Beautiful and highly functional in layering system
I love the everything about my Atom LT Hoody in 24K Black - the look, the feel, the warmth, the mobility, the light weight, the durability, the pockets (fit my Venta AR gloves one in each side pocket when I need my hands free), the elastic cuffs, the zipper and the hood design. I thought the Norvan SL Insulated Hoody would always be my favourite but the Atom LT is now king in my closet. I'm using the following layering system now: BASE=RHO LT Zip Neck MID=Delta MX Hoody OUTER=Atom LT Hoody or Norvan SL Insulated Hoody And this layer system has been fantastic down to -10C so far.
Nice jacket overall, could be harder wearing
Bought this jacket after wanting one for ages and reading a lot of positive reviews. After receiving I found myself really looking forward to wearing it for all occasions from watching my son play football to showery walks on holidays. Cooler weather, rain showers, not a problem, this jacket takes it all in it’s stride. Disappointed when after a 3km stroll wearing a pack the face fabric has visible signs of wear. Upsetting having only owned the jacket a few months. Still a great jacket overall, face fabric a bit delicate so don’t wear it with a rucksack or let anything catch the fabric.
Great garment but falling apart
I bought the Atom LT on 9th of March, have worn it 2 times, have not washed it yet and the left sleeve started coming undone - the stiches where the elastic waist band is. This is quite unfortunate as I have spent a lot of money on the Atom. I did really enjoy the fit, feel and warmth and I would recommend it to everyone, however it is really unpleasant to have it falling apart for such an expensive garment...Now I am afraid I will not be able to use it and I have scheduled a couple of cold weather expeditions where I wanted to use it... one of which is climbing Grossglockner I hope Arc'Teryx stands up to it's name and does something...
Abysmal quality
I bought my Atom LT on the outlet store last summer but didn't wear it until the fall. I used it for 30 - 40 hours of backpacking over a two month period, and sporadically on short hikes and while walking my dogs. I had bought a second jacket in the same class as the Atom from a budget brand and only used the Atom when the forecast was calling for high winds due to its amazing hood. Midway through the fall, I noticed the back side of the Atom's zipper garage had begun not only to pill, but appeared to be shriveling up and dissolving (see first picture). I've owned a number of Arc'teryx items and have come to love the brand based on the quality of it's clothing, so I was surprised and disappointed to see the fabric of one of it's signature items fail so quickly. Nevertheless, it didn't seem like a big deal to have a seamstress sew a thin piece of felt on to that area as well as the other parts of the jacket that rubbed against my chin which had also begun to show premature signs of wear. I decided to wait until next spring to have that work done and put the jacket into storage. It got unexpectedly warm and windy this week, so I took the jacket out of storage and noticed, for the first time and to my dismay, that there are two large holes in the insulation in the back of the jacket (see second picture). Shining a light on the jacket revealed that much of the remaining insulation in the back has begun to thin and separate. A detailed inspection also revealed insulation escaping through the stitching (see third picture) and pilling on the brim (see fourth picture). My budget insulated jacket, in contrast, still looks new, despite even more use than the Atom. My Gamma LT, which I always wore over the Atom and the budget jacket, and which I've never been delicate with also still looks new. I will never buy another insulated jacket from Arc'teryx and may turn towards other brands in the future for my high-end, outdoor performance clothing needs.

This Atom LT Hoodie is hands down my favorite jacket. Not only does it look good and have a flattering slim silhouette, it will keep you very warm. I bought it for the Northeastern winter (USA), and have yet to really test it's limits. The lowest temperature I have worn it in is around 25-30 F and felt comfortably warm. The best part is, I have worn it in 60 degree weather and felt equally as warm. The jacket does a brilliant job of regulating heat, which is probably my favorite quality of this piece. If you're looking for a mid-layer that can be worn in a mild winter as well as spring, this is should be your go-to piece!
It is not valid for men
After a month of use, I have worn the jacket four counted times, and the interior is destroyed (see photos). I don't have a beard, but according to the manufacturer, the wear on the jacket is "normal with use." The jacket is very soft and pleasant to the touch, unfortunately, if my chin does that to it in four days, imagine what the vegetation in the forests does to it, which also have multiple tears. If it's a little windy you need to wear a third layer, so don't wear it "on its own" as they say on the web if you don't want to freeze. Due to its lightness I can recommend the women's jacket, to carry it in the backpack in summer, as long as it is used with a third layer.

Retire Your Fleece --> Atom LT
The Atom LT is an amazingly versatile piece of gear. Most of the jacket is wind resistant nylon that helps keep you warm in blustery conditions, while the stretchy fleece side panels are very breathable. The weight of the insulation in the Atom LT is slightly more than a winter weight fleece but so much easier to layer with as you can slide it on and off and under other layering pieces with ease. In the 40s perfect for town roaming around town with a T shirt underneath. In the teens, it is great under a hard shell as a layering piece for skiing or as an outer layer for fat biking with long under wear underneath. This is the new mid layer of choice perfect for so much.
My Favourite!
I pretty much live in this jacket. I wear it out and about, or even at home. We've had quite a cold winter so it's been my go to jacket for hiking. I'll often wear it during hikes or sometimes pack it as an extra layer. It's comfortable, breathable and lightweight. I love the colour too! Now we're in to the spring, I'm still wearing it quite a bit whilst the temperature is still rather low. An all round great jacket!
The face fabric of recent models is very fragile
Arcteryx Atom LT used to be my favorite jacket for years. It is lightweight, warm and versatile. I used it as mid-layer for hiking, biking and walking around town. However, I am disappointed by the latest models. Indeed, the face fabric starts to pill just after about a year. The pills are very easy to be seen at external chest region and around the internal chin region. See the attached photos. The jacket is manufactured 2018 according to the tag. I have another one manufactured in 2019, let's see what will happen after several months. I think I would not recommend the recent models.
Best Jacket I've Ever Owned
I've owned this jacket for five years, and it is still my favorite jacket in my closet. I wear it during three seasons of the year, and for every activity: hiking, x-country skiing, downhill, snowshoeing, fishing, and climbing. It has excellent mobility and, after five years of almost daily use, it's still in fantastic condition. I have washed it about 10 times so far, and it hasn't damaged the insulation. This jacket is near perfect. My wife had to talk me out of buying another one last week because my current one isn't beaten up enough yet to warrant another purchase.
