Customer Reviews Arc'teryx Atom LT Vest

I was looking for a mid layer without sleeves, when I was made aware of this. While I really have not had the weather to use this, in trying on, I like the fit feel of it. I can wear a 150/250 weight wool blend hoody under it, and its perfect. My only complaint is the zipper. When fully zipped to the neck, any movement of my head will cause the zipper to unzip the neck fully. Maybe mine is a defect, and I may request a replacement. Other than that, I like the vest as a minimal mid layer. Its light weight, and would appear to provide good core warmth.

I have this in my pack year round. Winter ski touring as a quick layer for breaks. Summer guiding on the glacier as a mid layer, and in the pack for multipitch climbs during the shoulder seasons. Only beef is that it's not warm enough on those really cold days.... (I also posted the following under the Cerium Lt vest) I'm looking for that quick layer that packs small and provides more warmth. The Thorium AR looks like a perfect candidate to be turned into a hoodless vest. A quick snack and water break on the skin track needs a layer that packs small during those cold days. On the Resort I can whip out the Vest for the chair lift and tuck it away for the leg pumping run down. -The Vest Fan

This Is a fantastic piece of kit, very very versatile. I am always wearing it. Scottish winter it makes a great additional mid layer or even just handy piece to throw over the top of everything when in a rush. I wear it running when its really cold. Climbing in it gives versatile extra warmth and its perfectly ok just wearing around Town. The only reason it does not get five stars is I think the face fabric could be just a little bit tougher. I very quickly put holes in it climbing. Ok I know there is a trade off between weight, packability etc and its not designed specifically as piece of climbing gear but just very slightly tougher could make it perfect in my opinion.

This is a great vest that is almost perfect- warmth without weight, good range of motion, understated styling and good amt of room in pockets. The only problem is the zipper does not stayed zipped in its little "garage." No matter what activity I'm doing, it creeps down 1 or 2 inches. It keeps it from a 5 star rating.

I bought this to use together with my Alpha Comp Hoody. It just gives the extra level of warmth and windprotection. The built quality is what you would expect from Arcteryx, but the fit suffers from the same mistake as on the Fortrez Hoody. It feels like a dress in the lower part, and when there is no strap, you can't do anything about it. Why make a fit for overweight people? I am 192 cm, and weight 85 kg and have it in large.

Great product. Seems rugged and durable, really fits my otherwise rather stocky build, and has a great, sporty look. The zipper goes all the way up, which ensures a good, tight feeling around the neck. Not as "cool" as the Cerium vest, but seems far more usable...

My wife just bought this vest for me in Tobiko, size Large. I am 181lbs, 6ft tall,44in. chest and 34in. waist with broad shoulders. The large has a close core fit. The XL was way too baggy and long. The loose fit would have allowed too much wind into my vest. The Large still gave me enough room to layer my Marmot flannel underneath with a thermal. It was still not too tight. I layered the XL but it was still too baggy in the core area. So far I have not had any problems with warmth. It fits nicely underneath my Alpha SL Hybrid. For other guys out there with a build similar to mine, your choice between Large and XL will come down to personal preference. I don't like my technical gear to fit loose or baggy. I prefer a close to core fit.

I have multiple colours of the previous vest (and jacket). I am short (5 ft 2), and this is a bit long, but the thing I really don't like is the higher collar. It is ok if done up, but open makes me look like I have on a Dracula cape. Sadly, I have had to send them back.

I love my arcteryx 3 jackets plus a gamma MX and endless t shirts and shorts. His was the 1st disappointment I've had with not enough insulation

Have owned this vest for 3 plus years and need to send it in again to have the zipper replaced for the second time. My Atom LT Jacket just blew the zipper as well. Both are XL and no I am not stuffing myself into these. They do not seem to be overly robust as my primary use is that of a 69 year man staying warm and comfy while walking his dog. Both items fall short of their reputation. Real pain having to send in for repairs again. Will eventually replace but not with an LT version.

Great product, although; in the 'old' version the inside of the collar had fleece like material. This version doesn't. It becomes sweaty and dirty on the inside of the collar in just a few days of wearing. Please arcteryx bring back the fleece like materials in collars of all synthetic garments.

The quality of the fabric on the new vests is not as good as older versions of the same product. I had an older Atom LT vest and upgraded to a new one which has bobbled on the back even though I use it in the same way as the my old vest (i.e. hiking, wearing a pack) which never bobbled. The response from Arcteryx was that the product is meant to be used as an insulating layer and you shouldn't use it as an outer layer with a pack on. Seemed a little bizarre given that there are pictures on the website of people wearing packs in the vest, admittedly uploaded by other people. I've got 15+ items of Arcteryx, including the Alpha SV, so I know how good their products normally are hence my disappointment this time. Careful this is not an outer layer.

I bought this vest because I own already a blue cerium vest, and the Atom LT hoody which I both love, and wanted a black vest to accommodate a different outfit. The vest looks great, is very functional with its Napoleon pocket, but it actually fails to deliver core warmth. I think I could comfortably wear this in 80 degree weather without breaking a sweat, e.g., if you need some additional pockets over a t- shirt to carry stuff, but at 30 degrees or below I found it personally useless as a layering piece, unless you use it for strenuous exercising, but for this there are better alternatives. To make it a functional winter piece, the insulation would need to be substantially reinforced.

This vest was great until I found out that it unzips on it's own and makes it difficult to use it outside. I also found that the pocket zippers unzip on their own too. HUGE design flaw especially for the price. My other Arc'teryx items do not do this.
