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.

Chest / Bust - Measure around your chest / bust, holding the measuring tape under your armpit.

Waist - Measure around the natural waist, which is often the narrowest part of your waist.

Hip - Measure around your hips at the widest part.

Sleeve Length - With your arms in a slightly bent position, measure from the center of the back of your neck, along the length of your arm, to the wrist.

Inseam / Pant Length - From a standing position, measure from your crotch to your ankle.

Head Circumference - Measure the full circumference around the widest part of your head.

Hand Length - Measure from the tip of your middle finger to the base of the palm.

Hand Width - Measure the circumference of your hand around the knuckles, excluding the thumb.

• Please note that all the info provided above refers to body measurements, and NOT the dimensions of the garment.


Next to Skin Fit - These snugly-fitting garments are made with stretch fabrics to fit next to the skin to enhance moisture management and thermal efficiency. Garments in this fit category when constructed using Arc'teryx's heavier-weight AR and SV fabrics also perform very well as mid layer pieces, and users should consider selecting a larger size to accommodate a base layer underneath if the intention is to use this layering system as a mid layer option.

Trim Fit - Trim-fitted garments share the motion-friendly traits with Arc'teryx "Athletic" fit garments, but are patterned with lower volume for reduced bulk. These close-fitting pieces layer well under other garments.

Athletic Fit - This is the "Arc'teryx Standard" fit. These complete patterns utilize anatomical shaping and gussets to enhance motion by minimizing excess bulk. Easy layering under or over each item extends seasonal versatility and comfort.

Relaxed Fit - Relaxed fit garments rely on higher volume patterns and a reduced amount of articulation to offer roomy mobility.

Expedition Fit - Cut roomier than the Arc'teryx Athletic fit and suitable for winter/extreme conditions, Expedition (XPD) fit garments are cut larger to accommodate multiple layers without binding or restricting movement.

• You can find the fit type and additional fit info for Arc'teryx styles in the product description FEATURES and SPECIFICATIONS.

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 4 out of 5 by from Great Purchase with sale price I bought 1 month ago and have worn it in temps 20 below zero and it still kept me warm. It also works great underneath a shell and can pack super easy into its own pocket pouch. My overall rating isn't a 5 because I have had small feathers of down stick out of the jacket that I have needed to pull out. I wouldn't recommend skiing in the trees with this jacket as it appears that a branch could rip the outer shell. Not sure on the overall durability yet but again...super warm and comfy.

Rated 5 out of 5 by from Best down jacket so far. I don’t want to repeat all the good things that previous reviewers have said regarding the Thorium AR jacket. Sufficient to say that they all are right. This is a great jacket; you will not regret buying it. It is great as an out layer for spring and autumn, even in rainy winter days. On real extreme condition, this jacket will work as a very proficient mid layer under a water and wind proof shell. Design, cut and fit were very well thought.

Rated 5 out of 5 by from Great Mid-Layer or Stand alone outer Our winters are usually mild, but occasionally it can get pretty cold. Of course, then the next week (or next hour) it changes, so I hate layering up. I also wanted something a little more durable that the ultralight puffers because the material on those seemed so thin. This jacket was the answer for me. I've worn this at 45 degrees with nothing but a cotton t-shirt, and I felt great. It's got good wind protection, too, as I noticed that only my face was feeling the sting. The water-resistant coating is nice as I did get caught in some light rain with no problem, but you'll definitely want to have a waterproof shell over if you know the weather is going to be bad. I'm 6'0, 180 with an athletic build, and the medium fits me well. I could still wear a long t-shirt, thermal/compression base, or maybe a sweater under it if I wanted to. Catch this on sale, and you won't be disappointed.

Rated 4 out of 5 by from Slim fit Jacket is well made and performs admirably. I wanted to keep it, but the slim fit just didn't work for me. The XL was comfortable around the abdomen but long in the sleeves and hem. The large was snug in the torso and shorter in the sleeves and hem (which works for me) but too roomy in the chest. I think Arc'Teryx is made for thinner people. I will have to buy Patagonia.
