Unanswered Question

I have atom lt hooded 2011/2012 end I think it was bulid as athletic fit. Now I see this one updated to trim fit. I have several different jackets from Arcteryx but this one (my model from 11/12) has the shortest sleeves and is very wide at the waist. I wonder if something has changed in terms of the cut in the new version?

BC Group-- @5'8, medium build, and ~150lb, I'm wondering if the remaining Medium will run too large on me. Sale price point is very attractive. Are you able to give an estimate, or should I go ahead and purchase/try on at home? Thanks!!

Responded on

Those base specs you and I have a similar build and I would pick up a medium if I sized up. I always suggest however getting your chest and sleeve measurement to get a better idea how a jacket will fit since the lower half of your body has nothing to do with how a jacket will fit but effects your height and weight pretty drastically.

Responded on

Absolutely. I didn't notice if there were sleeve and chest measurements provided in the left column next to the jacket. I'll check now. Thanks! [EDIT] Actually are you able to list the chest and sleeve measurements?

Responded on

The sleeve and chest measurements are located on the size chart (It's the blue 'Size?' link just above the quantity info).

The measurements for a medium are 40 inches for the chest and 34 inches in the sleeve. If you want to try on the medium, email me - ccostley@backcountry.com and I can set up the order for you and hook you up with a return label if you don't like the fit.

I'm 6'1" 175 lbs and I could wear a medium in this jacket but a large fits me better.

Great jacket to throw in the collection. I can see this being used all year round on the east coast. 5-9 165lbs. Large fits perfect as a mid and outer layer.

Awesome jacket!!!

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I had to admit I was a little worried when I got my jacket for it is very light and thin. I bought it to go skiing to Stratton, VT last January, 2014.
The day was terrible outside, 5 F , very windy and snowing but we still went out to sky (or try at least).
I wore a thermal underwear, a mid layer fleece and my Atom LT. It was perfect, I did not get cold at any time neither wet and it was the same next day when we went snowshoeing .
I love this jacket, the S size fits me great and I am a 5'7", 150 Lbs. who likes to wear fit/tailored clothes.
I totally recommend this product.

BC rep please..
I notice the Atom SV is on sale. Wondering why you haven't put all these on sale yet since you are selling the new model now? Wouldn't these all be considered discontinued models? The arc rep said the dealers can choose whether to put on sale or not...

We haven't reached the Spring 2014 price break date yet. Once the price break date is reached the Atom LT will be on sale.

I would like to know if this jacket is waterproof and if it can provide me enough warmth(combined with a mid layer fleece sweter).I am intend to use it in mid mountaineering expeditions and in cold weather conditions.As I will spend the next winter in Northern Europe I would like to know if it is suitable for the purposes I need it for.

Hey Aggelos,

It looks like you just hit us up with the same question on a lot of different jackets. We really want to help you out and find you the perfect jacket for you expedition but it might be a little easier to talk with you directly so that we can discuss and compare the benefits of each jacket you are interested in rather than just spouting specs about each individually.

Good but not great

  • Familiarity: I've put it through the wringer
  • Fit: True to size

A very popular jacket, obviously, given all the reviews here. I've used this jacket quite a bit recently, but only for hiking and not climbing with a helmet. I've found the size of the hood to be very irritating, to the point that I will replace this as soon as I can find something better. Maybe it'll be the next version of this jacket or a different brand altogether.

I'd also like for Arc'teryx to tone down the branding. The logo on the chest is almost comically large. The Aphix hoody that Arc'teryx makes seems to have gotten it right but currently it does not have hood adjustments either.

It really quite baffling that Arc'teryx could not see this would be an issue so I question their testing procedures.

The jacket is good, although not particularly special. It's pretty basic which is kind of what I'm looking for, but I need the basics to be correct.

Responded on

Marius, the slim-fitting "scuba" hood is designed to be worn underneath a helmet as this is a layering piece and not a shell.

The Atom LT is offered in jacket form if the hood doesn't suit your needs.

Interesting feedback on the size of the logo.

Responded on

Stephen, before I wrote my review I did check Arc'tery's website and how they classify this jacket just to make sure I didn't unjustifiably criticize the jacket. I think it's common for people to buy outdoor products that are not designed for what they are using it for. This is particularly common with Arc'teryx. There cannot be that many people doing alpine climbing, for example :-)

Anyway, Arc'teryx put the Atom LT in the "Arc'Teryx Essentials" group which they describe as "highly versatile performance products". Further more, they specifically state the jacket is designed for the following activities: Ski/Snowboard / Ice Climbing / Alpine Climbing / Hiking / Trekking.

So, there's a mismatch here. You don't wear a helmet when hiking or trekking. In fact, perhaps this is an example that you cannot design for all of these things successfully or you may end up compromising on all of them.

I feel Arc'teryx overpromise and under-deliver with this jacket.

I'm aware of the jacket but an insulated hood is great to have.

The takeaway is this: Unless you plan using a helmet this jacket may not be for you.

one of my favorites

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I alternate this jacket with my Mammut down coat depending on the cold chill. This jacket is, hands down, the most versatile piece that I own. It is great for wearing around town, skiing, and layering if needed. It adds just enough warmth without making you boil wants the activities start. It is also ridiculously lite weight and stuffs easily into a bag or pack.

Fit is true to size. I would say it is more standard fit vs the typical Arcteryx athletic trim fit. I am 5'11'' 185lbs and a medium is perfect.

I first purchased the one without the hood and quickly opted to exchange. Definitely worth the cash. If you don't already have one, you should.

Great versatility - excellent quality!

  • Familiarity: I've put it through the wringer
  • Fit: True to size

Purchased this jacket in the Fall. Used it all season for snowboarding from the first day (11/30/13) to the last? (4/27/14) Comfortable over a HUGE temperature range. Really impressed with the Coreloft insulation! Wore it as a stand-alone jacket on spring days, and under a shell on the bitter cold days! Pockets are just right - inside pocket holds your phone, outside pockets large enough for snacks, tools, etc. Cuff design is excellent - simple design that seals out the cold, and slides easily under a shell. Long enough to cover your tail when bending over to buckle in, yet still a nice trim fit. Dries in no time. Stuffs small in your pack at the end of the day! I own(ed)similar pieces from Patagonia, TNF, others, but this is by far my favorite. Worth the money - great colors too!

Perfect mid-layer for the lifts

  • Familiarity: I've put it through the wringer
  • Fit: Runs small

My Atom has become the jacket that I wear almost every day. Comfortable, lightweight, and warm. For me it's fine as a stand-alone jacket except in the dead of winter. In my opinion it packs relatively small considering it's not down. The hood could use a cinch for when you're not wearing a helmet, but when I'm wearing my climbing or snowboard helmet it fits great, especially under the cinched hood of my hardshell. I'm typically size L (I have a Large Alpha SV) but the sleeves and waist were a little short so I went with the XL. The fabric is thin and doesn't last long against sparks, so don't be stupid like me and wear it around a campfire!

Very very close to perfect

  • Gender: Male
  • Familiarity: I've used it several times
  • Fit: True to size

This is a great, almost perfect, mid layer for very cold temps, or a good outer jacket during spring/fall. I come from using a minimal down sweater almost daily except during the height of summer. In Spring or Fall this jacket works great as an outer jacket. The breathing side panels do make a difference compared to the down sweater I was wearing, the Atom being less clammy feeling. Together with the less 'sticky' outer fabric this just makes me that little bit more comfortable.

Had some mild rain and DWR works great for now. Main reason for synthetic for me is it will be easier to wear under a shell and not worry about it getting compressed or wet as much as with a ultra light high fill power down shirt.

I'm 184cm and 72Kg (6.1/160) and I'm often in between a Medium and Large due to broad shoulders. Got a Medium and it fits great. If you want to layer a lot under it, or you like a looser fit, you would probably like a Large.

I have a Atom SV (also Medium) and the two are sized to be worn together (the LT with the tighter fit, the SV looser) so no need to adjust sizing if you are thinking about going that route.

The hood is not as bad for me as for some other people. I've been in stormy winds twice and although the hood wasn't shut tight and let in air, it did stay securely on my head. I feel a cinch cord in a newer model would be well worth the weight though and really make the Atom LT 100% perfect for me. The hood on the Atom SV is perfectly adjustable with the cinch cords on the sides and in the back.

The remarks about the cuffs are not exaggerated. It's a sign of good design when you get something you never knew you needed. Arc'teryx is expensive but their attention to detail, their fabrics, and their cut (the fit) is the best there is.

Responded on

I'm about the same size. 6'1" 160. Even among clothes that are supposedly designed for active people, it's tough finding upper body wear that's long enough, but doesn't look like a tent in the waist area. Do you find the sleeves plenty long enough in the Medium?

Does the 2014 model have the hood cinch...

Does the 2014 model have the hood cinch cord like the LEAF series? It would be nice if BC would carry the LEAF series. Thanks.

Responded on

I haven't seen it myself, but heard from two people that went to a trade show that it would have a hood adjustment for 2014.
I thought in the back, not on the sides but can be mistaken.
Although I don't think the hood is as bad as a lot of people seem to do, I do think either way of hood adjustment would be a definite improvement and make this hoody perfect.

I have the 2014 LEAF Atom LT Hoody in Wolf, and can tell you that it has a drawstring identical to the Cerium LT Hoody. I believe the drawstring hood comes to civilian versions in Fall 2014

I bought alt yesterday and it's not the new version with a hood cinch yet....I will prob return mine if the hood cinch model comes out in the next month.

Responded on

Confirmed with Arc customer service today, they are making changes for fall of this year but they wouldn't say what was being changed.

Responded on

I would honestly just get the LEAF. It is virtually the same product as the 2013 model except they have the bigger pockets and much needed hood cinch. From an aesthetic perspective, I actually like the LEAF more as it has a non-reflective logo that just kind of blends in with the rest of the black jacket. Then again, some people love the color variety. It's really your call. I have a 2014 Atom LT LEAF and I love it. I'm 6'0, 160 lbs, I got a Medium and it fits me perfectly. I can even put a nice thin fleece underneath for when it gets a little chilly out.

Responded on

Is the fit exactly the same for the standard and the LEAF version?

Sizing

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

Great jacket. Everything has already been said about the features. 5'11" 170lbs and I wear a large. The medium felt too tight for me around my neck and too short in the front. If I was getting this jacket solely for the technical aspect the medium might have been a better choice, but for me it will be used for around town also. Call me vein or self conscious, but it's kind of lame when your mother asks if you are wearing your wife's jacket because of the fit.

Packs tight

Packs tight

In a recent mountain hiking trip where I started at a point where temps were around 74-F and ended at below 50-F I carried this jacket packed in the pouch it comes with. As such it is about the size of a Nalgene liter bottle. It is light so it didn't bounce much as attached by a small belt on my Lowepro camera belt bag. Carrying it that way makes it instantly ready for when I need it and I didn't have to dig in my pack for it. At night when it was close to freezing I wore only a shirt over a thermal top under this jacket and that's what wore to sleep in a tropical grade sleeping bag.

(Btw, this is my second review. I'm the guy who sew the edges of the hood so it fits more neatly over my head.)

Great Mid Layer, great fit w/Beta AR

  • Familiarity: I've used it several times
  • Fit: True to size

I tried out several mid layer options by Arc'teryx including the Nuclei and Atom SV, neither was a good fit. The Atom LT is extremely light and a great mid layer that I wear over a fleece on colder days.

Best light insulated jacket ever!

  • Familiarity: I've put it through the wringer
  • Fit: True to size

one of my favorite jackets - use it all the time! Perfect fit, really light and packable, comes with a bomber DWR treatment that lasted over a year, so nice fit that you don't notice you have it on. Really good breathing when used as a middle layer under a shell.

Great jacket, hood too big though

  • Familiarity: I've used it several times
  • Fit: True to size

I own at least 18 pieces of jackets/shells accumulated over time and this is my third Arcteryx coat (with a fourth one on the way; I have an eye for quality, an expensive vice I must admit). It quickly became my favorite for its fit, light weight, and especially packability. It is flexible all-around as I can mix and match with just about any sweater or even down jackets in my closet to be warmer if needed. I can put a shell on if it gets too wet.

One complaint is that the hood is too big for my head and "de-hood" easily when in use especially when it is windy. So I pinched the hood opening by about and inch on both sides by sewing the edges as you see in the picture. It is a solution that works for me quite well. It took some effort, but because of that I like this jacket more.
