Customer Reviews Arc'teryx Atom LT Jacket

I had the old version of this and it was perfect but lacked a drawstring at the bottom so lots of draft. The new version has a drawstring at bottom (yeah) but also a very floppy collar and a weird fit. I'm 5:7 and 122 lbs. The small is tight across the shoulders so sized up to a medium which fits across shoulders but hangs everywhere else. The body of jacket is very wide - you can cinch bottom but lots of extra fabric. On balance I prefer the old version. An awesome jacket if it fits you. I also have the atom SL which is a much better fit - slender in body and cinches at bottom.

Love everything about this jacket. I fit a small perfectly apart from the arms, which are much too short. It forces me to size up to a medium. I tried the hooded version on in the store and cinched the waist - it worked fine. I ordered the size medium of the hoodless version online. When it came - what?!? No waist drawstring, so the whole jacket looks way too big and hangs off my body. Lets a lot of cold air in. Not super pleased. Nothing highlights the difference between the hooded and hoodless version - you'd think they would be the same! Very bizarre. I would do ***** if there was a drawstring at the waist.

I've owned many Arc'teryx jackets and the one i keep going back to is the Atom LT. Great balance of weight and warmth. The only thing i would improve on its design would be in the high way areas maybe using a stronger more abrasion-resistant material.

I adore this light super warm amazing jacket. I have waited two years for other colors. Now you took away maroon and only the gold is new??? No browns or greens or ??? I am so so disappointed. My jacket is in shreds i wear it so much and was just waiting for new colors.

I bought these for my team and I use this for work in oil & gas and industrial work. I cannot speak for sizing because I bought it Large knowing it would be snug. It fits like a glove and is a warm layer for under coveralls and keeps me warm all day without bulk. I wear it under coveralls with a long sleeve poly pro base layer and a t shirt and it has worked well down to -25C. I also pack this for shoulder season hikes as an emergency jacket for ugly surprise storms.

Purchased it as a midlayer alternative to my Alton LT hoody when wearing a helmet. Nice jacket but the "illusion" color is much darker than the picture online. Not as pretty as the Tiya green. Unfortunately I removed the tags before examining it in the day time and now unable to exchange...

Bought first the Gamma but instead of breaking the wind it absorbs all the wind which led me to buy the Atom and return the useless Gamma. The Atom did its job, with its light insulation you won't feel too warm even it's 13 to 15 C degrees and won't feel too cold even between 2 to 8 C degrees during Spring (not sure in winter). I'm satisfied except that the zipper is kind of cheap for the price and the collar could be a little bit fitted.

I have an Atom LT vest and I love it. I'm 55, 6'4" and 190 lbs and the Large fits perfectly. Naturally, I had hoped the Atom LT jacket would work as well. Idaho has cold winters, but also many in-between days in the spring and fall when a lighter jacket is needed. Unfortunately, I found the Large too short in the sleeves and too short in front at the waist. I ordered an XL and found it too big in the torso. I was very disappointed, as generally I've found Arc'teryx products to fit my tall, slim body well. It would have made the perfect light jacket. I'm still looking for an alternative that is as light and good-looking but longer in the sleeves and in the front. I've found some very high-end Arc'teryx jackets that look like they might work for a tall, thin guy, but they're out of my price range.

I love since I got it (5 years ago). It was expensive, but better than everything else around. Used for sailing, mountaineering, climbing, trekking and around the city. Lightweight, super professional midlayer jacket with two minor issues. First is the lack of waistcords, so it is not adjustable, second is the fleece sidepanels in case of static activity, like waiting or fishing.

The jacket is very light and not bulky. It is warm. I own 2 of these jackets.

The Atom Lt is the best light weight puffy that I have ever owned! It's a great insulating layer under a shell. Most of the time when I'm snowboarding or fly fishing in foul weather all I need is this jacket under my waterproof shell. I stay very warm and still have great range of motion in my shoulders and arms. The only drawback to this jacket is it's durability. The outer nylon shell on the Atom albeit lightweight, tears very easily. I have had 2 Atom Light's and both have torn in multiple places while I'm fishing or wearing it with a backpack. My first one was torn by my backpack belt while I was just hiking on a trip in WY, normal abuse, nothing crazy. My newest one tore on a thorn bush the other day while I was coming off the river. Not acceptable! I know this is supposed to be an insulating under layer but it is also a great lightweight outer jacket for cooler weather conditions. If Arc'teryx would just slightly beef up the outer shell on this jacket with some rip stop or heavier gauge nylon it would be the perfect jacket!

Pros: very light but warm, especially thought for outdoor aerobic activities quiet windproof highly moisture resistant in my opinion, as a mid layer, it is far better than fleece, especially in a cold environment Cons Fits a little bit large in the hips

Have worn this mid-layer in 34F weather in mild wind. Under a shell, it was comfortable, but not toasty. Still, when you see how thin and supple it is, I find it amazing. I would never have predicted it. Build quality (mine is from Bangladesh) is great. Zipper is smooth. If not zipped all the way up, the zipper will slide down if you pull on the jacket above the zipper pull. I don't find this bothersome. When I am using it in an active pursuit, it works very well. If I am standing around in the cold, I don't shiver, but I know it's cold out there. If you are cold-blooded, I'd spend the extra bucks on the SV version. It's a 100g fill while the LT is a 60g fill.

Since I haven't seen anyone else on here write about it, I'll start with what I don't like about this jacket: the zipper... If I pull it down partially to get some ventilation, it will generally undo itself most of the way down. I read somewhere that this was done on purpose but I honestly can't figure out why, and I couldn't find reasoning on the Arc'Teryx website. If you don't care about this or don't think you would notice (for instance, my girlfriend who has the same jacket didn't even know that this happened until I asked her about it) then it won't be a big deal, but it is something that customers should be aware of before purchasing - particularly off the internet. My only other qualm and its not important if you try the jacket on is that I find it fits a bit short in the arms for tall people. I'm 6'4" and slim and the large JUST fits my arm length, where the large of the Beta AR fits the length of my arms perfectly. Everything else about this jacket is awesome. Under a hard shell (I have a Beta AR) it is brilliantly warm and can be worn throughout most of the winter. The fleece underarm strips are great at keeping the jacket down when you lift your arms and expelling heat when you're sweaty. The cuffs are the nicest I've seen on any jacket. The best part of in my opinion though is its ability to stay warm when wet. I've been on runs or working outside when its been cold and ended up sweating enough to make the jacket wet all the way through by the time I took it off inside. Amazingly I didn't even notice that it had gotten as wet as it had when outside. Great jacket for active warmth. I would recommend this to anyone looking for a warm mid to outer layer that's VERY lightweight. My girlfriend also loves hers.

The jacket is great. But I had to return it. The jacket runs small across the chest. I am 58 yrs old, 5ft 7inch, 29 in waist, 38 inch chest measured correctly, and weigh about 143 pounds. I am athletically fit. The sizing chart for the size small says 38 chest. When I received the jacket, it was super tight across the chest and under my arm pits. Otherwise, the sleeve length was good and the waist fit well. The size medium size chart says 40 inch chest and it fits well, but the jacket is made for a 34 waist. ? Looks kind of like a skirt it is so big around the waist. I have older Arcteryx jackets which fit me well in size medium. I would encourage Arcteryx to offer a jacket size for fit people. The jackets they are offering now seem to be designed for people large in the middle. Overall. I don't think that my body size is that different vs other fit people my age or younger.

I biught this jacket thinking it could withstand the spring weather of below single digits in SK but did not uphold the expectations. -6 with a breeze and the jacket didn't keep me warm. I would return it if I could. Not worth the price.

The jacket is nice, but the color is much more brown then I was expecting. A little disappointed, but the quality of the jacket is the same great quality I expect from Arcteryx

I recently brought an Atom LT jacket in the new Timelapse colour. The colour is much more green than it looks on the website where it looks more blue so that was a disappointment that what came didn't look like what I ordered based on the website photos. The delivery also came a day later than the UPS notification, I waited in all day only to get another email at 5pm saying it was arriving the next day :( It was also packaged in a box that was probably too small so the jacket has folds/creases that look like they won't drop out. Not a great experience overall, although the jacket is comfortable lightweight and warm

Good light weight jacket for casual wear, do not use for cross country skiing or hiking as this jacket does not breath at all, vigorous activity just builds to a sweaty mess inside the jacket

I've owned many Arc'teryx pieces over the years, and I've generally been very happy with them. I've owned the atom lt jacket for less than four months now, and it is already falling apart. The inner pocket stitching has given way, and now when I put an item in the pocket it falls through the hole, into the insulation of the jacket. This is incredibly frustrating for a brand new jacket, and it makes me question Arc'teryx's manufacturing integrity as they continue to outsource production to countries outside of Canada. I would give this product five stars and recommend it, but I can't do that for a jacket that has issues after minimal urban use. I'm going to contact Arc'teryx directly about the stitching failures, and I'll try to update this review with what their solution is.

I owned this jacket for a couple of years and it performs as advertised. It is one of my favorite , I wore it skiing and hiking and it very comfortable . I wear it almost daily during cold months. jacket is now showing unexpected signs to wear on the collar where it would rub against the neck . Also zipper wont stay zipped up if is done up about chest high . When stretching, the zipper would slide undone. I do expect more for this price range. I did contact Arcteryx and waiting for reply

Great jacket, but over time -- the fabric is starting to peel and the logo came off. I followed the washing directions, but it's not holding up quite as well as I would like. It's still functional though.
