The Sentinel Insulated Jacket storms onto the mountain with a new revised look for the new snow season. Arc'teryx has built a jacket that has evolved to perform as the ultimate winter sport touring and freeriding jacket. With a waterproof and strong 2-layer GORE-TEX fabric that expels and stops intruding water in its tracks plus synthetic Coreloft? insulation that provides durable warmth, making sure you will be able to stay comfortable and focus only on the mountain no matter the weather. *Jacket is blue, yellow images used only for demonstrative purposes.

I bought the Sentinel jacket because I am outside a lit in all kinds of weather. I wanted a coat that was warm, waterproof, windproof and one that I could layer underneath if I wanted too. The length is great too because it covers my rear end so I can literally sit on a wet bench in the rain and still be dry. The interior skirt will keep out drafts too and if you partake in winter sports, it will keep out snow when snapped. It’s a greT insulated jacket! For reference, I am 5 feet, 2 inches tall and weigh 115 pounds and the size small fits true to size.

I love this jacket! It's very cozy, has all the pockets I need in all the right places, lets me move in every direction without restriction (although being able to unzip from the bottom is really useful at times!), it's waterproof, and the fabric doesn't crackle. I also love the length, which totally covers my hips and bottom. I have it in Boxcar, which is a lovely color. I'm 5'2", 108 lb, wear this jacket in size Small, and it works beautifully for me. Totally recommend!

I ended up exchanging this for a size larger directly through Arcteryx since MJ was all sold out of the color I wanted (Quantum). I love the jacket! high quality, as expected. My one gripe is how tight the top half fits. I am objectively slim, I'm not super muscular, and I'm about as flat-chested as they come - even on me, the shoulders and chest were tight!! I have other Arcteryx jackets in a small and those all fit fine, with room to spare. I had to switch this out for the M, which then made the sleeves a little longer than desired but....overall a fine jacket. The small might have been okay but for such an expensive coat, you want it to fit right.

This is the perfect coat for both backcountry and resort skiing. It's easy to layer under the coat depending on your activity and pit zips are key for cooling off during a warm tour. I read reviews that the sleeves were too long, and they are long, but the length didn't bother me. Better to be a bit longer so you have overlap with your mittens. I love the length in the torso and that the zipper comes up to just above my chin. The enigma color is super super dark green- almost looks black until you see it in natural light. Really cool color. Arcteryx is expensive, but for good reason. Great quality coat- like Maggie Rogers says, I'm gonna love it for a long time.
I like the brand Arc’teryx and have a few items. I am 5’6” and 140lbs. I bought the Sentinel LT because the regular Sentinel is too short) I needed this ski jacket to provide warmth and protection during bad weather. I like the hood that totally covers your face and head except for the goggles. It fits well ( although on the large side of you don’t layer)and allows room for a down jacket under it. I like the pockets on the arm and sides and inside. The jacket was way too long reaching the bottom of my behind. The ski skirt also was not comfortable and kept on riding up. This jacket would have been way too long to ski with so I had to return it.I just ordered another Gore-Tex Arc’teryx jacket ( The Beta SV for Severe Weather...I like to be completely covered). ... MoreI like the brand Arc’teryx and have a few items.

I was told that I wouldn’t need to buy DWR spray in order to maintain the coat, but after just one wear the water soaked through the first layer, making it drenched, dripping, and heavy. I wouldn’t have bought it if they hadn’t lied about the outer layer not requiring spray to stay waterproof. I tried to return it well within the 30 day window with my receipt and the original tags, but they argued with me and refused to take it just because I had worn it once. My family won’t buy from Arc’teryx again.
I am fairly tall (6') and bought a L and XL to see which fit best. Somehow the L was too small and the XL was too big. Sleeves are puzzlingly short in the L. There is a lot of bulk in the midsection of the jacket for both sizes, and the length on both were crazy long (even with my long torso). I returned them and am going to try again with the Beta Insulated.
What is there to say really? Arc'teryx makes the best technical shells and the Sentinel AR is no exception to this rule of thumb.The Incendia was the other shell under strong consideration, but the Sentinel ended up being on sale "biglier" - and this ended up being the final arbiter of decision making.. But if you're looking for a beefier face fabric (and seductive charcoal color), it's definitely worth thinking about as an alternative.It's probably worth noting to not get an insulated version (the IS), you want to layer instead. So the AR or LT..
I’m 5’6” 122lbs, C cup chest. Didn’t love the fit of this jacket in my normal size of small. It lacks pockets and the snow skirt is too snug, even for me (I have small hips/bum, slim/athletic build). I do prefer a super roomy fit when boarding (resort). I hate ANY sort of restriction when I ride. Given that, I didn’t try to size up, which may have been great. Decided to go the shell only route and order both S and M of the relaxed sentinel shell. Stay tuned for that review!
Overall, I really liked this jacket and wanted to keep it. It's a pretty loose/baggy fit, which I liked. Obviously, that will depend on what size you get. But overall it has what I would describe as a relaxed cut, which I liked. It's also quite long. I am fairly tall (5'8") and I would say it was *almost* too long, but I liked the added coverage. In terms of warmth, I would say it was only kind of warm. Warmer than a shell, obviously, but if you run cold and/or are looking for protection from really cold temps and wind when skiing, this might not cut it without a pretty warm mid layer underneath. If you run warm or are skiing on warmish / sunny days, it would probably be great. Anyhow, at the end of the day I returned it because it lacks an external chest pocket.

I just can't understand a jacket at this price point not having this feature in this day and age. Maybe there's a reason for it I am not aware of? But I need/want quick access to my phone and an external chest pocket is really the only way to do that, in my opinion. If an external chest pocket were to be added some day, I would for sure consider re-purchasing this jacket for mild weather ski days.
