Don't break down when it's cold outside.
Cerium is the most abundant rare earth metal, and it decomposes slowly in cold water and rapidly in hot water. The Arc'teryx Men's Cerium LT Hooded Down Jacket is not quite as prevalent as its namesake, but it does slow your decomposition in cold weather. The combination of 850-fill European goose down and strategically placed Coreloft insulation keeps you warm whether you wear the Cerium alone or under a hardshell when you're confronted with a winter tempest most storm chasers avoid.
Big numbers are fun when it comes to betting odds and down insulation. A higher fill-power down, like the 850-fill used in the Cerium, refers to how much space a single ounce of down occupies. The more space taken up by the down means more air is trapped between the fibers. Trapped air creates a barrier between warm air from your body and cold air in the environment, so you stay warm when it's cold outside. Taking this logic one step further, if one ounce of a certain down takes up more space than a different type of down, it stands to reason you'll need less of the 'bigger' down to keep you warm, thus reducing the weight of your jacket. In essence, this jacket's high down fill makes it both light and warm.
Since down doesn't maintain its warmth when it gets wet, the folks at Arc'teryx placed synthetic insulation in the spots that are most likely to get a bit damp. Still, while Coreloft insulation does resist moisture better than down, and an ominous drizzle won't leave you a cold, soaking mess, it's best to pair this jacket with a waterproof shell if you know stormy weather is coming. This superlight hooded jacket comes with its own stuff sack so you can easily bring it along and so your pack stays organized. The same 850-fill down fills the low-profile StormHood so your melon stays warm. (Mom was right—if you keep your head covered, you'll stay warmer.) Two zippered hand pockets hold your keys and phone, trail map and candy, or your partner's ID and lip balm.

Arc'teryx – Men's Cerium LT Hoody
Streamlined, lightweight down hoody filled with 850 white goose down. This backcountry specialist hoody is intended primarily as a mid layer in cool, dry conditions.
Outstanding jacket for freezing temps
This jacket is very windproof and super lofty. This down layer insulates very well but does not restrict your mobility. I took a couple good falls out on the mountain and it still kept me warm and dry. This jacket is not intended to be waterproof however, it is very durable and tough. This jacket is perfect for riding on powder or on the trail.

Brandon Carlile with Arcteryx showing off the new Cerium LT jacket.
which size i can choose for Arc'teryx Cerium LT Hooded Down Jacket - Men's , my weight :143.3lb and height: 67 in
Hey Elina, As it has a more trim fit, i'd recommend going with a medium for it to be most comfortably fitting for you! If you have any other questions or anything I can do for you, feel free to reach me at email@example.com or my direct line 801.204.4547! Cheers, Connor
Does anyone know which is warmer between this jacket and the Patagonia Down Sweater Hoody? I realize warmth is somewhat subjective, but I'm just curious if there is any measurable difference between the two aside from weight.
The reviewers at outdoor gear lab said that the Patagonia down sweater is slightly warmer, and they're pretty detailed in their reviews. I'd check em out to see which one is best for you. http://www.outdoorgearlab.com/Down-Jacket-Reviews/Patagonia-Down-Sweater-Hoody
Cerium LT is 850 down fill at 275g total, and Down Hoody is 800 down fill at 428g total, 56% heavier. Despite a slightly less fill ratio, the Patagonia will have significantly more fill insulation and will keep you a notch warmer. These type of jackets don't breath well unless they have some sort of hybrid breathable panels, so I always say get the warmest you can comfortably carry, which would be the Patagonia. Only reason to get the Arc'teryx would be if you'll be carrying it frequently in a pack and need to absolutely pinch grams.
Which by the way, Backcountry.com it's time you list Grams on all your products...the entire world and most manufactures use only Grams, yet you still don't have it...
I'm not sure Snorske has their info correct........this jacket claims total overall weight of 9.7 oz and stats 3.35oz of down fill weight. 9.7 x28 grams =271.6 grams so Snorske claim of 275 grams is not the weight of the down or a reflection of the warmth. So according to my research and numbers thats but 93.8 grams of actual down fill. In comparison TNF Super Diez is a 900 fill down with 130 grams of actual down fill.
Which jacket is warmer? The Arc'teryx Cerium LT or the Arc'teryx Thorium AR?
For the most part the jackets will be fairly similar but looking into the details, here is a break down of the finer points:
Thorium AR (down): 750
Cerium LT (down): 850
Thorium AR (fill weight): 3.5oz
Cerium LT (fill weight): 3.35oz
Thorium AR (Synthetic insulation): 80/140grams
Cerium LT (Synthetic insulation): 80/100grams
So after looking at the breakdown of the insulationthe Thorium will have more insulation in it but in the case of the down it'll be slightly lower quality (but really 850 to 750 isn't a huge difference).
I'd look at how you want the jacket to fit since the Thorium AR is an "athletic" fit and the Cerium LT is going to be a snugger fit due to it being a "trim" fit.
Shoot me an email anytime you have questions!
Thorium has more of a square cut and the Cerium has more of a trim fit. The Arc store rep had the same basic take as Jared (gear Expert) above did that they are more or less the same warmth, so it's more or less the cut you prefer.
I'm 185 lbs 5'11 and like a snug coat and the medium in the thorium was good for me, but for the Cerium i'm going to go with the large. hope that helps
What is the best size for me - I've heard the Cerium LT is a trim fit. This would be worn as a base layer. I'm 5'8", 140lbs, 37-38" chest with 31" waist and hips. I have an Arcteryx Alpha SV size small which has plenty of room for layering up under it but as I understand it the Cerium LT is a whole other fit altogether. Thanks
Honestly i think you should look at the small. I am similar size (a bit larger) and went with the medium initially and found that the jacket just wasn't that warm. Wind would blow right up the back. With the small, i didn't lose any freedom of movement, but gained a lot of warmth as the hem of the jacket worked the way it was designed.
I'm 5'10 and my current weight is 180 I want to layer up under this jacket for NYC winters what's your best recommendation for a comfortable fit medium or large?
Since it has a trim fit I would get the large to make it comfortable. You could probably fit into a medium but, it might be snug especially when you layer underneath it. What is your chest measurement? That is a really good indicator of how the jacket will fit.
If you have anymore questions feel free to send me an email or call!
Just tried on the Medium and the Large at the store. I'm basically the same dimensions as you and the Large fit perfectly over an undershirt and a regular fit button up shirt. The medium was form fitting, but a bit tight in the sleeves.
I also tried on the Thorium AR Down which is a more of a regular fit/square cut and the Medium version of that was more roomy than the Large in the Cerium.
Are these made in China? I just got one on ebay for a deal and it says "Made in China." However, a search of the web shows that apparently a lot of Arcteryx goods are made in China. I just want to confirm as I'm returning the ebay purchase and planning to re-buy the jacket here, assuming it's not made in China. (And assuming the size is right. Everything I read about these jackets said they run small so I bought a large, but it's huge on me.)
It is made in China, but that doesn't mean anything. As I know this jacket definitely has counterfeit in color nighthawk and black. I suggest you to purchase from authenticated sellers.
Hello, I'm torn between getting this jacket and L.L. Bean's Ultralight 850 Down Hooded Jacket. Does anyone have experience with both so that they can compare them together?
Haven't tried this hoodie, but I can tell you that the Bean hoodie is a little gappy in the middle, and the hood - although very good - isn't adjustable. Also - when last I checked, it wasn't available until JUNE!
I just received my LL Bean Ultralight and love it (was told it was back ordered to June 1). Very light, has Pertex shell, inside skins pocket and zip pocket that the whole jacket packs into and 3 outside zippered pockets. Got it on sale for about $170. I am 6'1, 195 and fit nicely in a Medium Tall. Nice fit. We'll see how it holds up but has a lot of features for the $.
Which is warmer, Cerium LT or Western Mountaineering Flash XR? Also, which is smaller when compressed?
I will be wearing one of these under a softshell jacket during multi-day alpine climbing in winter Alps.
The WM Flash XR will be warmer it has more down in it. The Cerium LT will compress more due to less down. Either or will be fine, Id say under a soft shell you are just fine with the Cerium LT.
I'll ask what's gonna be warmer n last longer this or the Patagonia down sweater
Patagonia Down sweater will be warmer and last longer but, it is not as performance oriented as the Cerium LT. The Cerium LT is meant for light, fast moving through the mountains where the Down Sweater has more of an all around purpose.
What is the center back length of a medium?
Hey everyone--quick question.
I have a hard shell (barely insulated) and a solid fleece. I was hoping to get a light-weight down jacket to layer with, or wear alone conditions permitting. I hike (nothing too intense) 1-2x/month when I can get free. I'm looking to buy a down jacket that I can use to stay warm up in Boston, both when I'm just getting around and also when I get to hike.
My question is this: is there a reason to get, or not get, this jacket with a hood? I don't really imagine too many times where I'd use the hood, but I'm not really sure. The price difference isn't a big deal if there's something I'm missing. Ideally, I'd like to wear this with a shirt or light baselayer to get around, so maybe having a hood around helps in case it get's wet, but then, I would want a shell regardless for the down, no?
Yes if it is raining you will want a shell. It's a personal preference but I tend to find most people like hoodless for a mid layer piece and the hood when wearing as a stand alone. However, depending on your shell a hood will not work on certain types jackets necks. I personally only have hooded pieces but all of my shells have storm hoods.
If you want to discuss this or any other down jacket we carry, you can hit me up at 1-800-409-4502 ext 4420 or firstname.lastname@example.org
I have a Cerium LT hoodie, do you have a shell you recommend to pair it with?
I'd say the beta ar
Im 5'6 and 160lb with a chest size of 39"....
Im 5'6 and 160lb with a chest size of 39". I'm guessing the medium would suit, but I'm considering the small due to not wanting excessive length in the arms. Any recommendations?
The Arc'teryx Cerium LT is based on a trim fit block. I would recommend the medium as I think a small would be too tight through the chest area. The difference in sleeve length is only 1", so you should be GTG.

I have an Atom SV but I am after something a little warmer for an insulation layer.
Will the Thorium be warmer than the Atom SV?
My Atom SV, in real time use, is warmer than the Cerium LT Hoody. The Atom's construction gives it better wind protection, as does the addition of the hem drawcord.
Anyone using this with a pack? I know its...
Anyone using this with a pack? I know its designed as a mid layer, but anyone have any wierdeness where the straps of the pack rub? just curious
I haven't noticed a problem with packs on my bike commute.
I am assuming by "wierdness" you are referring to fast wear in the shoulder area. I typically wear my Cerium as an outer layer rather than a midlayer, and often with a decent sized pack. While the Cerium's fabric is necessarily light weight I have been impressed with out how sturdy it is. No signs of wear to the shoulders or anywhere else for that matter.
If someone is concerned about durability I would probably favor choosing the Thorium which has a 40D face farbic compared to 20D in the Cerium. The increased weight is not too substantial from Cerium to Thorium. But again, I have not seen any issues with durability in the Cerium anyway.
this jacket is so light i find it hard to...
this jacket is so light i find it hard to believe it will keep me warm so let see how it works: it's about 20 outside right now with a very slight windchill to 17. Having gone out for a tester walk around the block, in just a Tee, i can feel some air get in from the cuffs since it's only elastic. i can also say this jacket lets the NorthEast winter cut right through. If i had a warmer base layer, maybe it'd be OK.
I cannot seem to find something that works - everything seems to be Light Weight. I tried the Marmot Guide Hoody but didn't find it warm either. What's a good jacket between this ArcTeryx & the LLBean Ascent with Windstopper?
You have a fantastic jacket on your hands there but it is important to recognize its intended purpose and potential limitations. As the LT in the name denotes, this is designed to be a high quality lightweight down jacket. You can wear it as an outer layer during clement conditions, but in harsher wind and snow I would definitely layer it under an outer shell. This jacket does not claim to have any sort of windblocking membrane. If you are looking for a down jacket that can stand alone in the harshest of conditions I would suggest the Arc'teryx Therme Parka.
Hi PL, I think your best bet is going to be something that has both baffled down and a wind-blocking exterior. The Cerium is quilted, meaning that the horizontal pockets that hold the down are sewn through both sides--a baffled down coat uses what essentially is mosquito netting to suspend the down on the inside and create a jacket without any cold spots. I would recommend something like the Marmot Shadow, which is warm, baffled, windproof, and comfy too. Check it out here:
Hope this helps!
i think the shadow is a great recommendation, but i would like to make a different point. unless you already have a great waterproof jacket, you can save money and buy a shell to layer over your down jacket on wet and windy days, and wear alone with the mercury isn't too low. also, it doesn't sound like you'd like any light weight insulated jackets, so look for jackets in the 2 pound and up range to get lots of warmth. the trade off is they'll be bulkier.
I have been wearing my Cerium in 14 degree weather with just a t-shirt on and had no issues. its So warm.

6'0" 165lbs, thin and athletic build. Tried the Patagonia down sweater in medium and felt I needed 30 more lbs on my chest to fill out the empty space. Jacket length and arm length were perfect though....going to return and look for something better fitting.
Recommend a medium for this jacket?
Medium 100%. This is trim fit.
how about the length? website doesn't give me any detail on torso length.
The official length from Arc'Teryx simply states "hip length" but I have measure it at 26" and sleeve length at 33". I would add to Tester's answer that I am able to fit a medium and a large very well, and I would also recommend the medium for you.
is the sleeve length measure from center back?
Would it be safe to say that a large cerium...
Would it be safe to say that a large cerium lt should fit like a medium thorium ar? I am 5"10 175lbs and my shoulders and chest are broad. I tried the beta lt in medium and it was too tight around the back and shoulders... Should I size up in a cerium to be comfortable?
I'm 5'11 175 and the large fits the best in the Cerium. Great jacket as a mid layer during cold weather with your shell.
Awesome, just ordered it and we shall see. I like the thorium a lot but if this one is lighter I may swap it out and keep the cerium
I don't mean to be redundant, but I think it may help other Backcountry customers interested in the Arc'Teryx down jackets to know that the Cerium LT is built according to Arc's Trim fit while the Thorium AR is built according to Arc's athletic fit which is just slightly more generous. I am close to Scott in size and can affirm that a large should fit you well in the Cerium while a medium would fit you the same in the Thorium.
I'm 5'9" 165 pretty athletic and the medium fits me great. If you're planning on wearing something heavy beneath though, definitely size up.
I just received my cerium jacket. I'm...
I just received my cerium jacket. I'm 6'0" 195 lbs and purchased the large. It fits well EXCEPT I find the armpits to be uncomfortable because of the super athletic fit - it feels like you have a material bunched up under your arm when your harms are hanging down to your side. Has anyone else noticed this? Does it "stretch" or give a little over time to be less noticeable? At the moment, this is a deal breaker given the cost of the jacket - I want it to fit and feel well for $275. Thanks in advance.
6'2" 200 pounds, I also have a Large. I have noticed the same thing, though I have not personally found it an annoyance. I do not think it will give over time (hasn't on mine). I would offer that the Arc's very athletic cut makes it more difficult for some folks to find a good fit with this jacket, body-type dependent of course.
Between the Arc'Teryx Cerium LT hoodie and...
Between the Arc'Teryx Cerium LT hoodie and Feathered Friends Daybreak hoodie, which jacket would be the better choice?
If you are counting your bucks, the the Feathered friends is quite less expansive.
However, i believe Arc'Terix is more experienced at making down jackets. The Arc'Terix It's a 850 fill down, The feathered friends is supposed to be 900 fill, however people have been reporting that some of them are actually 850 fill...I don't think it does really matter at this level.
The Arc'Terix has also a nicer look.
I would go for the Arc'Terix
If I'm not mistaken this is actually Arc first down jackets, the Cerium and Thorium. FF has been in business since the 70's making down products, http://featheredfriends.com/about/.
Just to make sure you have all the info you need LaughingH20.
hegaveitall is correct; in no way is Arc'teryx more experienced with down garments, the Thorium and Cerium are Arc's first efforts. That being said, both jackets are superb.
Feathered Friends has a near-impeccable reputation for their quality and warmth. I would like to see exactly where "people are reporting" they use 850 instead in the Daybreak, that sounds like hooey to me.
The Cerium has 97g of down vs. 89.5 for the Feathered Friends. Given the $75 price difference, the choice is yours.
Get the Arcteryx.
Feathered Friends makes great sleeping bags , but in my experience, all of their clothing is cut really strange and runs about 3 sizes small. You might like it if you are a really small person with no torso, but you should probably try one on first.
You can only tell so much by comparing specifications.
Both jackets will use top-notch materials.
The arcteryx piece will be perfectly cut and true to size.
However, the fit of the Feathered Friends jacket might be more "esoteric" so you should probably try it before you buy it (or just get the arcteryx, which is a sure thing).
Hope this helps.
Order both, try them on, return one. Specs talk, but fit can scream...yes? And you wouldn't miss that extra $75 in six months, let alone in however many years the thing lasts.
