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 4 out of 5 by from Good fit, Versitle design I generally run on the smaller side for guys and was contemplating between this and the Cerium LT jacket. Ultimately, i went for this because it feels more robust and has a cinge cord at the bottom of the jacket. This jacket feels like it can be used for anything, from hiking, belaying to using it for casual means in the city. Paired with a patagonia fleece, it worked great for temps under 20F. I'm 5'6" and 130 lbf. Small fit nicely on my shoulders as a layering top with ample space to layer beneath. Jacket could do with more pockets though. Especially an inner check pocket.

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.

How do I contact them with questions?

What is and isn't covered under the Warranty Policy?
Defects in materials or workmanship are covered for the practical lifetime of the product. Material refers to zippers, buckles and fabrics. Workmanship refers to seams, seam tape and construction. Damage due to wear and tears such as rips, tears, abrasion or UV degradation, misuse or neglect is not covered under Arc'teryx's warranty policy but may be repairable for a fee.

What is covered under the Warranty Policy on Arc'teryx footwear?
Defects in material and workmanship will be covered by Arc'teryx for the practical lifetime of the product. The practical lifetime for footwear can vary drastically depending on the frequency and type of usage. Things such as the wearing of the outsole, frayed laces, nicks and tears can indicate that a shoe has surpassed its practical lifetime. These are examples of wear and tear or damage which are not covered by Arc'teryx. If you believe there is a defect in material or workmanship present on your product, please see follow the instructions on how to send it to Arc'teryx for assessment.

What does 'practical Lifetime of the product' mean?
Although Arc'teryx builds their products to last over extended periods of time, nothing lasts indefinitely. Materials will deteriorate and fade over time and moving parts will wear out. Arc'teryx will cover your product under their warranty policy until such a time that they have deemed the product to be worn out beyond reasonable repair. If the product is showing the signs of its age-for instance, the material has become thin or faded, there are rips and tears, the zippers no longer catch, the cuffs are fraying, or the soles are worn-they will take this into consideration when assessing your product for a warranty request. All gear will suffer from differing degrees of wear-and-tear, depending upon the user. Equipment used by an outdoor guide for 150 days a year will by comparison, degrade faster than gear used by a weekend skier. By taking care of your equipment you will ensure a longer lifetime for your gear. Arc'teryx recommends that you visit their Product Care page for more information on how to wash and care for your equipment.

Will Arc'teryx repair or replace my product?

They have repair centers in both Europe and North America that employ the same custom machinery and techniques that they use to create the original products. If the product is not repairable, or the cost of the repairs exceeds the value of the product, Arc'teryx may, at their discretion, choose to replace the product instead.

What happens if I rip or tear my jacket or pants?
Skis, snowboards, crampons, axes and other sharp equipment will damage clothing and gloves if they come into direct contact with them. Rips, tears, burns and punctures can occur during normal use and while carrying your equipment, and are not covered under the terms of the warranty. To assist you in keeping your product in optimal working condition, Arc'teryx offers a variety of repairs for a reasonable charge. Contact them and they will be happy to discuss your options.

What if I want to have my garment altered or tailored?
Arc'teryx does not offer custom alterations or modifications to their packs or garments at this time. For products made from GORE-TEX® fabrics they suggest using a GORE-TEX® authorized repair facility for alterations. There is a list of GORE-TEX® authorized repair shops in your area on the GORE-TEX® website.

Do alterations void my warranty?
Arc'teryx understands that individuals may, on occasion, wish to tailor their Arc'teryx products to suit their needs. If something should fail which is unrelated to any alterations, Arc'teryx will stand behind their products, provided that the Arc'teryx product is being used as intended. For a list of alteration facilities in your area, please visit the GORE-TEX® website.

How long will it take if I send my product in for warranty assessment and/or repair?
The typical turn-around time is 15 to 20 business days from the time they receive your product to the time they ship it back to you. Keep in mind that winter is the busiest season for warranty and repair service. Arc'teryx will provide you with updates and more accurate estimates throughout the process.

How do I prepare my item for return to Arc'teryx?
