Cerium LT Hooded Down Jacket

Layer the Arc'teryx Mens' Cerium LT Hooded Down Jacket under your shell when you head out for a backcountry tour on a crisp, cold morning, or use it as an outer layer for chilly fall hikes. 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.

  • Light, durable midlayer for cool, dry backcountry conditions
  • 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

Better options

    I got this jacket at a heavy discount and decided to return it still as I decided there were better options out there. For the full price, I couldn’t justify recommending this item to others. If I could I would give it a 2.5 rather than just a two, because I feel like others might find value in it that I don’t. I tested it during one weekend backpacking above 10k feet in the Sierras and have friends with the jacket. They agree that durability is an issue. The jacket is meant to be a very lightweight puffy that is very pckable and that is obvious once you start using it. The zipper apparatus is disappointing, from failing to have a baffle or wind guard anywhere in front of or behind the zipper itself. The zipper, while ykk brand, feels like the lowest level that they make , and has a laughably small, short and thin zipper pul. It immediately shed down feathers which is often to be expected but still not impressed by the amount or how quickly.the warmth was not what I was hoping for either, but that said, the total amount of full isn’t much despite being a highly rated 850 fuill. It is to note that this down is supposed to be hydrophobic to some degree, but haven’t heard the best from my friends that have tested that. The night I went out in question reached a low of 28 leaving me pretty chilly with pants, a baselayer and a long sleeve mid layer as well. For comparison, my 750 full microlight is hardly any heavier and would keep equally as warm, if not warmer, and has stood up to rain and thorns and fly fishing hooks for the past two years. my Rab doesn’t even have a hood, but I would still take it anyday over the arcteryx regardless of the price. I know after one winter season, this jacket would be toast even remaining under my shell. It just doesn’t feel like it’s made to let, and I I can’t have that anxiety when logging miles, bagging peaks, or doing whatever I need to do in the backcountry. If you have the money to replace your gear every season and you want to go with the lightest weight setup, this would be your jam, but for me, even at 250$ I can’t justify it

    Puffys don’t get much better

    I’ve been wanting this jacket ever since someone beat me to one at a famous outdoor company’s garage sale in Bend. I think it’s way overpriced, but the sale at Moosejaw, my customer cash there, and Activejunky’s cash back made it irresistible. When it first arrived, I loved the marine with contrasting piping color, but the jacket seemed a bit “flat”. Since then the down has lofted nicely. The jacket fits great, and I love the adjustability of the hood. I haven’t worn it in the cold yet, but I plan on skiing in it under my Beta AR jacket that I did manage to snare at another REI garage sale. To the complainers out there, I have lost a feather or two, but I’m not worried the the down will fly the coop.

    The best down jacket out there

    This jacket is amazing. It is light and packs into itself with ease, making it a no-brainer to bring into the backcountry in case the temps get cold. This jacket synches down around the waist, wrists and head if the wind is blowing or you can loosen them if you get a bit warm. The jacket is nice and slim and also works great as a layer underneath a waterproof shell.

    Arc'teryx as a brand doesn't make product to meet expectations, it makes product to exceed them. This jacket is as perfect example of minimalistic design, and a labor intensive construction process. The jacket is lightweight weighing between 10-11 oz depending on size, and has a great new improvement for the 2018-2019 season- the center back hem length is longer than previously. The fit is regular, but I personally recommend sizing up if you choose to layer, or like a more loose fit. I will always say that buying arc'teryx (although at a more competitive price), is better than buying multiple jackets over the years of any other brand. Buy one with a lifetime warranty that you can rely on.

    Love this

      But some time some fathers are coming out its should not do that it is so expensive company should make it batter

      Excellent item

        I love this sleeping bag it so nice but my place are did not get that cold so I returned

        I purchased this puffy for it's full features and light weight. I'm not terribly tough on clothes, but this one took a beating on it's first outing. After 4 days in the backcountry, there was a dime sized hole in the fabric on the left chest, and another on the right sleeve. Both required patching, (no company makes matching patches for the dark blue). My previous patagonia ultralight down jacket has been on many trips, and has yet to show a blemish. I like the warmth, the way the cuffs are stitched, and the feel of the fabric. But, it's the opposite of bomber.

        Worth it

        I got this for my husband when it was on sale and he loves it. He said sometimes Arcteryx items can be way too tight in the arm pit or chest, but this jacket fits him well. He wears it for all our backpacking and camping adventures. Works really well for him down to the 50's with a shirt underneath. After that he adds a few layers and is still comfy. He has a 40in chest and wanted to be able to layer underneath it. The large works well.

        All the good things people say about this piece are true. The one place I would caution interested buyers is its size.

        For reference, at 6 foot, 175 pounds with an athletic build and broader shoulders I wear a medium in the Beta SV, Atom, Squamish jacket, and Covert fleece, but went with a large here because I'd wanted the ability to comfortably throw it on top of other stuff during a stop in cold weather or at a summit, but also be able to use it as a stand alone piece and/or mid layer depending on conditions.

        The short of it is that at this sticker price I sized up to increase the versatility of the jacket. --If I'd gone with my standard medium it'd be too snug even for casual use. Putting it over my medium Pat' Nano Air the front of the Nano is visible by about an inch (tolerably comfortable if I were stopping for a bit during cold weather aerobic activity or something where the Nano were my main layer). Even on its own over a T it fits similarly to my medium Atom. I will also say that I own the Word On End Hoodie in a Large which I sized up for chill'n factor - the large hoodie is also longer and looser than the Large Cerium. This is mainly a sizing report because we all know how hard it is to get the fit right shopping online and paying the return shipping is a bummer so I hope it helps! My stoke level is very high on this exquisite gear and I can't wait to put it to use!

        Ultimate Warm and Light

        Packs down to nearly nothing, it's 10oz profile means you'll always throw it in your bag. The loft of this jacket is where it really shines, I can't imagine something being lighter than this while maintaining it's loft. If anything, throw a wind jacket / shell over top and you'll have a full winter jacket that packs to grapefruit size.

        Amazing warmth to weight ration

        I wore this jacket on several training hikes that were in the teens and twenties and also light snow. It held up with no issues and dried quickly from the snow once I hung it. I wore it all the way to camp 2 on Aconcagua without issue. The most amazing part of the jacket in my opinion is the hood. Super warm and hugs the face nicely which was especially useful on the high winds of Aconcagua. A few feathers have sprung out here and there and it initially concerned me greatly, but it doesn't seem to have affected performance in the slightest.

        Great Fit + Super Warm

        I've been a long time fan of the Atom LT and had little need for another insulated jacket until I move from Seattle to Utah. Winters are much colder here, so I decided to try out the Cerium LT. Turns out, it is a great jacket for when the temps dip into the single digits or lower. I'm really impressed by how light the Cerium LT is, and how well it blocks the wind. Great fit, nice color options. I can easily throw a shell over it. I would recommend this jacket to friends and family.

        Best down layer I own!!

          The quality of the product is amazing and the down stays properly inside the jacket the Lt is the model for me also not the lightest but the face fabric is exactly the right thickness so I don't rip it super easily.

          WARM, LIGHT and PACKABLE

          Love this jacket!!...was going to get a large after reading some reviews, but ended up talking to the Tech help and they recommended the X-Large,
          it is a perfect fit.
          Live in cold Wisconsin and just wear a shirt under and am warm.

          Light Warm Packable

            This is a must have piece. Lightweight, warm, packs into its own pocket. This is number 2 for me; replacing an older cerium lt.

            Amazing Jacket

              This jacket is amazing! It has a slim fit which makes it very stylish while also keeping you very warm.

              This mid layer is phenomenal! Extremely pack-able for hiking or climbing, and it is considerably more durable than I had originally thought it would be. I was pleasantly surprised as well when I discovered how warm it was in opposition to other puffy jackets I've had. Some of which were considerably larger and did not pack quite as well. 10/10 would wear along side Nicholas Cage in the opening scene of National Treasure.
