Arc'teryx Cerium LT Hooded Down Jacket - Men's

Don't break down when it's cold outside.

Cerium is the most abundant rare earth metal. It decomposes slowly in cold water and rapidly in hot water. The Arc'teryx Mens' 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 goose down and strategically placed Coreloft insulation keeps you warm during bone-chilling days in the backcountry. 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 with a waterproof shell if you know wet weather is coming. This superlight hooded jacket comes with its own stuff sack so you can easily bring it along on your next ski tour.

  • A light, durable jacket to accompany you on frigid alpine adventures
  • 850-fill goose down is light and compressible
  • Coreloft insulation for areas prone to overheating
  • Lightweight Arato shell with DWR treatment repels moisture
  • Adjustable, insulated StormHood protects head from wind and cold
  • Jacket stuffs into pocket for easy packing
  • Slim fit makes it easy to throw on under a shell

  • Q & A

I’m sure it’s a great jacket

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

I’ve been looking for a down jacket for my winter needs. I have the Atom LT, Patagonia Down Sweater, and North Face thermoball. I got the Cerium LT as a gift and it seems like an amazing jacket. But the price is very high, especially since you can get a Patagonia down sweater for a little more than half the price of this. The Cerium is very warm, but I just don’t have a use for it. My outwear approach is layers, and this jacket is too much in price and warmth. The length is a bit short so I found myself pulling the jacket down throughout the day. I live in the PNW so wet conditions don’t warrant well for down so I don’t find myself wearing this much. I’ll be returning it. I’m sure it’s a great jacket for someone in freezing temps standing outside, but the Patagonia Down sweater is more than enough for my needs at a reduced cost.

Slim Fitting

    Bought the Medium size. I’m 5-11” 155lbs with a 39” chest and 29” waist. Returned because this jacket was a little too tight for me especially when layering. Also, the torso is pretty short. Definitely recommend sizing up, but the sleeve length was perfect so may run longer if you do size up. Wasn’t a fan of the cuffs. The elastic was loose which would allow could air to enter.

    Awesome lightweight, warm jacket

    • Fit: True to size
    • Size Bought: Large

    I've had this coat about 9 months, and I'm extremely happy with it! I've taken it all over, and never had any problems with it whatsoever. It packs up super small, is lightweight, and most importantly is warm! I would absolutely recommend this jacket to anyone looking for a good high quality puffy.

    Stay Warm

    This super warm, light, and durable jacket works great with a waterproof shell like the Alpha SL jacket when moisture is in the forecast; I use it on early morning ski tours and the stuff pocket makes for easy packing when the temperatures rise.

    Best light weight jacket I've ever owned

      Best light weight jacket I've ever owned

      Great warmth, bad durability

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

      I got the jacket, and fell in love with the warmth and lightness of it. However the quality left much to be desired, as down feathers would poke out of the fabric as it slowly lost down.

      Second, after getting caught in a rainstorm while wearing it, the entire jacket started falling apart, fabric just disintegrated and the jacket became unusable. Do not have this jacket on if it starts raining! Arcteryx was of no help in there warranty department so far. I was only offered a discount on a new purchase.

      In my opinion this should not happen if you get caught in the rain!!!.

      Sadly, I have lost a good amount of faith in Arcteryx quality with this piece.

      best all around puffy

        us e this jacket in all weather, perfect weight for all activities

        Go to belay jacket

        • Size Bought: Medium

        Few things I look forward to more than throwing my Cerium on at the top of a skin track on a cold dawn patrol morning. It's super packable and super warm, I don't think there's much more you can ask for from a puffy.

        Top Notch Quality

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

        I bought this from a local gear trade page on Facebook for $125. I feel like I basically stole it. This jacket is very well put together. It replaced my old TNF Summit Series 900 fill coat and its better in every way except for the inability to cinch up the bottom around the waist. (There is no drawcord) Definitely still a very versatile jacket and an indispensable addition to my layering system for backpacking. Medium was perfect for me at 5'8 w/muscular build.

        Great jacket!

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

        This jacket is light and warm. I bought this to replace my old Western Mountaineering Hooded Flash Jacket. They have almost the same amount of down but my old jacket is a little warmer because it is constructed to be more puffy. This jacket is definitely more stylish and form-fitting but the arm-pit section could potentially be a little tight for some. This plus a fleece jacket and a 260 weight icebreaker shirt is enough to keep me warm for the whole winter in New York area both in the city and out in the woods. However, you probably need a rain jacket or soft-shell if it rains. It can hold up in light rain though.

        Love this jacket

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

        I bought this for my husband and here what he has to say about it:

        I am 5'7" 165 and the medium fits perfect. It sits just below the waistline so if you want a longer fit and have longer arms, you may want to size up. This jacket is extremely warm and light. I hiked in 18 degree weather with just a long sleeve base layer and was still a little too warm. Quality is second to none.

        Double Down

        • Familiarity: I've used it several times
        • Fit: Runs small
        • Size Bought: first a Large now an XL

        I love this jacket. The warmth is just insane also has a huge range of motion. I am 5'8 and have a Pennsylvania wrestlers build and I wear Large in everything. Every Arc'teryx jacket, shirt, and layer I own is a size large. I bought this jacket in a large and I looked like a hotdog and only had a T-shirt underneath. In really cold weather I can wear a flannel- Mtn. Hardwear Ghost Whisperer down jacket under my Atom LT under my Alpha SV shell and be completely fine but this coat for me runs small.

        If you are narrow you should be fine but if you are stout order a size up and it will fit like your normal size coat.

        Also, if you are tall you might be wearing a belly shirt. Seems like the coat was intended for a shorter torso. But, I am not tall so hopefully it works for you.

        Just size up

        Is yours roomy/"blousy" in the midsection? What are your other measurements ? Im a 38-39" chest, 32-33" waist and 185 lbs, but have a well developed upper back and bicep area.

        Size chart says I should take a medium, and when I tried it on a medium fit fine everywhere but in the shoulders. I was ok with just a base layer on, but if I added fleece I lost range of movement in the shoulders. Sales person said to go large as a result of that, but while a large fits fine in the shoulders it leaves a lot of room in the mid-section.

        Perfect down jacket? yes

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

        Size:
        I normally wear an XL jacket or shirt and this arcteryx jacket was no exception.

        Fit:
        Jacket has a great athletic style fit to it. Makes even us "soft shaped" individuals look athletic! Does not make you look like a marshmallow. The high loft down means the jacket is quite thin and still warm. Length and sleeves are perfect for me.

        Function:
        I brought this on a 4 day backpack trip to isle royale and it was just what the doctor ordered. It packs down to about half the size of a Nalgene during the day (amazing). At night you can unpack it and be comfortable well below freezing. I wear it in winter with my arcteryx beta at hardshell when the weather really goes south.

        Quality:
        The quality is outstanding. The coat feels great. The zipper feels a little small to be durable, but they have never given me any trouble. If they do, I have a lifetime warranty. The coreloft around the chin, wrists, and pits is brilliant. Depending on the activity you may break a sweat in this; you don't want that sweat to destroy your insulating capabilities. For me I sweat and vent from the wrists and the coreloft holds up great there.

        Cost:
        I can not personally tell you if a $400 jacket is right for you. I got mine cheaper from steep and cheap. I was hesitant at first but have never looked back since I got my hands on the jacket.

        Finally thoughts:
        Do not bring this on backpacking trip hoping it will double as your pillow. 850 fill power down makes for a terrible pillow.

        good jacket,but one broken

          i bought two, but one was broken.

          Perfect for backpacking

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

          This jacket is warm light and simple and that's all I want for an ultralight backpacking piece. The face fabric seems to cut the wind pretty well and the DWR and strategically placed synthetic on the shoulders and cuffs made me more comfortable wearing in light snow or a very light drizzle.

          Im 6 foot 170 lbs and the M fit nice and close. I was able to fit a base layer and a fleece underneath but much more would have been restricting. I wore it in some pretty decent snowy wind and did not notice any heat loss from the waist as other reviewers have mentioned.

          This baby was almost money

            This baby was money as far as quality but was too short in the sleeves and body.... so almost money

            Great product, nearly perfect

            • Size Bought: Small

            Very warm, very weather resistant for weight and great fit. Even with the great fit and hood, there is still a way for cold air to seep in. The waist!! There is no drawcord for the waist! This jacket would be perfect if there was. Cold air gets in from the bottom... This can minimized by filling out the layers beneath, to create a tighter fit (obviously not too tight).

            Everything i was expecting

            • Familiarity: I've put it through the wringer

            I'm not a big skier and when I made the purchase over the winter I was itching to add this super-packable piece of gear to my backpacking kit. Could. Not. Be. Happier. When you're tramping around above 9000 feet it gets pretty cold when the sun goes down, even in July. Luckily this little core keeper will vastly reduce the additional layers you typically feel like adding to your pack. First night dipped under 30 and I did need to couple it with my sleeping bag, but otherwise I was able to sleep soundly in a hammock. Add a light rain jacket on top, though. It is down, after all. Glorious, featherlite, fever-inducing down...

            Everything i was expecting

            I love this jacket so much I bought 2!

            I have the light blue and dark blue. Great warmth and style. and the hoodie doesn't drown me.

            First off, the navy/maroon color is great if you care about that sort of thing. It looks as good with a pair of jeans as it does with a soft shell.

            Second, oh my god warm! I was stuck in a storm high on Aconcagua for 3 days with wind chills far blow zero. I threw my hard shell over this puffy and could not believe that I never got cold when outside my tent. When I was moving on the non-storm days I wore my hard shell and would throw this over the top on breaks to keep in the warmth. The pockets a perfect for warming up the hands and the included stuff sack keeps this thing to minimal size when packed away.

            Third, as you would expect from this brand, it held up well to life on the mountain. No snags and when professionally cleaned it looked as good as the day I bought it. I am 5'11", 190 lbs and the large fits great.
