The Arc'teryx Men's Thorium AR Jacket succeeds at giving you maximum warmth and versatility in a mid-layer while limiting weight. They have expertly mapped two different types of insulation across areas of need: Coreloft synthetic in moisture-prone zones (hem, collar, sleeves and underarms) and 750 fill down in the core and arms. With such mapping precision they should have called this the Rand McNally Jacket.... but Arc'teryx never listens to my jacket name suggestions. The DWR (Durable Water Repellent) finished exterior will shed some moisture so the Thorium AR can handle itself on its own, but really shines as an insulating layer under a shell.

"Very light and practical with great balance of 750 goose down and synthetic insulation"
Thorium AR jacket is not 100% down but has synthetic Coreloft insulation strategically placed in the shoulder and collar areas. Such mix makes the jacket very attractively priced and very practical as the synthetic insulation resists moisture and dries much faster than down itself. When folded into it's sack it has a very small footprint and extremely light. A great light weight semi-down jacket to carry around any time.
I did some serious researching when I decided I needed a down jacket. Selecting this jacket was an easy choice after reading many reviews regarding this item. There are a few good companies out there that make a solid down jacket, but Arcteryx took the cake. The craftsmanship is absolutely spot on, I can't count the multiples compliments i have received when wearing this jacket. I was having a hard time between the Thorium and the Cerium, in the end the durability was the final factor for me to select the Thorium. The Thorium has a more durable face fabric then the Cerium, which will hold up better for hiking and using as a outer piece for skiing or snowshoeing. I've managed to stay very comfortable with this jacket and a R1 fleece in 20 degree weather.You can use it as an outer piece around town or on the trails or you can use it as a mid layer with a hard shell and be super toasty. I would absolutely recommend this piece to anyone that wants a functional and stylish piece
"Light, warm, foxy! What more do want fool?"
If you're spending this much on a jacket, you want it to look good. This one does. You want it to be warm too, eh? Well this jacket is super warm even though you can barely feel it on your skin because it's so light. So now you're walking around looking hot and sexy and lightweight...like someone who has the "function plus fashion" thing nailed. You're life is almost complete. Now put some pants on and you're all set. Winner.
I can't believe how light this jacket is yet it is SUPER warm. I wore it all through the record breaking 2014 Michigan winter and it held up great. fit is good and pretty true to sizing, or possibly a little small. one thing I noticed is that the material is a little more "shiny" than the photos seem to show. other than that, another fantastic jacket from arcteryx.
"Arcteryx's first down offering is a success!"
Was debating between the Thorium AR and Cerium LT for a bit. Finally decided to go with the Thorium for the more durable 40D Colibri face fabric and slightly less trim fit for layering, since I plan to use this as an outer layer when a waterproof shell isn't needed. If Arcteryx stuff fits you well this will fit right in with the rest of your collection in the same size. Nice athletic fit but provides good movement and some room for layering. The face fabric is very low sheen, which I like. The inside fabric is shiny and smooth and feels nice on the skin. The minimal puffiness keeps you from looking like the Michelin man. The jacket is so light doesn't even feel like you have a jacket on. It's been below 32F in NY the last few days and I've used it with just a t-shirt under and it kept me nice and toasty walking around the city. I was surprised that it does a good job of keeping the wind out too. Love this jacket!
Best down I own - have a Pat high loft but I always prefer the fit of Arc better - whether it's sweaters, jackets, etc. True warmth w/ no weight or bulk. Minor irritation -when zipped up, there's a big dimple in the center of the jacket where the inside lining materials meet, causing a 5" puckering of the zipper and shell visible from the outside. Picture a 5" belly button just below the sternum. Just gives the appearance of poor tailoring/sewing. Not a deal breaker but I pay a premium for Arc because I expect a premium attention to detail. I hope it's just flaw with my jacket and not how every Thorium turns out.
There's a reason I always return to Arcteryx for outdoor clothing - the quality of material and construction. I tried this down jacket for a 3-day backpacking trip to the Smokies and it was perfect. The athletic fit allows good movement, even with a backpack, and the provided stuff sack is convenient when you need to peel a layer. No cold/hot spots and the loft didn't shift around inside the fabric. This jacket does run a little tight; so putting fleece layers underneath makes for a really snug fit which may bother some folks. Exceptional quality with the workmanship (seams, zipper, cuffs, etc.) and the fit all around is true to size.Great Moosejaw customer service (as expected & received)
