Customer Reviews Arc'teryx Atom LT Hoodie

This is my 5th different Arcteryx jacket over the years and one of my favorites. So far I've found it comfortable (with only a T-shirt underneath) down to the mid-40's. I'd say its warmth is comparable to a mid/heavy-weight fleece with a windbreaker over it. In the backcountry I can use it down close to freezing when it's over a long-sleeve lightweight wool top, and under a rainshell. The hood adds a lot of warmth for minimal weight and confusion, although with the sacrifice of adjustment. My favorite part are the cuffs, which provide a really nice stretchy, secure fit (unlike some other Arcteryx cuff designs). They are perfectly low profile and wear well under a hardshell, and/or along with gloves. Fit and quality are typical Arcteryx best in the business. I really like the clean design that's free of the sewn thru seams you see all across most other synthetic-insulated jackets, and also has a nice matte finish to the shell material, rather than the glossy sheen of most insulated outdoor pieces. My only complaints (as I've seen others mention) is that the main zipper easily comes down on it's own. Arcteryx really needs to change this to a locking/stiffer zipper design. Also, the fleece sides/underarms have begun pilling after two seasons, and hold odor much more than the rest. I wish they'd just use a low profile nylon there instead. But these are slight annoyances for what otherwise is a perfect insulating mid-layer.

The Atom LT has a very nice fit for a middle/outer layer - nice and tight. It has a good warmth in it. The stretch part sidepanels work surprisingly well to dump heat when it gets too much. Also a problem though, when it's windy and you are not active. The cold wind blows right in under your arms... But that's where a shell jacket comes in handy. I'm a bit disappointed with the hood. There is no way of tightening it around your face and it is not small/tight enough to stay where in place. Also, when not using the hood, the neck opening in the jacket is pretty big and lets a lot of cold and wind sneak in.

If I am going out for a walk or going to ascend a mountain, I bring the Atom LT. In the winter I use it as a stand-alone jacket for shorter periods outdoors or under my Alpha LT in colder more windy conditions + Light Packs very small Covers a great range of activity level depending on temperature - No way to tighten down the hood

Great jacket, lightweight, yet warm. Please come up with brighter colors, as they used to be. I would like to have another bright red, blue, teal, something fun!

I love the jacket, but I had to return it because of the sizing issue. There's a huge size difference between large and Extra large. The shoulders are very wide like as if the jacket was only meant for Olympic swimmers. Arcteryx, I love your style but you need to fix the fit and sizing issue.

So I love the warmth, and the quality of there materials, but it's not fitted enough. The sides being stretchable allows the front to sag. And the had pockets are too small.

The purple color is very beautiful and the reason I am keeping it is because of its color! However, the material is not thick and limits its use to early fall or late spring. I cannot imagine to wear this in winter or any cold weather. I ordered Large and Xlarge and at the end I kept the XL. The sizing is not good. The large one was tight on bust and good on waist. The XL was good on bust but too big on waist. So, if you have large bust size, I recommend going one size big but at the same time it will be big in waist. I wish Arcteryx jackets were a little bigger in bust area since I have the same issue with their Beta AR series.

I bought this to test out the new fit. Overall I've been impressed with the design and quality of materials selected for products. The fit has always been the reason I've not purchased. I WANT to like the fit, but even with the new sizing and the stretch side gusset, the jacket is riding up above my hips. I'm also a bit unsure if I like the fabric feel, it's almost too synthetic feeling. Lastly, the cuffs are tight. There doesn't seem to be a lot of give which may be the dealbreaker for me in using this jacket regularly. From a sizing perspective I think the brand is still missing the boat by designing for a limited size profile. There are plenty of folks with the funds to invest in the product, but the fit is nearly always the issue.

Fit is everything and unfortunately this didn't work out bought medium, shoulders and chest fit perfect. Waist way to baggy/boxy, sleeves were also quite loose and too long. Would have sized down but small too tight along the chest. Arcteryx sizing is no longer for athletes unfortunately..

Nachdem ich bereits die Atom LT ohne Kapuze hatte, wollte ich nun gerne das Modell mit Kapuze. Verarbeitung und Material waren beim Hoodie genauso gut wie bei der vorhandenen Jacke, aber leider hat sich der Schnitt bzw. die Gre verndert. Das Modell ohne Kapuze passt mir in Gre L perfekt, dass Modell mit Kapuze ist in der gleichen Gre dagegen deutlich schmaler und krzer, und die XL ist dann wieder viel zu gro. Schade.

I have a 10+ year old Atom that I absolutely loved. I decided it was time for a new one that didn't have as many holes (oops). The new jacket is warm and clearly has better zippers and cuffs. However, the face fabric isn't quite as soft and the fit is much bigger around the stomach. This makes the jacket less comfortable and bunch funny. I tried on a medium after purchasing but found it was too tight around the shoulders and a bit short. I wish Arc'teryx would go back to their older sizing that was designed for a more athletic build.

I own older models of this jacket. Early 2014ish. Excellent quality. The new designs are horrible. Quality is poor, sizing is off. My new jacket, bought in 2020, is beginning to unravel and unthread. It seems like the company is no longer focused on true quality outdoor products.

I've had this jacket a few weeks and have worn it nearly everyday. I believe I was mistaken at how rugged I could trust the jacket to be though. A small ember caught my sleeve last weekend and burned a decent sized hole in the sleeve. I took it the next day to the re-bird center hoping to find a good solution but was given a black nylon piece to tape over the hole. I wish I had a better option to patch it! Not loving the look of it now.

It is so frustrating that the women's version of this has the awful fleece side panels, while the men's version does not. Why have an insulated jacket if 1/3 of it isn't insulated?!? I also find the zipper comes up too high and is uncomfortable under my chin. I wouldn't wear it done up unless it was so cold that I needed to bury my face in it, in which case I would be wearing a warmer jacket. Please make it the same as the men's. I like the style better than the Proton (and there is a much better colour selection) but I dislike the side panels so much that I'm not sure if I will keep it.

I've been putting-off buying an Atom LT for a few years. Last night listening to the Backpacking Lite podcast they were discussing the benefits of 'pull-over' insulation layers (lightweight, more packable, users do not add/remove as frequently as a wind shell so benefit of a full-zip are fewer, and the possibility of a 'kangaroo' front pocket for added hand-to-hand warmth). Additionally, with the addition of Proton to the lineup which features breathable face/outer fabrics for high-output activities, the side stretch panels on the Atom LT -touted as a means of 'dumping excess heat'- really only serve to provide less insulation where it is most needed on an insulation layer.

I just got this jacket and I was very excited to have it in time for spring backcountry touring. The fit and insulation along with the color is perfect EXCEPT the zipper. I ordered a size up concerning that may usual size would be too form fitting and the jacket fits perfectly, even slightly loose to allow for layers. When a move or bend over the zipper slides down and the jacket unzippers, it doesn't stay up! For the cost and reputation I expect way more.. I'm disappointed and don't know what to do because I love the jacket otherwise.

Really disappointed with this. Looks the part, very thin, but adds virtually no warmth. May as well be wearing a pertex windblocker.

I just purchased this jacket in Mesmer and as others have noted the product is no where near the bright purple/pink shown. It would be great if arc-teryx had bright color options in this jacket, maybe something to consider for next season. If you look at their photos for the SL jacket the Mesmer color is more accurate in those photos. Arc'teryx really needs to pull the Mesmer photos and repost with a more accurate photo (other wise this is false advertisement) The jacket itself is fine but not a good as the old fit from a few years back (now I size down). Overall the color is still nice, just purple and more muted, so I'll keep it. With that said, I do think a lot of people will be sending the Mesmer color back once the see how off the color is.

I bought this jacket and wore it for 4 months and really liked. I washed it once in a front load washer as recommended and it came out with two spots where the fabric pulled and made a pucker. For the cost of this jacket I would think it would hold up better.

My seatbelt has nearly eaten through the rip stop after only 6 months of owning this jacket. Killer jacket overall, fragile for its price point

I have been using the Atom LT for over 3 years as a three-season jacket. As the insulation on the shoulders have become significantly compacted due to backpack-carrying, I decided to get a new one this past month. I bought the same size, only to discover the sleeves in the current model are much narrower, while the bodice has become much longer. I felt I was trying on pyjamas instead of a mid-layer jacket! In addition, the new stiff upper lip (no pun intended!) of the hood caused more cold air to seep in when walking in high winds. Last but not least, the embroidered logo is rather stiff and digged into my skin, which I find rather irritating. So I returned it.

Further to a previous glowing review about the warmth and weight, I would advise that unless you can be assured of the jacket not coming into contact with any surface, do not purchase. I literally just brushed against a brick wall and the fabric has torn. I'm staggered how fragile it is. Totally disappointed with the resilience of this item at this price point.

I bought this jacket last winter to replace my Cerium LT. The good: very good fit all round - shoulders, chest, hem line doesn't move when I stretch my arms up, just like my Cerium LT and the main reason I went again for an Arc'teryx jacket. Outer material is more robust compared to Cerium, which is reassuring as I mostly wear the jacket as an outer layer. The bad: The most annoying problem is collar height - when fully zipped up, it neither covers my chin nor stays comfortably under it always rubbing under my jaw. For this alone I cannot rate the jacket any better than average, because the annoyance is there every time I put it on. Higher collar would either go over the chin or could be folded down under it. Cerium has a lower collar which doesn't cause this issue. The second issue is that when it rains, the seam where the hood joins the jacket is not sealed. I know this is not supposed to be a waterproof jacket, but of this seam was sealed, it would add to the appeal of the jacket as an outer layer. Cerium LT soaked right through though, so Atom is definitely an improvement in the wet. Lastly, breathability along the sides comes at an expense of wind proofing and the Atom is not suitable as an outer layer in anything stronger than a cold breeze. For this reason I would say Cerium LT could manage colder weather and windier weather, even though the zipper on the Cerium LT doesn't have a flap under it and lets in a fair amount of cold im direct wind.
