Arc'teryxThorium AR Hooded Down Jacket - Men's

Packable heat.

From staying comfortable on a windy belay ledge to warming up your climbing skins before you head back up the skintrack, the Arc'teryx Men's Thorium AR Hooded Down Jacket provides necessary warmth when you're at rest. Providing a high warmth-to-weight ratio, 750-fill European goose down through the core and arms of the jacket deliver on-demand warmth, while water-resistant and durable Coreloft insulation—crimped and siliconized polyester yarns—maintain heat in areas prone to wetting out if you decide to wear the jacket when you're on the move. An insulated StormHood brings the the heat up to your head to prevent heat loss while you're at rest, and the elastic cuffs and drawcord hem help to seal the warmth in around your core.

Mount Kilimanjaro

  • Fit: True to size
  • Size Bought: M

My dad is hiking Mt Kilimanjaro, and wanted to ensure he had a down jacket that kept him warm all night long during the ascent!

Chatted with my Gearhead, Emily Brown, and she couldn't recommend this jacket enough!

AMAZING

  • Familiarity: I've put it through the wringer

This jacket is close to perfect! I wanted something for everyday use that wasn't going to be very bulky but still keep my warm. This jacket fits me great, I am 5'8 170.

I love the hood, it snugs up nicely when zipped all the way up but I can still wear a headlamp with out an issue. I would highly recommend this piece!

Unanswered Question

I'm wondering how this jacket compared to the Mountain Hardware Ghost Whisperer down jacket. I'm looking for a highly packable down jacket, and I've narrowed it down to these two, but I'd like to know how they stand up to one another. Thanks!

Very close to perfect

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: XL

Great length, True to Arc'teryx size for me (XL for 46L jacket, 38" waist), perfectly warm in breezy windy teens over LS 150 merino baselayer and not too hot when it's up to 40. Perfect under a shell when it's colder or wet. Great length. Only niggle is no adjustment on hood. It fits well, but an adjustment to snug the hood around the crown of the head would make it perfect. Packs nice and small, about Nalgene size, and very low weight.

If it ain't broke, don't fix it!

Please don't ever change this jacket Arc'teryx! Absolutely love it. It is great for a night around Park City or out on the trail snowshoeing with the family. Perfectly lightweight, super warm, great fit and love the hood. You aren't going to find a better down jacket out there to do it all!

Great for everything

This is my favorite down jacket from Arc'teryx for many reasons, first is the quality of down they use, it is a 750 fill euro goose down so the best of the best. In addition to great down insulation it also features coreloft insulation that will ensure that you stay warm even if the down gets soaking wet.
If you are looking for a down to do it all, look no further. This is the jacket that is recommended for around town use, as well as for skiing, snowboarding, ice climbing, or whatever your passion. It fits true to size for Arc'teryx, with articulated arms for a comfy fit.

Warm!!!!!!!!!!!

This jacket is awesome for every part of winter! I recommend getting a size larger than normal they fit really snug. I rock mine in the cold winter here in Italy and it does an awesome job on keeping me toasty. It is super light weight and packs down to almost nothing.

I'm confused with the sizing on this jacket. Is athletic fit the same as trim fit? Where does this jacket fall on Arcteryx's sizing chart?

Hey James,

The athletic fit is very similar to the trim fit, but provides a little more room in the shoulder and pec area - providing a little more room for an athletic-built body. The main benefit of an athletic fit jacket is that it is crafted for ultimate movement, so it's great for physical activity. As for how the jacket falls on sizing, here's a photo that compares the fit and look of this jacket compared to other similar jackets in Arc'teryx line.

There is a sizing chart listed right above where it says "select a size" above, but let me know if I can help you determine the best size for your height/weight and measurements!

Warmth without weight

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: Large

This is my first Arc'teryx purchase, I was considering a The North Face jacket and decided on this jacket after chatting with a Back Country rep. Although I reside in a high desert city, it still gets cold and occasionally it snows. My LL Bean Maine Wardens coat is too heavy and bulky, this jacket is perfect. I am able to layer with a fleece jacket when the temperature dips below 32 degrees for added warmth. I am very pleased with my purchase and with my Back Country experience.

Looking for a jacket to replace my old Marmot Ama Dablam (R.I.P.). I liked the warmth level of the Ama Dablam since I often used it as a casual standalone piece, so I want a replacement that doesn't require layering when I go to my office job in the winter but also doesn't make me look like a giant puffball. Is the Thorium AR going to be noticeably warmer than the lighter weight jackets like the Cerium LT, Patagonia Down Sweater, MHW Ghost Whisperer, etc? Or should I go back for another Ama Dablam or something else in that same range? Thanks for the help!

Hey Robert,

The Thorium AR is a warm jacket for it's weight and will provide much more warmth than the Cerium LT, Ghost Whisperer, and other lightweight down jackets. While the Ama Dablam may be warmer overall, the Thorium is a much slimmer cut that does not make you look like a marshmallow. This jacket is great for standalone use and can hold up to being a daily-wear jacket. For the next step up in warmth, check out the Thorium SV and feel free to contact me directly for sizing.

Warm enough for the beautiful places

I bought this jacket as a gift for a good friend who works bell service at a hotel in Sun Valley, ID at 5900 elevation. He stands outside a lot greeting customers so he needed a jacket that would be warm enough to keep him warm while stationary and versatile enough to keep him comfortable while moving heavy luggage and running around. This jacket has exceeded our expectations.



We've determined the temperature range for this jacket is minimum -3F to a more comfortable 40F with the sweet spot being between 15F to 30F. It has been snowing quite a bit in Idaho this season and the DWR treated down creates some water resistance for when he gets caught out in a light snow storm.



He also uses this jacket under a waterproof shell while skiing. Any cold winds that the outer shell lets through the Arc'teryx Thorium AR absorbs. It has a nice athletic fit that is super easy to move around in and extremely light weight.



Arc'teryx makes great technical gear.

Lovely jacket

    I love this jacket it's very lite and worm material good quality is stander very soft I love it

    First time buying

      Excellent jacket love it

      Great coat!

      • Fit: True to size
      • Size Bought: Medium

      Fits perfectly, is super light, and very warm. Both from a fit and functionality perspective, it is one of the best coats I have ever purchased!

      So cozy!

      This is an outstanding jacket. The fit is really nice. The length hits just at the top of my hip, and the sleeves are articulated which gives them a more contoured fit. I also love how high the collar sits. Pull the hood up, zip the collar up, and you'll stay nice and toasty warm.

      I've used this Jacket on its own and under my Mountain Hardwear Shell. In both cases it works very well and keeps in the heat.

      I haven't had any fill loss yet. But if I do, I'll follow the Arcteryx care guide instructions.

      Hello!
      I have a desperate question as need to purchase very urgently for an upcoming trip! My hesitations are between Thorium AR and Marmot Ama Dablam. Which one will you reccomend for colder weather and generally more use in the winter?
      Thanks

      The Thorium AR uses 100 grams of 750-fill European grey goose down. It looks like the Ama Dablam uses 800 fill goose down but I'm not sure how many grams(?)



      The Thorium is designed as a stand alone or layering piece and is my go-to winter puffy. It's extremely durable and fits incredibly well. I wear it daily around town and will layer with it on colder ski days.



      The articulated sleeve construction allows for a much nicer fit than a tube-type sleeve construction.



      The Thorium AR also features Down Composite Mapping - which uses synthetic Coreloft insulation in areas prone to moisture build up: hood, collar, hemlines, cuffs and armpits.



      If you're looking for the next step up in warmth, checkout the Thorium SV:

      I had bought `Marmot Megawatt `, the size S fit me perfect, so will the S size of Arcteyx fit me?

      Maybe - double check the size chart to be sure. The Thorium AR jacket fits true to size.

      Warm for the cold winter weather.

      This jacket is amazing. It blocks the cold burst of winds while I walk my dog on those cold frosty mornings. Very well insulated as it creates a nice warm pocket of air between you and the jacket. Zip down the pockets and stick your hands into toastyness! Who needs gloves when you have these pockets ? It's also super comfortable and I like the elastic bands on the wrist to keep air from coming in Overall very warm and comfy.

      What is the difference between the 2014 and 2015 models?
