Customer Reviews Arc'teryx Atom LT Jacket

I purchased this jacket as an alternative to my down jacket. Last season I wore a down jacket on super cold days under my shell, it was fine most of the time but occasionally it would get damp or I would get way too hot. The Atom LT has been great as an alternative, it breathes much better, it is still warm, and it is not as bulky. I have been wearing this more often than my down jacket, whether it be as a midlayer, an outerlayer for mild days around town, XC skiing, climbing, or around the house. the Hardface shell material does a great job of repelling water and keeping the wind out, but on windy days I can feel the wind go right through the fleece sidepanels. The stretch wrist things are one of my favorite features of this jacket because it just feels better under my jacket, under gloves, and especially while climbing. It makes the jacket a lot more durable having it away from your hands. When you pull the sleeves up and away from your hands the stretch wrists make it stay. Overall this jacket is growing on me and I find myself putting the Atom LT on more and more than my down jacket or a fleece

I bought this jacket because I love my Atom Hoodie to bits but sometimes the hood is a bit too much to deal with when layering with my shell. Layering with this piece is amazing, it's great on it's own, with a fleece, or a shell when it gets really nasty out. I love how warm it is for how light it is. Please never stop making these jackets!

I absolutely love this coat. In fact, I think it might be my favorite all time. It is a good coat for good weather days or to wear as a midlayer on poor weather days. The coat is so light and comfortable that it doesn't feel like I am wearing a coat. The cuffs are soft and offer a good amount of stretch. I much prefer these cuffs over the typical stetch band cuffs you see on most puffy coats. It doesn't have a lot of bulk, so it feels great under a shell but is still plenty warm. I wear this and my Stingray with a t-shirt at around 25F, and I add a thicker baselayer as the temps drop. I can easily go to 10F with a midweight merino as a baselayer. The fit is perfect as far as I am concerned. I am a typical medium, 5'10", 40" chest, 32" waist. There is enough room for a heavyweight crew neck baselayer, but still tight enough to work well as a midlayer. I would not want to wear a fleece under it. It fits perfect in the waist with no need for a draw string. There is a good chance you have the wrong size if you need a draw string. Don't size up with this jacket to use as an outer piece or you lose all the wonderful qualities of it. There are other jackets that serve that purpose better. The side fleece panels do a good job of venting, and it dumps heat well if I have to open the pit zips on my shell. Overall it is a great coat for the purpose I use it for, and I couldn't be happier.

I was a bit reluctant at first because this jacket is rather plain to look at. However, this jacket is incredibly light and yet extremely warm and breathes really well. You cannot really tell you are wearing it! I have never had an article of clothing quite like this. I have worn it running in cold temps (-20C) and am looking forward to using in under my goretex shell for cold skiing days!

This jacket is one of my favorite mid-weight layers due to it's warmth, it's weight and it's wind resistant capabilities. I use it for a single layer as I commute to work and around town and the fit and wind protective properties are absolutely amazing. The side vents prevent me from overheating and even keep the wind out when I'm moving. I've used it with my shell in 14 degree F ambient and a wind chill of 0 and I was fine. I'm 5ft 8 and the small fits me perfectly. I even took a spill and skidded on asphalt for 1-2 feet and only got minor tears in it after that. Even though it looks light and not very durable, it will surprise you. I will definitely recommend it.

I love it. I went skiing in about 0 degrees C with only a base layer (Icebreaker 200 wt) underneath it and a shell on top. I warm the whole time. It's really well thought out. If you are wondering about it, simply try one on and you'll want to buy it. It feels so good. The pockets are really well done. The cuffs are spectacular! They really are perfect. I'm 6'2" 170-175 lbs and I got a large. The medium technically "fit" but the large was a better fit. It runs a little small. Oh, and get the tibetan red. Greatest color ever! Red interior. It's sharp. It's warm. It blocks wind great with the exception of the side stretch panels, but that is a good thing for some ventilation. It's one of the best jacket designs I've ever seen. I've tried to think of some way it could be better because I really like gear, and I still haven't come up with anything. (ie: see my review of the venta lt glove) This this is perfect! Now if only the SV came in a hoodless version. Best layering piece I own!

Have had this jacket for nearly a year and love it. I take whenever I go tramping because it is so light weight and compressible and works well with the phase base layers and fits well under the alpha lt. I also use it around town under my ventar AR jacket and found that was warm enough through the winter in new Zealand and had no use for my down jacket this year. This jacket does fit quite snug however I am a small in arc'teryx but feel I could probably fit a medium. All round though very happy with my atom another great Arc'teryx purchase

This jacket Is kind of like a Swiss Army knife... it can do pretty much whatever you need it to do. It stops the wind decently considering it is not a shell and its water resistant as well. It is warm, but breathable, plush but compressible. It layers very well with a hard shell, but wears great by itself. It looks great too and its something you definitely wear out like a North Face jacket (except this jacket its way cooler and more functional). I wear this with my LEAF Alpha LT jacket and it absolutely rocks layered with that shell. The system is very warm especially considering how light weight and term it is. I use that combo for skiing and it kept me warm in 15-20 deg F weather with some decent wind without a hitch. Both jackets fit pretty trim. I have a medium in the Alpha LT and a large in the Atom since it was pretty slim in the hip area.

I wasn't looking for a crazy downfilled insulating layer or a arctic winter style jacket. So I am glad I got the Atom LT. I am 6'2 150lb athletic male and the sizing is fantastic (I got medium). I wear it as a solo piece or under my other shells. It is warm enough for spring and fall but still very breathable (heck I've even worn it in the summer). I do get cold so I would need to bulk up a bit more in the winter under my shells if I wasn't active, everyday kind of stuff. I am happy with its breathability and weight. I have friends with this jacket and they say the same thing. If you are looking for a lightweight insulation piece for active winter wear or seasonal everyday wear than this is the jacket for you.

I use this on non-windy days as a lone top. The side vents do allow you to release heat when active, but let the wind in and cool you off if you are standing still. I had it on a multipitch route and got colder faster then I thought that I would because of the side vents. That being said, I topped it off with the Squamish Hoody and was totally warm because that blocks the wind like a champ!

Our warm fall weather has been perfect time to try out my Atom. It replaces for me a 10-year-old Atom that has been my travel jacket, mid layer, and all around, versatile warm-up. The new one arrived with lots of folds and wrinkles and is not as trim as my old one but I'm still wearing it on the warmer December days.

Jacket is almost perfect. Lightweight but warm. I love the water resistance ! But my biggest complaint - PLEASE FIX THUS ARCTERYX !!! : The flap that goes over the zipper on the collar needs to be slightly bigger so that it fully covers the area right below the chin. Otherwise the top of the jacket doesn't tuck into the flap and it will scratch your chin. Makes an almost perfect jacket a bit uncomfortable when zipped up fully.

Just received my Atom LT Jacket. Immediately noticed the lack of insulation. It feels like there is just the lining and the outer layer of fabric, no insulation. I have a Atom LT that I purchased appx 4 years ago, it has insulation I can feel. Also, do not like the knit panels in the sides.

Product is top notch BUT what's with the white collar liner and most of the jackets lining thought maybe you would coordinate with exterior shell.

Lighter and less warm than I expected. Fits well and looks good. Not the greatest value butt ok, It does compact well.

I have 2 Atom LT vests already and a variety of midlayers (Proton FL, Practicioner AR) in size L. This is a bit roomier fit in size L than I am used to, but some might find that advantageous (I am definitely more on the slim size in abdomen, wider shoulders). Great for all-around use. Kingfisher is a great color with just as much casual appeal as Black, I find. Very warm for the weight.

Great simple jacket for wearing around the city and doing outdoor activities.

This is my second Atom LT jacket and first without the hood. I love the new design; it fits much better across the chest and shoulders compared to my 2019 jacket. What I don't like is the inside collar. I have this jacket in the dusty pink and the inside collar is black microfleece. It shows everything--fuzz, dry skin, etc. And, while I didn't notice it at the time when I tried it on, I realize now that when the collar is not all the way zipped up, the black breaks up the jacket from an aesthetic point of view. I think it would be much nicer looking to have the same colour of microfleece lining the collar as the colour of the jacket. I do love these jackets as a stand-alone or layering piece. But, I won't buy another (hoodless) if the inner collar lining does not match the colour of the jacket.

Works great as a midlayer. I use this under my Beta AR because it doesn't have a hood, and my Atom LT hoody as a standalone piece and midlayer under jackets that have stormhoods. This and the hoody version are becoming my favourite pieces of clothing, they are very comfortable and the fit is spot on. They don't restrict movements at all. Only thing I'm worried about is the durability of the face fabric, it feels a bit delicate. I've had a few branches brush against the fabric but luckily no rips so far. Lighter colours might stain easily, so be wary of that.

Bought this specifically as a mid layer for high output cold weather hikes. I have tried many mid layers over the years and always had the same issue, they did not breath. I'm excited to say that I think I finally found the holy grail! This jacket is light enough to pack, warm enough to wear as an outer layer most of the time, and breathable enough to hike in. Once you stop, simply throw on a shell or down jacket. Great addition to my cold weather gear collection. Very happy with the Atom LT.

Hubby has worn the Atom jacket and vest for many, many years. It is perfect for the Pacific NW weather. The elasticized panels aid the range of motion and layering capabilities. Although he strongly prefers the function of the hood, I prefer the collared jacket as it looks slightly more dressy. The jacket is nearly indestructible. I subtracted 1 star due to the unavailability of larger sizes, specifically 3xl.

Love the 'Muse' green colour-way! I have a couple of other Atom LT jackets in black/khaki and live in them ALL the time. This jacket seems a slightly roomier 'medium' cut than my other Atom LTs BUT - a design detail that I didn't see in the product photos - I'm slightly disappointed that the interior lining colour doesn't match the lovely green of the outer, or the interior collar. The inside collar fabric is black which looks good, but the rest of the lining fabric is a pale minty green which (I think...) cheapens the overall look of the piece; I'd prefer to have the lining colour in black or the same green colour as the outer - it just looks more minimal and stylish imo. A small detail for an otherwise brilliant jacket.

I recently bought this jacket as a layer whilst hiking in the winter. It is amazingly warm, but not as breathable as I'd hoped. That said, it is designed as an insulating layer mainly. I would happily recommend this product.

This jacket is a spring must. Absolutely love it..
