This jacket as been following my adventure for more than 5 years now. It is very great for skiing. The snow never comes inside because of its length. I love the under pit arms and hoods fits very well with an helmet on! I have been wearing it at the resort as much as in the backcountry and both activity have been great for this jacket.Cons: Since it is very ski specific, I find it a bit bulky to bring ice climbing or in my hiking trip in the summer. It is not ideal to wear it with a harness, it is kind of difficult to adjust everything (gear, harness, jacket, bibs etc.) so it fits nice and confortable. For hiking trip, it is a very long jacket so your butt is cover but you have carry this extra length of jacket.Size : Medium would fit better my body but the ... MoreThis jacket as been following my adventure for more than 5 years now.

swapped the Beta AR for Sentinel Jacket and I'm super happy about it. The jacket stands out for its functionalityand comfort. It's definitely an investment for a serious outdoor enthusiast seeking seeking a jacket for versatile outdoor activities. While the size runs small, and the price is quite steep, it’s comfort and durability during all weather conditions are totally worth it.The fit of the Sentinel Jacket is much smaller than my previous jackets. Being 160 cm tall and weighing around 60kg I usually wear S-M, but this time I went for XS and it was the right choice. I can even fit a cerium jacket underneath it and still feel comfortable.The hood and the skirt are excellent for skiing and ski touring as they connect to my sentinel pants.The only drawback ... Moreswapped the Beta AR for Sentinel Jacket and I'm super happy about it.

Great purchase. Fits perfectly. Great quality.I was considering buying size large because it’s a shell jacket so need to allow space to wear layers and potentially insulated jacket bit went for Medium and so glad I did. I usually wear Medium and it’s big enough to wear many layers underneath and goes on the top of insulated snow pants perfectly. I read some reviews that it’s tight on a hip but for me it is perfect. I’m 5.10” and 150 pounds with pear shard body so pretty big bum (42 inches to be precise) and the jacket is pretty loose on my bottom. If you’re short, sleeves might be too long for you although for me sleves were perfect also.

This jacket is perfect for skiing and adventures! I love it!I am 5’7, slim build, and I usually wear S for Arc’teryx, but for this jacket I found it excessively roomy even for layering. XS was perfect though, not too baggy but with comfortable space to layer up.The zippers are a little annoying.. the zippers on the Nita jacket is way smoother but this jacket was better over all.
I recently purchased the Sentinel jacket, and I must say, it's been a game-changer for me. The straight fit and longer length, reminiscent of snowboard style, not only looks fantastic but also provides extra coverage, making it perfect for those chilly days on the slopes. I bought the boxcar/pytheas colorway it's unique and stylish!One of the standout features of this jacket is its soft lining, which adds an extra layer of comfort, wearing it for a full day on the mountain, it feels cozy and warm. The hood is another winner – it easily fits over my helmet without impeding my vision or movement, which is crucial when I'm on the slopes.Speaking of warmth, this jacket truly shines on those bitter cold days.

During the -30 degree January chill, it kept me incredibly warm and protected from the elements. It's rare to find a jacket that not only looks great but also performs exceptionally well in extreme conditions. Needless to say, I absolutely love it! If you're in the market for a reliable, stylish, and high-performing jacket, look no further than this one.
I have been snowboarding head-to-toe in Arc'teryx for a couple of decades. I love the brand, the layering system, the durability. I have been wanting to buy this shell, but the colour options are terrible. I snowboard 60-100 days per year in Colorado, including in the backcountry, bowls, trees. It is very important to be visible on the mountain for safety reasons, so dark colours like the black and forest green offered here don't work. Additionally, the only bright colour option for women shouldn't be pink - we don't always want to be wearing pink. The pink design here also doesn't work well because the back has a white patch which is likely to get dirty when sitting on a chairlift. Does Arc'teryx do focus groups to inform designs? If so, I would volunteer.
I’ve been wearing Sentinel jackets for over 5 years for mainly backcountry splitboarding, but will also grab this for inbounds riding with some extra layers. The cut and length and comfortable; no fiddling. It fits just right. The fabric is soft even though it’s technical. I’ve never been able to rip the fabric, even when riding through trees or getting it too close to sharps. I’m usually a M or L in Arc’Teryx jackets and size up to a L in this because I have wider hips and like a little baggier look.
This is a nice jacket, well put together and seems comfortable when I tried it on. I have no doubt it would keep out wet snow. But I ended up returning it for a couple of reasons. The biggest one is that there is no external chest pocket. That's where I like to keep my phone and it was a deal-breaker for me. Not sure why this jacket doesn't have that when the Rush has two of them. The second reason was the colors. Liberate is the only color bright enough to be seen in the woods (I want to be visible) and for some reason they put a white section right where the coat will contact a dirty chairlift. Tools not jewels, but I don't want to be skiing for the next several years with a brown butt and lower back.
I really want to love this jacket. It’s clearly good quality and I love the colour options. Which is rare for women’s outdoor gear. I want to be an arcteryx girlie this winter, but sadly it is just not the fit for me. I am 5’2, petit and curvy and it was boxy in the shoulders and tight on the booty. It’s very frustrating that this body type is not represented in the outdoors and majority of gear for my body type is extremely hard to find. I hope one day arc makes a line of clothing that can help out us curvy shorties. We like to ski too. We like to the outdoors too!
First and foremost, this winter has been very warm and wet, and I have not used it in anything under 20 degrees. That being said, this jacket was phenomenal when it has been wet. This thing has kept me so dry, it’s pretty amazing, and I’ve gone snowboarding in some pretty warm and wet weather this year. The jacket fits really well also, it isn’t too tight so you have room to move around, which is helpful while snowboarding, but it also isn’t crazy baggy. There is a bunch of pockets, which really come in handy, and they don’t leak and keep your stuff dry. The color is very out there, but I’ve come to love it. This jacket is seriously awesome. It’s a phenomenal ski jacket.
