Rated 5 out of 5 by from Bought this for the fit! I bought this jacket for the fit as I have a competitors thermoball product which didn't fit quite right. I purchased this jacket after reading that the sleeves are a little longer and the down insulation a little warmer. Well, the fit on this jacket was just perfect. The down insulation proved to be a bit warm for downhill skiing, but with layers you can regulate that. It was a bit too warm for spring skiing, but I love it none the less. When I first saw Arcteryx products, I thought they were just marketing a brand, however, these products have proven to be above and beyond a price point market. These products are comfortable and perform as advertised.

Rated 4 out of 5 by from Would be perfect, except for one critical flaw I love my Cerium LT. I have the nighthawk color. I'm 5'-8" 150lbs and the small fits just right. it's super warm, lightweight, totally stylin'. i like the collar, long and snug enough to be functional, but not super-high like the Mammut and Mountain Hardwear equivalents. My only beef with it is this: no waist cinch. The waist hem is just a bit loose and has no elastic or cinch to tighten it up on those drafty days. i can't imagine why this wasn't included in the design, as it's an almost weightless and costless feature. it's absence is the only thing keeping the Cerium LT from being a 5-star piece.

Rated 1 out of 5 by from Great style, bad quality fabric The jacket is warm and has a great style as other reviews have noted. However, my jacket has received multiple small tears even with light use. I am always very careful with my belongings and have only used this jacket for light travel and my daily commute. My jacket now has 3 significant tears in it. Overall I am highly disappointed in the quality of the product coming from a brand with a great reputation and a product with a high price. I love this jacket in all other ways but am extremely disappointed in the quality. I only recommend this jacket if you are not going to wear it much or don't care about rips that cause the insulation to leak out. I was ready to love this jacket when I bought it but am now left disappointed.

Rated 5 out of 5 by from Excellent Mid Layer Jacket I bought this jacket to pair with my Parsec hard shell jacket and I must say that I absolutely love this piece. Even as a stand alone jacket the Cerium LT is great, fits your body much nicer than other competitors jackets that i have tried on. A major selling point and something that i found very cool is that the jacket is able to fold into itself and be tucked away into a inner pouch found in the left pocket

Rated 5 out of 5 by from Very Light and Very Warm I generally take a medium in Arcteryx clothing, as I am very slim at 6' and 140lbs, but with quite long arms. The medium Cerium LT fits me perfectly. I have used it as an outer jacket in the urban environment, and as a mid layer while skiing below -10C, and at all times it has kept me warm. The only very minor point is that in 3 months of use, two very small feathers have come through the outer layer. Hopefully this is just a bedding in issue, but at least it proves that the down is real.

Rated 5 out of 5 by from Excellent multifunctional piece I've used my jacket for 3 seasons over my past year of ownership and it's held up well - I'd even claim it remains in pristine condition. What makes it work for me is it's portability (packs small and weighs a pittance) and it's versality in terms of the various ways I can use it in a meaningful fashion in the backcountry. It fits under my Beta LT hardshell although not many scenarios find me deploying it in such configuration. I often use it under my Squamish (ie windshirt) when taking a rest after a high output hike/climb. When it's really cold, I'll layer it under my Thorium AR or under a synthetic 'puffy' (in my case Rab's Xenon or Generator). It's been used quite often as insulative backup in my sleeping bag and quilt. If I'm moving and it's above ca. -5 C then I find the jacket too warm to wear. Even idly walking around town in the temperature span of 0 - 5 C, I find I start to sweat, and then I'm just wearing a base layer beneath (though I always have a windshirt above it--I never wear the jacket as my outermost piece) To summarize the activities/scenarios where I find this piece to excel in usefulness , I'd say it's for quick deployment (from an unobtrusive presence in my pack) when stationary. In really really cold weather (colder than - 10 C), it's an excellent complemenatary layer to add beneath another puffy, be it down or synthetic. It slips easily under such jacket and offers a remarkable surge in experienced warmth. It's also nice to put on when waking up in a tent on chilly mornings. The zippers are dainty but haven't failed or caused any issues during my year of use. An occasional escaping feather (I doubt true down was ever a culprit) has been spotted piercing it's way to freedom but it's never caused concern of a massive exodus. The jacket's down has a claimed fill power of 850 (US) which tracks rather well with my experience of various down products; I have several products with 850 fill power, though the down's fill power in these pieces is measured in accordance to EU standards. The 850 EU (with Pertex Quantum shells) are definitely 'puffier' than the Cerium LT. Only true down, as opposed to fine plumey feathers, occasionaly sneak out of those pieces. The few feathers/plumes that began migrating from my Cerium LT always had fine and sharp quivers that led the break out. I chose the Cerium LT specifically without a hood since it was intended to almost always be worn under other piece when outdoors, and all these pieces had their own hoods. I also didn't want a hood hanging off the back of my head, gathering rain or snow on occasions a down hood over my head entailed insulative overkill. In summary, it's a sweet and multifunctional piece of gear that tags along in cold climes, offering high thermal insurance per its weight and packability. It's turned out to be a very good purchase. The tailoring/cut is, per many of Arc'teryx's trim fitting pieces, impeccable--it looks almost too good while also tracking comfortably with range-of-motion needs.

Rated 5 out of 5 by from Great fit and construction I was hesitant about writing a review without being able to properly evaluate the jacket, but I felt I could offers some insight into the fit and construction. First of all, I am 5'10" and 160lbs, and I wear a medium in just about everything I own from any brand. This jacket is no exception and fit exactly like I would expect it to. I prefer more of a tailored fit, and I don't like a lot of extra room and bulk. The Cerium LT accomplishes that. In fact, it fits exactly like my Atom LT does which is also a medium. I do not feel there is an over-abundance of room in any one given area. This is one of the primary reasons why I bought this jacket. I have a TNF Nuptse that has too much room in the mid-section, and is a little too michelin man for my tastes. This jacket offers a much sleeker look without being overly bulky. In fact, it fits really well under my Stingray shell which is also a medium. The length is pretty similar to the Atom LT. It's slightly longer in the back, and hangs just below the waist line. The bottom of the jacket does not slide above my paints when I reach over my head. I really love the cuffs on the Atom jacket. It is one of my favorite style cuffs, and at first I wished that this jacket would have the same cuffs. I was pleasantly surprised by the cuffs though. In person the construction is nicer than what it appears like in the pictures. The pictures make it look like it's the typical thin elastic band that you see on a lot of jackets. They constructed the band so that it lays flat against the skin though which is a nice touch. I can't really comment on the warmth, since it is still too warm here to give a good evaluation in that regard. All I can say is that it feels at least as warm as my Nuptse jacket. So far I have no concerns.

Rated 4 out of 5 by from WARM, but not slim. Very warm, very light and very compact, BUT I was excited most about the CUT of the jacket and that was a let down. Was keen for the slim cut, but the XL is very baggy and does not fit as hoped. I am 6'4" and 185 lbs with an athletic build and need the XL for shoulders and arm length, but there is a good 5-6 inches of extra material around the mid section. Not sure who the per portions would fit? Going to re order a Large, but pretty sure the sleeve length will be to short. May keep the XL, but will have to have it altered to make it usable as a mid layer.

Does it have a hood as the description says? I don't see one.
