snug wrists that keep warmth inside where you need it. The side panels are great for breathability, and I can envision using this jacket in a wide variety of outdoor activities. The Atom LT is a great, functional jacket. Overall, this is an Arc'teryx favorite for versatility. You cannot go wrong with this jacket."

This jacket has it all. It is compact, yet still very warm. It serves as a perfect outer layer for your daily needs, and can even be worn as an under-layer on those colder days! Definitely recommend this jacket to anyone!

Easy to pack, doesn't wrinkle, light weight, yet offers surprising warmth. I use it as a jacket to work, to bike or rollerblade, to cross country ski, as a layer under a shell for colder downhill skiing. Love the length a bit longer over the butt for extra warmth. It's close-fitting, yet the sides are stretchy so lots of movement. Have had this jacket for several years, well worth it. I got the roseberry color and love it. Most recently layered it under a shell for 8 degree skiing at Snowbird, UT! First time layering for cold and it performed perfectly!

... but really, just a touch. This is a great jacket for temps in the 30s (under a shell) or 50s-60s (alone) but if you're looking for some serious insulation, this is not for you. I know, it says "LT" -- take that seriously, and if you need something truly warm, go for the AR version instead. That being said, this jacket is fantastic when you just need a little warmth - super lightweight, very breathable, and very easy to layer over. Truly a 3-season jacket that can span a range of conditions. It's also very easy to layer over. I got the non-hooded version for maximum versatility. Like some Arc'teryx items, the fit is a bit of a mystery -- some things run small, while others are large; this one is in the latter category. If you're between sizes, I would recommend sizing down rather than up.

I love everything about this jacket except for the length! I am on the shorter side (5'4) and I still find it too short. Such a huge shame! Because otherwise it is perfect as a jacket for between seasons.

My wife has one of these and she loves it. The material is made out of dragon skin because she beats this to shit and has never had a rip or tear in the material. Insulation: its that perfect mid layer fill! keeps you warm! Fit: its going to be close to your body to keep you warm. Pro: Durable, Warm, and Lifetime Warranty Cons: she wished she would have gotten the one with the hood.

That's 5'-7" Katie in a size small Atom LT jacket. We rode my motorcycle to a walk around Ada Hayden Lake in Ames, Iowa and the Atom LT held back the morning's 26 deg wind chill temp. We both think the Atom LT is a great jacket (I've had mine for over 4 years). It's warm and lightweight and just feels great. With its athletic/trim cut, it looks great too. Highly recommended.

The Patina Teal is a darker teal in real life. It's much more green-tinted. I gave this as a gift to the winter runner in our family, and she loves it! Although the color is not as pictured, she still loved the color.

Close-fitting jacket works great alone for cold biking or under a shell for skiing. Very lightweight but very warm for what it is. Stretchy on the sides, wind and waterproof elsewhere. Nice deep pockets, no pit zips, tight cuffs on the sleeves. Good for a variety of uses. Longer in back keeps your butt warm too. Attractive fit a lot like the women's Marmot fit. I found it to run just a touch small - maybe just felt that way because it is so close-fitting. My normal size worked. I will use it a lot. The product description is very accurate and like any Arc'teryx product, the quality is superb.

I love this ultra light jacket. With its articulated sleeves and close fit it feels great over a light fleece or anything for that matter. Water beaded nicely in rain on last hike. It is a close fit, but has a little pouf to it - fabric feels light but takes a beating...Typical awesome Arc'teryx quality. Perfect for cold (not sub-zero) hikes and runs or with it's close fit, as a layering piece.
