I own 4 Cerium jackets from past years.Every one of them had a stitched logo at the chest. Loved it. It set the jacket apart.Now there is no more logo at the chest. They moved it to the sleeve cuff. WHY??I like my chest logo, especially when I pay 450$ for my jacket.Sizing is the same as before. I'm 5 foot 2, 110lbs, straight up and down and flat chested. I took S.

I love this jacket. If most button down shirts are too tight in the shoulders, youâll also love this jacket. The sleeves are longer than most jackets which is a plus in my opinion. I do believe it is true to size. Iâm 5â6â between 140-150 lbs, athletic build and ordered a medium. The waist length fits just below my hip bones. I think itâs the perfect fit for a puffy jacket being fitted, but not too tight. I havenât worn this yet for winter activities, but itâs great to throw on quickly to walk the dog or stay warm. If you have a larger chest (bigger C or D cup), this jacket would be tight to zip up and I would suggest sizing up.

I wore this jacket almost every day this winter, itâs super cozy and perfect for a Canadian winter! Great for snowshoeing through the woods, watching wildlife or heading into town for some errands.Wearing this jacket during field work under the Beta AR kept me warm down to -25C. It can be too warm while doing high output winter activities, however itâs super light which makes it a great addition to my pack as an insulating layer after activities.My favorite thing about this jacket is the hood! Nice and warm as well as a good fit that doesnât blow off in windy weather.

Iâve had this jacket for 2 years. Keeps you warm and was nice for traveling. I agree that it definitely runs small! However, I wouldnât recommend. I had the outer fabric split out of nowhere and the full was coming out. I reached out to Customer Support and was told that ânormal wear and tearâ isnât covered under the Limited Warranty. But this was not normal âwear and tearâ. The best customer service would offer is a clear patch that looks like packing tape that I have to apply myself, or 40% off of a replacement. For the cost of this coat, I would expect better. Nice coat, but really be carefulâŠ
So far this jacket has not disappointed, even though I just started wearing it. It runs a bit small. I am usually a women's medium and there's a tiny bit of room. The M fits well with just enough room for a couple decent base layers. But that means it also fits well under my size M shells. The arms are long enough, which is usually a huge issue with midlayer down jackets. This is especially nice since I am using it for bike commuting in the winter. It was -15C this morning while I was cycling and under my shell, I did not feel any cold leaking through in any spots. The hood is nice and roomy - supposed to be helmet compatible, which I think might be generous, though I haven't tried yet. However, it fits over my ponytail/bun very nicely, so I can't complain.It's ... MoreSo far this jacket has not disappointed, even though I just started wearing it. It runs a bit small.

But so far I'm pretty impressed!
I've had this jacket for 4 years, and it's become my most reached-for layer. I bring it on every trip because it's so lightweight and packable. Takes up less space than my toiletries bag. It's the perfect layer for in between your wool sweater and your shell.That said, here are my two "but"s. One, it's actually not that warm. It's great for taking the chill off or adding another 10Âș of warmth to your layering system. This is definitely not a standalone jacket though. I can count on one hand the number of times I had this jacket on without another layer above or below.Two, the outer material is really delicate. Twice now, I've had it on as a belay layer, and then forgotten to take it off before heading up the next pitch. I'm not talking about chimneys and ... MoreI've had this jacket for 4 years, and it's become my most reached-for layer. I bring it on every trip because it's so lightweight and packable.

Twice now, I've had it on as a belay layer, and then forgotten to take it off before heading up the next pitch. I'm not talking about chimneys and off-widths. I'm talking warming up on a 5.7 to 5.9 vertical wall. The first time, I used superglue to seal up the little puncture holes. This second time, I've got about 4 new holes, and they're more like gashes than puncture holes, so unfortunately I think I'm looking at a replacement jacket this time. (Sadly, Arc'teryx is out of my budget at this point of my life, so I'm gonna have to switch brands.)I'd still recommend this jacket, but with a strong disclaimer to remember to take it off âor to protect it with an outer layerâ if you intend to do anything active in close proximity to rock or ice.
Love the jacket, but the fit is not quite right. My measurements are spot on to the size chart, but the shoulder and chest is pretty snug with just a base layer. Would be fine if I only planned to use this for travel in car, but would be restrictive for activities. I'm returning for the next size up in hopes that it has more room in the chest but not too much in the hips. Otherwise I loved it, super warm and good length. Minor issue with return option not showing in account for full price / this season jacket, but this was quickly addressed by the customer service team.
This jacket is incredibly light and compact. The fit was a little bit tight, so I think I would choose to go up a size from normal. The zippers feel a little bit flimsy and cheap. This jacket kept me incredibly warm while I was hiking in November in Minnesota. The hood kept out the wind very well. Overall, I really like this jacket.
I purchased this for a backcountry skiing layer and bikepacking due to it's packability-to-warmth ratio after some research and trying a few puffies on for the right fit. Fit: slim, but plenty of room for arm articulation (covers wrists when bent over on the bike), length is not too long - right at hips. Some other puffies swallowed my body frame due to their length, this jacket is short-torso friendly. I have a fairly straight figure, so I had to cinch the hem drawstring. I'm 165cm/5'5" tall, 52kg/115lbs, bust 85cm/33.5", waist 64.8cm/25.5", and hips 80cm/31" (where the jacket hits). Performance: packability into the included stuff-sack is GREAT, very easy to take along as an emergency layer. Saw some very light rain in Moab, stayed warm and dry. I am disappointed ... MoreI purchased this for a backcountry skiing layer and bikepacking due to it's packability-to-warmth ratio after some research and trying a few puffies on for the right fit.

Performance: packability into the included stuff-sack is GREAT, very easy to take along as an emergency layer. Saw some very light rain in Moab, stayed warm and dry. I am disappointed with the durability, since I already see feathers leaking out at the seams after just a couple months of use; however, this doesn't seem to be an issue... yet. Material is thin, but expected due to packability. Appreciate the three-pocket design.
I have this jacket in the lovely when clean Dew Drop color, which is very light, thus necessitating frequent washing otherwise even with infrequent use the cuffs and collar become dirty rather quickly. Therein lies the issue. I have followed all of the washing instructions to a T. I have washed this jacket with other down jackets manufactured by other pricey and reputable outdoor brands and this one is a disaster. After three cycles in the dryer with two tennis balls and two wool dryer balls all of the down clumps to the backside of the arms - my other brand jackets came out fluffy as ever with no clumping/migration issues with the down. This has happened every time I have washed the jacket (even by itself), so I can only conclude that it must be a defect with the ... MoreI have this jacket in the lovely when clean Dew Drop color, which is very light, thus necessitating frequent washing otherwise even with infrequent use the cuffs and collar become dirty rather quickly.

This has happened every time I have washed the jacket (even by itself), so I can only conclude that it must be a defect with the jacket, not my washing procedure. I have many, many other Arc'teryx pieces that have been wonderful (the Patera Parka is one of the best in my closet and I wear it daily in the winter), but this jacket just does not live up to the advertised quality and "innovative" design of the Arc'teryx brand. Based on other reviews I've read regarding the issues with the down, how long the warranty process takes (2+ months), and the likelihood that the company will determine this isn't covered by warranty as it has done with so many other purchasers of this jacket, I am probably stuck with a very expensive purchase that cannot be washed (this is usually very dirty looking) or else it won't be insulating and will likely stay in the closet.
