    Exceptional warmth-to-weight.

    As the lightest down jacket in the Arc'teryx Essentials collection, the Men's Cerium SL Down Jacket offers incredible warmth packed within an extremely lightweight and compressible jacket. Ideal for chilly backcountry adventures, this down jacket features Down Composite Mapping with strategically placed 850-fill European grey goose down for maximum warmth, and Coreloft 40 and 100 synthetic insulation an ideal blend of warmth and moisture management. The ultra-light Thisela (nylon) face fabric won't weight you down on minimalist backcountry missions, and its DWR finish sheds light snow showers when you're skiing down your favorite face. In addition, the jacket's elastic rear hem seals out cold drafts, and the zippered hand pockets include a stuff sack for easy stashing.

    Surprisingly warm for how light it is

    • Familiarity: I've used it several times
    • Fit: Runs small
    • Size Bought: X-Large
    • Height: 6'0"
    • Weight: 200lbs

    This is my second Arcteryx Cerium jacket. The first I purchased was a size large and was a little too snug. My son happily took that one so I purchased another, size XL. I used my previous jacket quite a bit during the winter. The jacket is extremely light but definitely keeps you warm. I was a little skeptical the first time I went to Flagstaff, AZ in January and it was zero degrees. Despite how could it was, the jacket kept me very warm.

    Doesn't get any better

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: Large
    • Height: 6'2"
    • Weight: 180lbs

    Warm but not hot, perfect fit for athletic figure, light like feather, folded into the sack of 2-fist size - ideal for travel. Not a surprise for the quality and tailoring - it is Arcteryx. Promised 2 day delivery but arrived within one day! Can't be happier.

    High quality, light and warm.

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Medium
    • Height: 5'10"
    • Weight: 175lbs

    I was looking for versatile down item to use for layering for various activities, like hiking, backcountry camping, skiing and just casual wear around town, and when travel.
    This is high priced piece, though is definitely worth the expense. Attention to details, and highest quality of material is obvious.
    Only negative is that bird logo is not stitched one.
    I may add more information after first couple skiing and camping trips.

    Go-To puff coat

    • Familiarity: I've put it through the wringer
    • Fit: Runs small
    • Size Bought: Large
    • Height: 6'0"
    • Weight: 185lbs

    Bulletproof and is hands down the best down puffy I own. Super light and has stuff sac for compressing into my pack and staying organized. Only gripe is I should have bought the hooded version. Runs a tough small but Super Sweet item!

    Arc'teryx Cerium SL Down Jacket

    • Familiarity: I've used it once or twice and have initial impressions

    Pros: Ultralight weight, stuff sack included, packs down very small.
    Cons: Fit. For me, Medium was too snug, Large is big in the shoulders. I seem to fall right in-between sizes with Arcteryx. For reference, In the Arcteryx Atom LT I am a Large and in the Patagonia Ultralight Down Jacket I am a Medium.
    Side note: Wish they used Hydrophobic down.

    All around awesome

    • Familiarity: I've used it several times
    • Size Bought: xl
    • Height: 6'3"
    • Weight: 190lbs

    This jacket is very warm for it's almost nonexistent weight. The fit is somewhat unique. I am 6'3" and 190lbs. the XL is a great contoured slim fit. Hugs the body nicely but still room to layer and move. Very odd though I have the Cerium LT as well and ordered a XL as well. definitely a boxier cut in the torso. I go to the gym A LOT so the XL fits my shoulders and chest but I have a 32" waist so a V shape for sure. I am not sure why the two practically identical jackets are cut different but for those of you on the fence I thought I would share. I ordered the Azul and it's a great color in the sunlight. I feel the build quality is top notch and I have taken a walk at 29* and been just fine with a cotton T shirt on underneath. I'd say if I had to stand around a heavier jacket would be better. Hope this helps.

    Pound for pound the best

    • Familiarity: I've put it through the wringer
    • Fit: Runs small
    • Size Bought: XL
    • Height: 6'0"
    • Weight: 195lbs

    My "go-to" jacket for technical and casual wear. As with most clothing Arc-Teryx makes, their sizing seems to be for the more slim built frames. Therefore, being 6' 195lb, I simply increase what would normally be a Large in most other outdoor clothing lines and order the XL in Arc-teryx.

    Buy it!!!!!

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Large
    • Height: 6'2"
    • Weight: 195lbs

    I've been on a search for the perfect lightweight coat for months. I've ordered the lightweight coats from TNF, Marmot, Mammut, and Mountain Hardware. Either the fit wasn't good, they were too puffy, zipper on the wrong side, etc. This one is perfect. It's the lightest coat I've ever owned and I have a bunch them. It's not only light but almost winter coat warm. I have a puffy TNF coat and it's as warm but 1/10th the weight. What a great value and the fit is perfect. I'm 6'2" 195 and its athletic fit, good sleeve length, good waist length, and just the right snugness. I bought a Large. You won't be disappointed.

    Really nice but a little tight

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: Runs small
    • Size Bought: Xl
    • Height: 5'11"
    • Weight: 235lbs

    I love Arteryx jackets. They usually fit me pretty well. Reading some comments on this one and can echo those that say it's top quality, compressible, extremely warm for being so light, but tighter around the waste and chest than most Arteryx jackets.

    Being a mid layer it's better being a little tight so I'm not sure if I'll keep it or get a bigger size? It all depends if I use it for what it was designed for our decide I simply want something casual. It looks and feels really nice.

    Scrawny malnourished supermodel sizing.

    • Fit: Runs small

    WTF are the people at Arc'teryx thinking with their sizing?

    Don't get me wrong.. I love the jacket but the sizing is just too weird.

    I have many different Arc'teryx products from pants to jackets to packs to gloves. I have never had issues with their sizing before this jacket. I am usually between a medium and a large for jackets and tops from them. This one is tight as hell in a large through the chest.

    What is it with the new metrosexual cuts and sizing coming out? I am not tall at all and this large is fine through the arms and torso on me.

    I have to warn anyone that the sizing is just weird as hell with this jacket. The jacket is a great piece and I would prefer it to any other thin down puffy out there. The sizing just isn't going to cut it.

    I will give it 3 stars though if the cut was normally sized I would give it 5.

    So, how small does this run, really? I wear a small in every other Arcteryx jacket I've ever owned or tried on. 38" chest, 5'9", 145-150lbs depending on the season. Do I get a small or a medium? Probably be using as both a mid layer and wearing it around town on its own.

    What is the actual weight of this jacket (medium) ?
