Thorium AR Down Jacket

What's good for the goose is good for you, and Arc'teryx joins the feather-fete with the Thorium AR Down Jacket. It's a durable, flexible piece that combines goose down and Coreloft insulation to meet your winter outwear demands. Wear it to and from the office, hiking to the final summit of the season, or under a shell while blasting through waist-deep powder in single-digit sunshine. Regardless of how you spend your time, the Thorium jacket protects you from the cold, alone or under a hardshell.

The Thorium is a unique piece, using both synthetic and down insulation. The warm-when-wet Coreloft insulation hangs out in the collar, cuffs and under the arms, as these areas are more prone to moisture. The down insulation resides in the sleeves and the core of the jacket to give you body-hugging warmth on frigid days. Durable Colibri mini-ripstop nylon is treated with DWR, so when flurrying snow or light rain lands on the jacket, the water beads up on the surface rather than being absorbed by the fabric and soaking the insulation. It's newly updated to include a stuff sack so you can easily throw it into your pack, and has two hand pockets to keep your essentials close by. Whether you sit at the 50-yard line in Buffalo, sled with your 5-year-old, or snowboard with friends, the Thorium jacket keeps you warm, on its own or as a layer.

  • An innovative insulator to keep you warm in winter weather
  • Strategically place synthetic insulation stays warm when wet
  • Down insulation in the core to keep you warm where you need it
  • DWR treated fabric sheds off light winter precipitation
  • Included stuff sack lets you quickly pack it down and stow in a pack
  • Hand pockets offer a warm refuge and easy storage
  • Item #ARC00TS

It is the best warm layer for world adventure and business travels! It packed light and in comparatively smaller size. I easily get cold in many situations, this jacket kept me warm all the way! Totally love it!

Perfect Gift for Dad!

Familiarity:
I gave it as a gift but have feedback to share
Fit:
Runs small

We got this as a gift for my wife's dad and he loves it! He primarily uses the jacket for travel, around town, and to the office, but he loves it! We originally got him a Large, but it does fit a little small, so we ended up getting an XL, which fits him perfectly. If you are borderline with sizing, I would go up a size to be safe with this one.

Worst jacket ever bought from Arcteryx and backcountry should be ashamed selling it. The jacket magically unzips by itself and I love Arcteryx closet full of their stuff . Personally backcountry should give a free jacket to anyone who bought this and returned it.

The Thorium AR Jacket that I bought in April 2018 from Backcountry has the No Slip Zip feature with five separate "bumps" to keep the zipper from lowering on its own.

I ordered this jacket for my 14 year old son. Compared with other jackets, this one felt the most durable on the exterior and seems like it would be warm but the torso was shorter than the north face and too short for his 5' 7" frame in a S. A larger size would have been too long in the sleeves.

I carried (or wore) a Thorium AR for the entire length of an AT thru hike earlier this year. I used it underneath rain gear, by itself, and slept in it when it was cold. Although I didn't use it for about a six week stretch in the mid-Atlantic states, it came back out in New England, where some of the mountain tops can get pretty chilly, even in July and August. They feel even chillier when you have no body fat left to burn. The dual construction (down core, synthetic shoulders and extremities) might seem like a marketing gimmick, but it makes total sense in the humid East. I love this jacket. I'm 5'9, 168 lbs. with a proportionally longer torso and the medium fits perfectly. This is a garment for serious outdoor use, not urban wear. It's not magic and it won't keep you warm all by itself at -10 Fahrenheit with limited physical exertion. You'll need something a little puffier for that.

Much warmer than fleece under a shell

I received this jacket for Christmas and have worn it around town and on some backcountry ski trips. I have worn it a fair amount in cold rain under a shell (34-40 degrees) for work outside and it is quite toasty over a long sleeved shirt, standing around and some walking. I've used it as a lunchtime warming layer on ski trips in the Cascades and Olympics and have been impressed with how warm it is. On one summit in the Olympics it was about 25 degrees with a 15-20 mph wind and I was quite comfortable for the half hour lunchbreak (layered over thin fleece and thin long underwear). It is much, much warmer than a 200 wt. fleece jacket and way more comfortable, way more compressible and lighter too. I generally wear a rain shell over it if it is raining because I don't expect it to be waterproof. I was between a Lr and XL at 5'11" and 185 lbs, wearing it over some light layers. If I were only wearing a t-shirt a Lr could work. So the XL is roomy but works for my purpose. I found the fit trim in the shoulders, so I went up a size.

I decided to go with the Arc'teryx Thorium AR after much research to try and stay warm in upstate NY. Fitting: It fits to size. I am generally an XL with most companies, and Arc'teryx does tend to have an atheletic fit. That said, the jacket fits snugly without limiting my movement. I could likely fit a small/thin fleece under and/or layer over it with an overcoat if needed. Warmth: So far haven't put it through the ringer mid-winter, but it has kept me warm with just a T-shirt underlayer in 20ish degree weather. Style: As always, Arc'teryx products look good. I would definitely recommend this jacket.

Not warm enough.

I bought the women's version of this jacket. I was wanting something extremely warm to use for sub zero temperatures. It just recently got cold enough here in Fairbanks for me to test out the jacket. Sad to say, it is not all that warm, even at -10, taking the dog for a walk. It fits rather snugly (yes I bought the right size), so it's not possible to layer, except over, but not under. It's also noisy - gets "crinkly" on some inside layer in the cold, and makes a loud swishing sound when you swing your arms.

I'm really happy with the color of this, got the Atlantis green. It's so lightweight and the zippers are really nice and smooth on both the pockets and the main zip. I'm happy with choosing this and haven't used it much yet in 30 degree weather but I'm sure it will meet and exceed my expectations.

My first Arc'teryx jacket. I purchased this as a new jacket for wearing around-the-town. I am not using it as a technical piece, so I won't be speaking to that. Let's start off with the look. It looks GOOD. I got it in the Atlatnis Green color and it is amazing. It's really an amazing color. The athletic fit keeps it a little more form fitting, and less boxy, which I prefer. I'm 5'8.5 and about 145. I wear mediums in pretty much all jackets/fleece, and this is no different. I probably could have purchased a small, but I don't think it would have given me much flexibility with what I decide to wear underneath. Warmth-wise, it appears to do the trick. I have worn it in temperatures ranging from single digits to 35degrees. While I wouldn't say it is a standalone jacket for single digits, it did an admirable job when paired with a good mid-layer fleece. As to quality. it seems to be typical of Arc'teryx. The only thing I haven't loved is a little loss of down. It isn't anything crazy, just here and there there will be feathers on my shirts and fleece layers. Other down jackets I have owned have lost some feathers, but not as quickly as this. I love this jacket and would definitely buy again. If you are contemplating purchasing this, I would highly recommend it! It will look good and keep you warm while doing it.

Overall, this jacket is great. The jacket is super lightweight yet still so warm. The coreloft insulation in the shoulders and collar is a great call, and I still stayed warm when I got rained on unexpectedly. Arc'teryx has done it again, and never fails to impress!

I bought this jacket recently and it met all my expectations. I'm 5'9 150 pounds. The size small fits perfectly. It's warm enough that on most days I just wear a t-shirt underneath. I live in Vancouver, BC.

Arcteryx Thorium AR

Familiarity:
I've used it once or twice and have initial impressions
Fit:
True to size

Fit - In comparison with the Arcteryx Cerium LT Down jacket, I have this in a Medium and the Cerium in a Large and the fit is nearly identical. Construction - Overall feel is definitely more robust than the Cerium LT (which is how this jacket was designed) including the more heavy duty main zipper. While more robust, it is still fairly light and packable. Will definitely stand up to more rigorous use. Quality is on par with what you would expect from Arcteryx.
