Customer Reviews Arc'teryx Thorium AR Hoodie

Just the best warmth for the weight, such a comfortable jacket that you would be forgiven for thinking it's going to be rubbish because it's so light but it is far from rubbish it's fantastic and I can't say enough good things about it. Just buy one and experience for yourself or you are simply missing out on the very best.

Love this down jacket. It's very warm and the material feels durable. Had worn it in Iceland under a hard shell. It looks nice by itself. Very happy with the purchase.

I spent a lot of time between this jacket and the Cerium. Ultimately, I decided I wanted a jacket for wearing around town and apres ski vs. a true insulated jacket for under a shell. This fit that bill perfectly. This has become my go-to jacket in the winter and replaced many bulkier, heavier, but not as warm or comfortable jackets.

I bought this jacket to wear under an old but still great Arc'teryx Theta AR shell specifically for a recent trip to a small barrier island just south of the Arctic Circle. There was still a lot of snow and ice and we spent much time outside either on foot or on a snow machine and its attached sled. Though it wasn't the forty below temperatures of mid-winter, it was still very cold. I am middle-aged, 5'10" and 160 pounds. When I tried on the Medium, it fit, but I wanted to be able to layer underneath it for a wide variety of temps. I bought the large and am so happy I did. It is silky soft, light yet warm, and so comfortable it's like wearing a cloud. I have long arms and the sleeve length is perfect. The back is nice and long and the drawstring around the bottom cinches in nicely so air doesn't invade. The hood is great and pulls up into a short tunnel that covers up to my nose. The zip pockets are comfortable and angled nicely. With my shell and typical layers underneath I was warm and cozy the entire time, even miles out on pack ice. I also wore my Thorium alone on warmer days and it worked great. The Nightshadow color is beautiful and compliments my shell nicely. I wholeheartedly recommend this amazing jacket.

The throrium AR was purchased by myself after the cerium lt and cerium SV. If I were able to redo my purchases, this would be the only jacket I would have purchased. Firstly, the outer fabric, while heavier than the cerium's, is far more durable for using it as a mid layer on cold days without precipitation. Hiking or skiing with a pack on shouldn't require a soft or hardshell jacket to protect a jacket's durability, which is the case for the other two jackets. The jacket's fabric, based on use, does a better job at keeping the down feather distribution in the baffles. After a year and a half of use, my cerium lt baffles appear deflated from use unless I spin them in my dryer, and my cerium sv gets cold spots in high areas of movement, such as the shoulders and elbows. The thorium also function better as a casual layer, easily layering over casual shirts and flannels, while still fitting nicely under shells. The outer fabric's construction has led to far less feather loss than the cerium's, especially the lt, which consistently has small white feathers poking through the stitching. Instead, most feathers, which are few, are larger and poke through the fabric in the middle of the baffle, which are much easier to massage back in without cursing and finger twisting. However, this jacket is without flaws. The hood is roomy and fits well, but the coreloft is less flexible and fits less well than the cerium's down hoods, which are also warmer. The stitching seems less durable, with many small threads coming undone. This is minimal in impact, but questionable. The jacket also might fit too large, but this is also practical for layering and creating extra warmth. The jacket is certainly warmer than the cerium lt, but obviously less practical in the autumn (although any aerobic activity with down is a lose-lose situation), but is more durable than the cerium sv. If arcteryx could make one new down jacket, it would use the thorium ar's outer fabric, but the fill weight and hood design of the cerium sv. This jacket would be so much better than either current edition.

This jacket is extremely warm. I've been using it as a stand-alone and it is very warm. I can only imagine how warm you would be using this as a layer.

I layered the Thorium AR hoody under my Theta AR and spent 10 hours ice fishing exposed to the elements in temperatures ranging from -22 F to 0 F and stayed comfortably warm. I had an Atom LT with me in case I needed to add another layer and I didn't need it. I was very impressed. I wear a large Atom LT and Theta AR. The large Thorium AR hoody is just slightly small in the torso and sleeve length for me. Not enough to make me return it for an XL. It does fit easily as a midlayer under my shell since I don't have a lot of excess bulk in the torso. The material seems durable enough but time will tell. So far I love this jacket.

I absolutely love this jacket. It's very warm and lightweight which was important for me as I am a train commuter in Chicago. It's so nice not to feel so bulky that you can barely move. I'm so glad I purchased this jacket!

Purchased this to wear under my Alpha SV and it keeps me warm. When you first try it on you question if something so thin can be so warm but retains heat very well. The revised zippers are great and stay up. Also worn as a standalone and delivers as advertised. Fits true to size.

Classic Arcteryx here. Looks great, smart features and engineering, very warm especially for it's size/weight, fits great, cut is ideal for thin to medium sized people. I'm 5'-10" and around 200lb, and a Large works great for me. Hood covers very well, and fits snugly, keeping cold air out. I couldn't be happier really.

Recently, I need a new insulated jacket for the winter. I considered three things before buying. The first is style. Second, it should be light and packable. lastly, wide use should be possible. There are various insulated jackets made by different brands in the market. But most of them made me look fat. I hate that, and that's why I chose acrteryx. At first, the products that I considered buying were atom ar hoody. It have the advantage of being very useful and easy to wash. But for me, packing size was a problem. My wife and I take our old puppy with us when we go hiking and trekking. Every time I have to carry food, water, and jackets(hardshells, softshells and insulators) for my wife and me because she carry a our puppy use her backpack. Weight and size are very important to me because I have to put things for two people in one backpack. So the next thing I considered was cerium sv hoody. It was enough to be worn outside and very warm. But I couldn't wear a my beta lt hybrid on it. Because it was too bulkier. That moment, Thorium ar hoody came into my eye. Frankly, Thorium ar hoody has not been on my list. Because I had an early version of Thorium ar and it was very disappointing to me. The problem with earlier versions is that it lose a lot of feathers. The old version had already lost a quarter of its feathers when it was shipped to me, and by the time of winter, half had disappeared. So I looked for a new model's review and Finally found out that the feather-loss problem was solved. Thorium ar hoody was exactly what I was looking for. When I first wore it, my wife told me it was like an tailor made. She was absolutely right. I am 180cm(5'11"), 89kg(196lbs) and has 44" chest, 33" waist athletic body shape. I bought a large size and it fits me like a my tailored made suit. It was a little bulky than cerium lt, but a little skinny than cerium sv. That means I can wear it on mid layer and at the same time under hardshell jacket. It may also replace mid layer. So it can be used like atom lt or cerium lt. Not long ago, I went to the mountain behind my house. The weather was -10C(14F) with strong winds. (So the body temperature was around -14C(6.8F)) My backyard Moutain was only 153m(500f), so I only wore Thorium ar hoody on the bass layer and it was warm enough. Thorium ar used 30 deniers material. It also makes me satisfied that it is more durable than ceriums(used 10 Deniers). The important point is that this new Thorium ar hoody does not lose its feathers. My new Thorium ar hoody traveled by airplane and truck from a store in New Jersey for a week and arrived at my home in Seoul, Korea. Nevertheless, surprisingly, not a single feather escaped. Also, to this day I have not found any feathers that have escaped. Acrteryx fixed the only downside of thorium ar, and I was very impressed with it.

I have an older model Cerium that I have been wearing for years. This year when I decided to replace my jacket I decided to go with the Thorium. It is not as packable or light as the Cerium but besides than that I am loving everything about it. The cut is longer than my old model Cerium by quite a bit and the same size (small) fits me better as it is slightly bigger. (regular fit vs trim and different models perhaps?) I am finding it warmer than the Cerium was and there is less down leakage so far. Something the Cerium seemed to do right from the start, probably because of the lighter fabric. It still has a lot of the features I loved from the Cerium which is so nice, that it doesn't feel like a downgrade. My one complaint is that the "hidden" side pockets make it so they are a bit harder to open and close as smoothly as the ones on the Cerium were.

I absolutely love this jacket! I live in Seattle, so it's typically pretty cold here. It's very windproof, which I love, and I've even been caught in a random torrential downpour and it kept me completely dry! The fit is very flattering and doesn't make you look puffy or large. I typically order a small or medium in jackets because I usually wear a thick sweatshirt underneath, and the small I ordered fits perfectly! The neckline is high and the hood stays on in the wind, keeping you very warm. Overall extremely satisfied with this jacket and the price!! Would definitely recommend to anyone searching for a good Fall/Winter down jacket.

I think Arcteryx is the best product on a market and can easily bit Canada Goose. I have couple of different models of the jacket and very happy with the purchase. It's funny but jacket can keep you warm on colder weather condition, like -10, better than on +1.

I really like this jacket. Keeps me warm is light weight. Just a perfect jacket

Love Arcteryx, you get what you pay for. This jacket is warm, good looking and excellent for everyday wear

I love every product I own. This coat is light weight but warm and cozy. It's comfortable to wear while running my errands and walking the dogs. It's the first coat I grab now as I run out th door.

Exactly what I wanted; seems to keep me comfortable over a very wide range of temperatures. Good hand pockets, but I wish it had a pocket for sunglasses.

This jacket is great for cold weather day to day use. I go in and out of buildings at work and this jacket allows me to stay warm. I brought it to an alpine lake where it was sub 32F, kept me warm after a long hike to standing still. Also my favorite to wear when rigging up rods at the truck and putting waders on until the weather heats up. The cut is awesome, very clean but doesn't constrict movement.

Perfect in every sense. Light as a feather, but warm as toast. Seriously waterproof too. Highly recommended.
