by fromTop Quality Down 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.

by fromGreat Jacket! A great jacket for daily use to and from work, and also great for weekend hikes with the dogs. The fit is great both in the body and arm length-I would highly recommend this product!

by fromSuper Light I wanted a ridiculously light jacket for all manner of activities. This was does the trick. My wife thought the box was shipped empty. For it's size it's quite warm. Packs down really small. Will be perfect for cool and dry camping.

by fromGreat all around down jacket Great mid layer down jacket. Heavier and warmer and more durable than a Patagonia Down Sweater yet not as heavy as some of the down jackets out there that can cause you to overheat. Great quality and nice fitting and feeling down jacket with synthetic insulation strategically placed.

by fromArc'teryx is dangerous to your wallet Had a tough time deciding between the hooded version and this one. I decided this one would be better because it's a little more casual and can be worn around the office. If needed, I'll put on a beanie. So far, I've only tested it in lower 40's in wind/rain (live in Seattle). In these conditions, I absolutely love it. I feel "room temp" when wearing it. Never too warm or too cold. I have a giant North Face down jacket as well that I'm always too hot in. This one has a nice balance. Another thing I like about this one compared to other down jackets out there is that it doesn't have that odd shiney look. I now own two Arc'teryx products. I'm blown away by the quality of Arc'teryx and while it costs a lot, I feel that it's so well made that it last a while. I high recommend this for anyone looking for warm casual jacket and doesn't want to feel "bulky" and uncomfortable. While I know this isn't how Arc'teryx intended this product, I haven't tested it in hiking conditinos yet so I can't really comment on that. But it's amazing for casual wear. Maybe I'll update my review later once I go hiking.

by fromMy favorite jacket ever I researched this jacket purchase a lot and finally came to the Thorium AR. I tried it on in the REI store and could immediately feel the quality that Arcteryx is known for. The fit is unbelievable; I feel like I'm not wearing anything when I move around. It is super warm but not too bulky and awkward. It looks great; my girlfriend loves when I wear it. And finally, the outer fabric is strong enough that it wasn't ripped the other day when I was out volunteering at Habitat for Humanity (carrying sharp objects sometimes). I chose the blue style because I like the two-tone style. The two-tone is where the synthetic fill is used. Great idea! I'm 6'0" 215lbs and the XL fits me well. Like I said, I love this jacket. I wear it almost every day now. I couldn't say a single bad thing about it.
