Hi all, which size would suit me best? M or L? I am 5'10", 185lbs athletic build... 43" chest and 33" waist. Thank you in advance for your time. Cheers!
I'm having trouble deciding whether or not...
I'm having trouble deciding whether or not to get the version with the hood or without the hood - does having the hood cause any problems when you add another outer layer on top of it? Would you need to have both hoods up or can you have the hood on the Atom LT down and the hood on an outer layer up?
I've always found that a layer with a hood is a pain in the butt. In a down item like this it is easier to stuff it down. But, if this is mainly for layering, bag the hood option.
I've used the Hood and jacket version of this. I find it depends a bit on the type of hood on your shell. If it's a storm hood, where the collar and hood are one, the Atom LT hoody works great. I give it a couple inward rolls and it forms a soft gasket and doesn't choke me. For drop hoods where the hood and collar are seperate, a jacket is more comfy.
I prefer the hood for wearing the Atom on it's own in more mild weather or when I'm moving in chilly weather or when it's snowing.
Take note this is a synthetic insulator not down, as indicated by JP.
Atom LT Hoody
You can even skin in this when it's cold out.
Blue Ray color
Do yourself a favor and get the hooded version!
This is a great jacket, and I've tried all 3 versions. The pullover doesn't have pockets, and the non hoody doesn't have a drawcord hem... this one has it all. I was skeptical about the hood at first, but once you try it on, its like the hood isn't even there until you wear it up. The jacket fits great and weighs nothing. It layers perfectly under Alpha shells of the same size, so my SV and SL both work as great outer layers. I tried the SV version of this jacket, but found the 100 gram core loft to be a bit much when I mostly use it for layering anyway. I highly recommend this jacket, and its worth ever penny. I got the Lichen color on sale, and it might be the only time I could tolerate that color.

I just bought a mh dry stein elite. Medium size outer shell.... I am 5'9" and weight is160 with32 in waist.... Planning to do PCT which mid layer would you suggest? I plan on merino as 1st layer..
the Atom LT would be a great choice for a mid-layer and you'll be able to wear it on it's own in a huge range of conditions as well. If the medium jacket fits you well you could do the same here. For a more close fit the small would also fit you.
Just right, love it
Live in UK. Have a Kappa SV hoody for real cold and being inactive outdoors. Needed something milder for slightly warmer days and for when popping in and out of cold. Have worn this jacket for a few weeks now and its so comfortable, light and seems to regulate my temperature brilliantly. Walked the other day when it was 3 deg (38??) with t shirt underneath and was plenty warm enough. Not toasty, just right. Sides do leak a little wind/warmth but as a hot person find this nice.
As a sizing guide. I am 5'10, 175 lbs, 33' waist, 40 chest and 32.5' sleeve and Medium fit perfectly with just a t shirt underneath. possible to wear 100wt fleece underneath. A little snug under the arm, but due to softness and slight stretch to the jacket, not a problem and doesn't restrict movement. Hope this helps
N.B. I often have a problem with arms on jackets being too long. Tried on lots of softshells that felt like cardboard and looked daft in the arm. The atom (34' sleeve MED) is so soft that arms being too long is not even noticeable. Throw your fleece/softshell combination away and get one of these.
Only doubt is how durable face material would be if roughed up alot.
The Atom LT is a great jacket and a really superb layering tool. Arc'teryx proves once again that their stuff really can't be beat, as this has quickly became one of my favorite layers I've owned. The athletic fit really helps with fitting under a shell or heavier insulating layer, as well as having a better fit for those of us with slimmer builds. Synthetic insulation is also key for the Pacific NW, performs really well under the wet conditions that you find around here.
I'm 5'8" with a slim build and a small fits perfect.

I usually wear Marmot fleece jacket which is polartec 200wt under Stingray jacket with just a thin base layer. I am usually comfortable or even a little too hot except in windy conditions. How is the warmth in Atom LT compared to the Marmot fleece jacket and is it much better in windy conditions in terms of wind proof? How about breathability? Should I go for Atom SV?
The Atom LT Hoody is about equivalent in warmth to a 200 wt. fleece, but with much less weight and bulk. It does have a wind/weather resistant face fabric, and a smooth fleece under the arms, which give it a much broader usability than any regular fleece. The fleece underarms will let a bit of wind come through, but helps keep the breathability good. A couple other things I like about this (I've basically retired my fleece for layering) smooth face fabric slides under shells, especially Stingray with it's fuzzy inside, and it's super packable if you don't need the insulation; about 1/3 the size of a 200wt fleece when packed. The Atom SV is more of a wear alone insulator in warmth and fit.
Different Material/Side Venting
Here is a picture of the fleecy side venting material, which exists from just below the armpit (down the arm) to the waist... Its not shown in factory photos and not clear to everyone that this exists on this jacket...
Hi I am a 6" and 74kg guy. Should I order...
Hi I am a 6" and 74kg guy. Should I order XL or L size? How much does this cost to ship to Korea?
I would size up to an XL if you are unsure and for the extra coverage. Arc'teryx usually slims their jackets down and so you shouldn't have too much of an issue with excess material.
As an all around layer I would recommend the Large for you. You may find the XL a little too wide in the shoulders and torso. This is meant to fit closer to the body. I am 1" shorter and the same weight and can fit a medium or large. The mediums tend to fit a bit too short for my liking. The arms are plenty long and the side panels have some stretch to allow for movement.
Hope this helps
As for shipping you should check with Backcountry. They have Agreements with some brands like Arcteryx and cannot ship to some countries. Check out the list
This can only be shipped in the US.
I'm 6'2", 75kgs and a medium fits me great. Enough room under it for a merino base later, and it's not tight or restrictive at all.
Debating between the XL and XXL... How...
Debating between the XL and XXL... How wide is the Atom LT in XL and/or XXL *across* the chest?
It'd be useful in comparing the Atom LT to some garments I already own or can try on- Patagonia Nano Puff (XL, XXL), Arc'teryx Gamma AR (XL) and Gamma LT (XXL). Thanks!
It depends on how much you weigh and your height. You can check the sizing chart up by the size option drop down box. For sizing on the Atom LT Hoody, it's sized to be a layering piece, so will fit closer than a Gamma AR. Your size choice will depend on if you plan to use it as an light outerwear jacket or as a midlayer insulator, and your preference on fit.
@Brandon- thanks for the quick reply!
That's why I'm curious about the chest width of the Atom LT in XL or XXL with the garment laying flat- it'd allow me to compare it other garments.
I plan to use this as light outerwear and as a mid layer. My shells are pretty roomy.
The way Arc'teryx usually fits, I'm a 1.5 XL. :P Stuff on the snug side is good at XXL, stuff on the relaxed/casual side (Apache AR) is good at XL. My main concern is fit around the chest- when Arc'teryx XXL is too big, it's usually way too big around the upper chest.
looking to replace my patagonia micropuff...
looking to replace my patagonia micropuff hooded jacket. any thoughts on the best way to go with an atom; lt or sv for a comparable warmth. i'm 6'1" and 192#'s and wear a large in the micropuff. any recomendations for size in an lt.
From what I've read this is cut to be a mid-layer so a Large would probably work well for you. I'm a similar size.
The Atom SV is your best bet to replace the Micropuff. The Micropuff has 100g of Primaloft vs. the Atom SV with 100g of Coreloft. Coreloft and Primaloft are roughly similar in terms of warmth (there are many variables and details we could get into but that's the simple answer). The Atom LT has 60g of Coreloft which is comparable to the Nanopuff (60g of Primaloft). For an in-between option, you can try the Mountain Hardwear Compressor which has 80g of Primaloft.
Mads you are not quite right. The Nanopuff has 60g of insulation, same as the LT.
Sorry joomington, but Mads is right on- the Micro Puff's 100g Primaloft is going to be much warmer than the Atom LT's 60g Coreloft. The Atom SV is going to be closer than the LT to the warmth of the Micro Puff.
joomington- just FYI, the Micro Puff != Nano Puff. As an aside, the Nano Puff w/ 60g Primaloft is warmer than the Atom LT w/ 60g Coreloft, due to the stretch panels on the Atom LT. That's by design- the Atom LT is not a belay jacket or camp midlayer, but an active/semi-active midlayer.
Sorry Mads and Rev, you are quite right. I was getting confused between the Micro and Nano Puffs. The Micro Puff doesn't seem to appear on the Patagonia website anymore. Also am I right in assuming that these 60g and 100g ratings are grams per square meter?
light and fluffy
it is fitted so you wont get hung up when out and about, climbing, skiing, hiking....... compresses down pretty small, not as small as down feathers but gets pretty small. It is also just waterproof enough to get the jobs done! I wouldn't hang out at a hurricane in it but works well for warmth in lite rain.
how warm is this jacket? with a shell can...
how warm is this jacket? with a shell can you wear this, a tee, and a shell in 0 degrees?
Probably not. It's about the same warmth as a mid-weight fleece. If you are walking around in 0 degree weather (assume you mean Fahrenheit), this will not be warm enough. In my experience, I can wear this jacket into the 30's (when I am standing still) or into the single digits (when I am working out vigorously).
Look at the ATOM SV jacket- it is much warmer. It uses a heavier weight primaloft insulation (100 grams compared to 70 grams) and does not have the size fleece panels. it will suit your needs. If you want something warmer still, you can move up to the Kappa series of jackets which use 133gms on the AR and 200 on the SV versions).
This is my favorite piece of Arc'teryx gear. Comfortable, lightweight, very packable and pretty warm for such a light jacket. Wind resistance is surprisingly strong. I wear this thing ALL the time. The stretch fleece side panels are really nice, and make it feel more like a hoody than a jacket. As always the Arc'teryx articulation is the best and there is no ride up in the sleeves or waist. The stretch cuffs are a nice touch also. If you are considering buying this, you will not be disappointed. Unless, of course, you don't like high quality top of the line products, in which case you would likely be disappointed. Worth every penny!

Great Packable Jacket
Another great jacket from Arc'teryx. Definitely not a jacket to be worn alone when your excursion becomes abrasive; I always have to keep in mind the light face fabric. Awesome jacket to pack as a layering piece, packs down very small... One thing to note is that under each arm, from about the elbow to the waist the fabric is replaced by a stretchy fleece type fabric... none of the pics nor description show this. I find this great for heavy touring/sweating as its almost like direct venting. But when the jacket is worn alone, you must keep your arms down to prevent being chilled to much. I am 6'1" 220lbs and the XL is athletic fit.
Atom Lt on route
The Atom Lt makes a soft shell redundant in most winter climbing scenarios. Incredible jacket if used in the right place.
More detailed review here:
I'm 6'2'' and 175, should I go with M or...
I'm 6'2'' and 175, should I go with M or L? I'd be using this as stand alone or under my Stinger shell. My Stinger is M, as I do not like to wear tents.
I am also thinking between this and non-hooded version - does anyone has experience how the hood fits under Stinger (or similar) shell?
Yes, Large. I've used both alone and layered. I prefer the hooded one in general, and the hood can be rolled inward and forms a nice gasket under the neck of a shell. While this works better with storm hoods (not the type on the Stinger) it didn't give me the feeling of being strangled. I use the hood often when I wear the Atom LT by itself.
Large should be good.
Updated review for this jacket
The more I wear this jacket the more I love it! I already wrote a review but the more I wear this thing the harder I find to take it off. It works in such a wide range of weather and feels like it's not there half of the time. Blocked some precip today, but had to bust out the Theta AR when it got really bad. Also I found something cool today, if you fold the hood in to the back of the neck when not in use, it provides a LOT of warmth for your neck. The cut and fit is perfect, you won't believe how warm and light this jacket is. A+ can't wait for more colors for I will get another in the future.
