Product Description Item No.   10281294

The Arc'Teryx Men's Thorium AR Jacket is a down jacket for all round cold weather outdoor exploration. On a hike over the weekend or a multi-day adventure into the backcountry and the 750 fill power grey goose down will turn into your best friend. Mornings and nights can be quite cold, and even midday depending the day or season, so throw this on as a midlayer or even a stand alone. Pitch your tent or tear down camp in cozy upper body warmth, then hike a spoke or take off to the next camp. As a stand alone piece, the shoulders and cuffs use Coreloft™, a synthetic insulation, to combat moisture-prone areas, since you never know when a little sprinkling of rain might happen. Zippered hand pockets warm up the hands along the way or secure small items for quick access and when the weather or your body heats up enough to ditch the down, the whole thing packs into its very own stuff sack. Oh down, so compact when packed, so fluffy when worn.

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 5 out of 5 by from Well made, great fitting down jacket with innovative features The fit of my Thorium is perfect for me. There is a little room in the body to allow for a layer underneath. It pairs well under my Arc' hard shell. I own a few other Arc' pieces and sometimes the sleeves seem too long but not with the Thorium. What particularly impresses me is the breathability of the jacket. For example my Atom LT which I love too heats up when I'm working hard in it and sometimes feels too warm whereas the Thorium in similar conditions seems much more breathable and overall more comfortable. Each jacket has its time and place and I see the Thorium as great add to Arc'teryx' lineup. The jacket is well made and feels a step up in terms of look and feel of other down jackets. I'm sure I will be happy and wearing this jacket for years to come.

Rated 3 out of 5 by from Zipper is not great This jacket looks very nice and is quite warm. Two Minor Complaints: 1. The zipper comes undone very easily. I had my jacket done up about 2/3rds of the way and had it come completely unzipped when hit with a hard gust of wind. 2. The XL fits me nicely around the chest, shoulders and back but the hips/waist is really baggy. It has a waist drawstring so that helps to make it look like a more tailored fit. As Arcteryx shirt/jacket sizes get bigger than a medium they slowly get proportionately larger around the waist vs the chest. From Large to XXL the waist to chest ratio increases more and more. I'm 6' tall, weigh 192lbs with a 44.5" chest and 32.5" waist and the XL is the size that fit me the best.

Rated 4 out of 5 by from A triumph of function over form If you are purely after an understated jacket that has excellent thermal properties, with no unnecessary weight- then you should adjust my rating to 5. I think the jacket could be a bit less Spartan however with only a small weight penalty. An inside pocket wouldn't go amiss and I'd much prefer the sleeve cuffs to be less insulated (less puffy) on the lower forearms and wrists. The problem is that unless you have very long arms, the material bunches up over your cuffs- meaning you get your sleeves wet for example when washing your hands. Otherwise the jacket is clearly well put together and well thought out and the warmth to weight ratio is excellent. The jacket has a fantastic weight to warmth ratio and fits the Arcteryx modus operandi of making garments for purists- not posers.

Rated 3 out of 5 by from light and warm but for how long I bought this jacket to go along with a shell jacket for skiing. Great, light jacket, very harm, and blocks some wind. I wore it during a couple of windy days and it was great. However, after just a week of having the jacket, there's lots of feathers coming out of the jacket. At this rate, I wonder how long it will take before all the down is gone.

Rated 5 out of 5 by from awesome jacket I have come to really appreciate Arcteryx gear over the years and first saw the Cerium at an outdoor show. My first thought was that I wished they had made it with a more durable exterior fabric and 750 fill (I tend to roast in 800+)...then I discovered the Thorium. While the Cerium is extremely light and probably ideal for that packable, occasionally used mid-layer, the Thorium is more for for daily use and seems superior for dual purpose (standalone wear or mid-layer). The cut is a little less fitted, the zippers feel more robust, and the 40d face fabric is definitely more abrasion resistant than the Cerium. It's exactly what I was looking for, and it's highly price competitive too.

Rated 5 out of 5 by from This jacket is an excellent piece of kit This is not a bulky or a typical "puffy coat" it is light weight and can be worn under an outer shell. It was an extremely cold winter in upstate NY this past year and you will be able to wear it as a standalone in sub zero weather.

Rated 4 out of 5 by from Good mid/outer layer, but I wish it was longer! Attention to detail and quality are excellent with this jacket. The stitching is extremely tight, and I have yet to have anything go wrong with construction. The 750 fill is adequate between 20-50 F - by adding my Arc'Teryx Beta LT on top, I can easily take this combo down to 0 F. I chose this over the Cerium LT because of the more robust face fabric, waist draw cord, and the added protection behind the main zipper. My only complaint thus far has to do with fit. I am 6'1" 180 lbs. and wear the Medium. The chest and torso fit perfectly, but the sleeves and length seem to be about 1 inch too short. From what I understand, the jacket length was made shorter to accommodate a climbing harness. That being said, perhaps it would be ideal make the Cerium LT harness compatible (since it is marketed more for alpine-use), and keep the Thorium AR a bit longer (since it is marketed more as an all-around jacket). I should also note that I do not have this problem with other manufactures (TNF, Patagonia, etc.), although I like to stick with Arc'Teryx because I think the quality is much better. Overall, the Thorium AR is an excellent jacket for alpine and urban use. For me, it would be PERFECT if the sleeves and overall length were one inch longer. A slightly taller collar would be a welcomed addition, as well.

Rated 5 out of 5 by from Solid Insulating Jacket I chose the Thorium AR to use as my main base camp piece. It's big enough to keep warm in cold conditions, packs down small enough that it doesn't take up a ton of space and is versatile enough to layer up or wear on its own. I also prefer the larger zippers than what is used on the Cerium's because they are easier to grab with gloves on. Great coat! PS. I also use it in a larger stuff sack to double as the perfect size pillow!

How do I send back an item for Warranty, or get an item repaired by Arc'teryx?
For Customers in North America and Europe, Arc'teryx recommends that the product be returned to the store or site where it was originally purchased.

If this is not possible, fill out their online warranty form which can be found HERE. They will email you with full instructions on how to send your product to their Warranty and Repair Center. Do not send your item to them without first obtaining an RA number from Arc'teryx.

Arc'teryx is not responsible for items that are lost or damaged during shipping and cannot replace parcels that are lost during return shipment if proof of tracking is not available. Please use a guaranteed delivery service that provides tracking information, insurance, and proof of delivery when sending an item back to Arc'teryx.

For customs purposes, Arc'teryx requires you to provide them with a PHYSICAL address, however, your warranty/repair item can still be shipped to a PO Box.

How do I contact them with questions?
Complete their Warranty or Repair Request Form. If you have any questions or concerns, you can reach their Customer Service department at 1-866-458-2473.

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?
If your Arc'teryx product fails due to a manufacturing defect, where possible, Arc'teryx will repair the item at no charge to you. 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?
In order to comply with health and safety regulations, as well as for the protection of their staff, Arc'teryx kindly asks that all products be cleaned before being sent to them. Products that arrive unwashed may be subject to a cleaning fee before assessments can be made. To find out how to properly clean your garment, please visit the Arc'teryx Product Care page.
