Matthew M.wrote a review of Arc'teryx Thorium AR Hooded Down Jacket - Men's on February 17, 2020
Familiarity: I've put it through the wringer
Fit: True to size
Arc'teryx took the REI Stratocloud (wish they still made those) and beefed it up. I've owned a bunch of down jackets and this is the best. 5 stars for versatility, warmth, breathability, THE HOOD, and good features. This is perfect as an outer puffy layer for winter 14ers, and is equally suitable for a nice looking down jacket on a cold night around town. Abrasion/weather resistant face fabric, packs down reasonably small, awesome hood, and is just so warm. warm warm warm. Wore this skiing in Colorado with temps in the mid to high teens, and the only thing I had on under was a 200 merino base layer. Was very comfy, and I tend to get cold easily.
If I had to cite a con it would be packability. It doesn't pack down quite as small as other jackets its size, but we're not talking about a huge difference here, and there's going to be a [minor] tradeoff for the burly outer fabric and small sections of synthetic insulation, which are nice to have btw. There is a clippable integrated stuff sack though which is handy. Also If you are tall maybe it will feel a little on the short side, but Im 5'6 and a medium fits perfect. Get this if you are looking for a very warm, all around down puffy.
