Product Description Item No.   10281299

The Arc'Teryx Men's Thorium AR Hoody is a hooded down jacket for all round activities in all round cold weather. Multi-functional, as it can be used as a midlayer or a standalone, thanks to 750 fill European goose down to keep you warm. The shoulders, hood and cuffs feature Coreloft™, to help deter moisture where it builds the most. The athletic fit and hip length fit easily over your base layer and a hard shell pulls over top when the wind, rain, or snow are just too much for it to handle. Simple elastic at the hood and cuffs are small but mighty, wrapping against the body to prevent drafts and a hood from flapping around behind you. Two zippered hand pockets make ample space for extra gloves or a set of those disposable hand warmers, plus a stuff sack has been placed inside. When it's too warm for all that down, stuff the whole thing into the included sack and toss it into your pack for later.

Products on Sale are Discontinued Styles or Colors.

DWR tech

Durable Water Repellant
DWR (Durable Water Repellent) is a coating that is applied to fabrics which makes them water-resistant, or hydrophobic. A DWR finish doesn't interfere with breathability, which makes it perfect for adverse conditions in the backcountry.

Rated 3 out of 5 by from Good but... Good looking garment, warm, excellent fit, but the feathers constantly get out. I dont know if because the seams are too big or is a fabric problem, but every time I wear it my under layer is covered with feathers. I own another jacket from a japanese brand and I dont have any problems with the feathers. Honestly I dont expect this kind of problems with a product that is not cheap. Another issue is the hood design when is windy if the zipper is not completly up, the back of your neck freezing.. I hope that review helps to make some improvements and soon we can see a new Thorium AR 2.0

Rated 5 out of 5 by from Best down jacket even from Arcteryx themselves To start, I am 5"10 175lbs and a medium thorium fits like a glove. There is enough room to fit a fleece and articulation is great. Two reasons why I picked this jacket over the cerium LT are...1. The zipper is the plastic vislon that is used in almost all their hard shells. The cerium does not use the same zipper. 2. The face fabric is 40D over the 20D in the cerium. Overall this jacket fits under my alpha lt with no issues and is so light that I can't even feel it. Great jacket yet again.

Rated 1 out of 5 by from Sub-par The fit of this jacket is great. Besides that it really doesn't add anything to similar products already on the market (I also have a RAB alpine microlight, MH Ghost Whisperer and Patagonia UL down sweater) It's useless as a standalone outerlayer because of the sewn-threw stitching closing the baffles are exposed, so wind passes trough these holes, as well as the main zipper (only covered by a thin flap). Also, the baffles are rather big, and the down has shifted to the sides on my lower back, leaving cold spots. My copy also absolutely bleeds down. I'm still regularly picking my undershirt clean of a big handful of feathers. Not what I expected from an Arc' product. I will stick to other companies for down insulation.

Rated 5 out of 5 by from Great approach....VS Cerium LT To start i have both the Thorium and Cerium. I am 174cm with a 92cm chest and 33" waist measurement. The fit. I went for a Small on the Thorium, which is exactly like a Medium on the Cerium. The Thorium has a more relaxed fit compared to the Cerium's trim fit. I can easily wear my Rho baselayer and Atom LT unferneath with no problems, whereas on the Cerium, it feels restricted with layers on. The sleeves and the length on the Thorium are also slightly longer. Adjustments. There are NO hood adjustments on the Thorium whereas the Cerium has one. I do not find it a problem since the Thorium has a much cozy hood and coverage is awesome. It also has a slightly higher collar than the Cerium. There is one single drawcord near the hem on the Thorium, which does NOT exist on the Cerium. Personally i think the drawcord is a must to trap winds, especially for insulated garments. The zippers. Main zipper on the Thorium is identical to the one on the ATOM series. Beefier than that on the Cerium. Good thing about it is that it does not unzip itself in windy conditions like the one on the Atom. Meanwhile the main zipper on the Cerium is tiny. Zipping thr jacket up is just a pain. The feel. The Thorium has a much more cozy feel, but it does not make you look like a tyre man or as bulky as jackets like Canada Goose. Sure it might not be as warm, but for a lightweight down jacket it does its job perfectly. The outer shell definitely feels stronger. Veredict. The Thorium is my everyday choice unless you are obsessed with super lightweight gear (Cerium). It has a better zipper, stronger outer fabric and a slightly relaxed cut.

Rated 5 out of 5 by from Fantastic mix of down and synthetic I took this jacket up to Killarney in Ontario last weekend, it performed great! Everytime I washed up and splashed water on my cuffs, and everytime I put on my 50 lb pack, I was grateful for the coreloft. I was very biased in favour of natural materials like down, but the design of this jacket has changed my mind. Highly recommended! Fits really well, and quite stylish too!

Rated 3 out of 5 by from Great design, but sheds down. As other reviewers have noted, this product is quite well-designed and very functional but with one critical flaw. What what I can see, smaller feathers are finding their way out of the pockets from the small holes of the stitching where the thread goes through. I've only owned this jacket for a day, and have already had to pick 10-15 feathers off my base layer. I'll see if this rate slows down over the next couple of days. If not, I'm going to return it.

Rated 4 out of 5 by from Warm, comfortable, and great looking piece that needs some improvement. I've been wearing this piece for a about two weeks now for a variety of activities and it's quite nice. The medium fit me perfectly (i'm 6ft, 175lbs). It allows for a t-shirt and 100 weight fleece to be worn underneath without any restriction in movement. The outer fabric isn't shiny which i really like and the inner fabric is silky smooth.I had my doubts about the coreloft placements but the hood is really quite warm. I spent 6 hours in 40 degree weather (being sedentary) with just a long sleeve tee as a base layer and felt warm. My only qualm with this jacket is the feathers which have been popping out from the inside of the jacket. The leakage is happening at the hems and has been substantial for the two weeks I've had this piece. From what I've found on my shirts I lost somewhere around 20 very small down filaments (about the size of a thumb nail) and about 5-7 larger feathers (2 inches+). This is not ideal and it wasn't something I expected from an Arc'teryx piece, especially since my Mont bell jacket which was half the price has never leaked a feather in the years I've had it. Hopefully the shedding does not continue!

Rated 5 out of 5 by from Excellent Mid-Layer I don't understand what some of the reviewer's are complaining about. I love this jacket. I bought it to use as a mid-layer under an arcteryx shell. What do I consider makes it a mid-layer? Elastic instead of Velcro cuff cinches. No cinching for the hood. Both were features I specifically looked for. How does it do in the rain? I have no idea because I throw on a gortex shell in that situation. If I ever decide to use it in the rain I'll hose it down (carefully) with a serious marine grade DWR but I'm not seeing a need for it. What I wasn't expecting when I bought the Thorium was how well it does in the wind. Its been 15-20mph winds and temps in the lower 20s for the past few days where I live, and the Thorium has done very well without a shell. This is due to the very fine tightly woven rip-stop fabric I'm sure. I've not seen a fabric like this before. Its like four times more dense than the typical rip-stop squares you see on other jackets. I haven't seen a single feather shed from it either. So see this jacket for what it is and what it isn't. I can't recommend it as a shell, but as a mid-layer its the bomb.

Is this jacket warm enough as a standalone if I wear a cashmere sweater inside with weather in the teens?

Asked by: zuffy
Hey there, Everyone has a different opinion about how cold is too cold, so this is always a difficult question. I can tell you the Arc'teryx Thorium "AR" Hoody is intended for all round ("AR") activities in all round ("AR") cold weather, hence its name. It can be used as a mid layer or a stand-a-lone thanks to the 750-fill goose down. High-fill power goose down ranges from 550 to 900 fill. The higher the fill, the warmer the jacket.
