The Thorium Hoody is solid option for someone looking for a jacket that is warmer than the Cerium or Atom line as a stand alone option. It can be used on the coldest of days under a ski shell without feeling cumbersome or too bulky. The fit for me (5’10 170lbs) in a medium is trimmer than other “regular” fits. Not tight but the bulk of the down does create a more form fitting feel in the chest and arms. Although the description states it is helmet compatible, it will not work over a large size Smith ski helmet. No way to comfortably put the hood over the helmet and have the jacket fit normally - can’t zip it up/allow the jacket to lay on the shoulders. Maybe a lower volume climbing helmet would work but I imagine it would be really tight.

I needed a jacket without worrying about the wind or cold air piercing through the jacket. For years I’ve been trying to find a down jacket for the quality and warmth for a decent price from a respectable brand. Boy am I happy I purchased this for our Vancouver weather! It’s warm, I have room to put on a sweater, the hood is also very warm, and it’s packable for my winter travels! I’m 5ft so the length is perfect for me. I usually have to size up for jackets just so I can wear a sweater but it’s safe to say that this jacket doesn’t require me to wear a sweater which is exactly what I’ve been looking for. So far the temperature has been 4 degrees in the city so I’m excited to test it out during the snowy days.I’m hoping that sometime in the future the logos will be ... MoreI needed a jacket without worrying about the wind or cold air piercing through the jacket.

It would be helpful when your out for walks at night time especially when it gets dark early around 4pm during the winter (and it’s still dark when your on your way to work in the morning) and you have to cross the cross walks without good street lights. Just a thought!

I bought this version because its longer than the thorium, I’m 5’2, 120lbs, athletic build with wide shoulers and I wear a small to layer. An XS fits as well but a bit tight around my shoulders. Bought this a month ago in Toronto during black Friday and I would not buy this at full price. It’s not as warm as you think unless you’re moving around a lot, so I recommend layering. I commute and wear thermal layers and I still feel cold at only -2C. If it’s windy out, you’ll also feel cold, but I have hope that this jacket will be appropriate for winter sports when I head to Blue Mountain in January. The collar of the jacket goes up really high and is quite stiff, so it pokes in your face unless you zip it down your neckline or all the way up. Zipping up the jacket is ... MoreI bought this version because its longer than the thorium, I’m 5’2, 120lbs, athletic build with wide shoulers and I wear a small to layer.

The collar of the jacket goes up really high and is quite stiff, so it pokes in your face unless you zip it down your neckline or all the way up. Zipping up the jacket is also VERY finicky, it’s angled weird and doesn’t go through the bottom zipper easily— I can’t imagine zipping up when you’re wearing gloves or have cold hands. The interior breast pocket is a bit too shallow for my liking, but nothing has fallen out yet so its good enough. The hoody when zipper up fully is also very puffy and I like it, but it might look weird if you’re not into that.

I’ve had this jacket for a couple weeks now, but it has been put to the test in our cold, dry snowy climate. The length is simply perfect for me- at 5’4” and 125lbs, the small just covers my heiny, which is fabulous. It somehow fits close to the body while still having room for layers. I purchased the bitters color, which is a lovely dark neutral alternative to black and goes with nearly everything. The hood is big, as others have mentioned, but I LOVE it. It slides right over a hat. The neck does come up high but I also love that- it’s a good windblock (although a little fleece patch would have been welcome. Oh well. Not quite enough to take off a whole star). The jacket sheds light snow and the material seems durable- that’s actually why I purchased it- to replace ... MoreI’ve had this jacket for a couple weeks now, but it has been put to the test in our cold, dry snowy climate.

The jacket sheds light snow and the material seems durable- that’s actually why I purchased it- to replace a similar lightweight puffy that I was destroying. I have high hopes that this one will hold up to my abuses. I also love the two way zipper at the bottom. Overall this is a lovely all around jacket that I will use daily in our mountain town and pack as an outer layer on cold tours. It seems like it can do it all.
I had bought this jacket online and when I received it there were stitches that wasn't pressed against the jacket and pointy/hard. This made it really irritating to zip up since it would poke into my chin, and another spot where it irritated my hands when I put them in my pocket.I had gone into the store to confirm if this was an issue with every jacket or just mine but it turned out to be just mine. Due to such I was advised to open a support ticket online. I received a shockingly unexpected response and was told that the stitching issue was due to wear and tear and they would not support me. I felt that this was unfair as I had only worn the jacket once and if that's enough to be considered wear and tear then I really don't have high expectations of this product ... MoreI had bought this jacket online and when I received it there were stitches that wasn't pressed against the jacket and pointy/hard.

I would like to say that it feels very sturdy outside of the quality issues.
Super disappointing - Arcteryx made the sleeves so short on a Medium? every single other Medium Arcteryx I've purchased fits appropriately (20+ pieces over a decade) - however this ONE hoody is about 2-3" short when you raise your arm. The body is perfect - hip length perfect - hood fit perfect - SLEEVES awful ... this is winter jacket ... why make the sleeves SOFA KING short??!!Total miss. HUGE oversight. Terrible execution for an otherwise great hoody.
Brought this piece for my lady and she is absolutely pleased with it. As a stand alone she says it’s great, coupled with the kyanite hoody. It’s comparable to a suit of armor. Warmth, stand alone in 25-30 degree Fahrenheit with a windchill and a real feel of 20 does the trick just fine. We’re both pleasantly surprised by its pack ability. Only complaint is the hood, but to be honest it just may be knit picking at that point. She said and I quote “I wish the hood and the collar wasn’t attached.” Other than that great jacket. Maybe the only down you would want to own outside the Cerium.
The length is good, covers my butt.Sizing is good, generous.Warmth is good.Here's what I don't like:First thing: Fabric is see through. It is not white. Looks like camo. Can be a style, if that's what you're going for. But definitely not white. Only the shoulders and cuffs are really white. I think they doubled on the material in these spots.Second thing: I don't like that the logo is not on the chest anymore (but it still is on the men's version??).Just put the logo back where it was! Not on the sleeve, not on the cuff, not on the hood - on the chest!!Third thing: collar definitely is an irritant. You can't not zip it up, it doesn't lay down properly.Honestly I think I'll return for these reasons.
Just one thing bothers me on this jacket - I wish the waist was 1.5 inch wider and roomier overall - its too snug for athletic build 5'9". Right now it is 21" wide lying flat - it would be perfect if it was 21.5 - 22" wide flat. its difficult to have decent movement, especially when sitting down - just feels constraining like a girdle ! And I am not fat at all, just a bit stocky and 50. Going up a size doesn't work, where everything else becomes too big. Since this is not the cerium, primarily to fit as a middle layer under a shell, there is not reason to keep the midrift tailoring so snug - so relax it out an 1" overall next season please!
I bought this coat because I needed something warmer than my arcteryx atom. I like that the hood covers your whole head and the length is long enough to just cover the butt. It keeps me nice and warm. The only thing I wish, is that they made the shape of the coat slightly more flattering. It's quite boxy. It also fits larger than other arcteryx styles. I'm an xs in the atom heavyweight, but in this coat an xxs would have had a more flattering fit, unfortunately because of the boxy shape, I had to purchase the xs to make sure it would fit around the hip area, leaving it quite spacious around my upper body.

Exceptionally versatile, hard-wearing and warm, the Thorium men's hooded down insulated jacket can be worn as a warm mid-layer or standalone piece for cool, dry conditions. Its regular fit is streamlined and layers easily under a hardshell in cold conditions. The lofty 750 fill-power goose down gives incredible warmth for little weight, is durably resilient, and packs easily. Layering is the key of keeping you dry, warm and using your energy efficiently. Put into the right systems, a good sequence of layers moves moisture away from your skin, conserves or dissipates heat and provides you with weather protection. Here they are. The first layer, worn next-to-skin will provide warmth and quickly move moisture away from your skin. Then, the second layer, is the insulation and fleece, that provides warmth while also dissipating heat during periods of high output. And finally, the third layer, the shell, which is the most weather-protective layer, worn on the outside of all other layers.
