The Arc'teryx Sigma AR Jacket is a four-season softshell designed for impressive adaptability in alpine environments.

Arc'teryx Sigma AR Jacket - Men's



Close to the perfect
My impression is that the Sigma AR is not as warm as descriptions might give impressions of - but that might be due to me misunderstanding these descriptions. Living in the most nothern part in Norway I was in need of a softshell suited for warmth. Still, it is an excellent softshell by any standard, and together with another fleece layering it will also work for temperatures down to -30 C. Particularly, I like the athletic trim and the underarm venting. This makes it a all-purpose shoftshell. For my purpose I would like a solution that could make the collar a bit more snugfit when in cold temperatures. When it comes to stretch-ability the Sigma AR is not as good as the Gamma SV. But these things should not take away the fact that this is a top softshell. There are a lot of excellent functional small-detail solutions. If you don't think price is too relevant I will highly recommend this one!


Excellent Four Season Softshell
I purchased the Sigma AR jacket to compare with the Patagonia Core Skin jacket. The Sigma uses Gore-Tex fabrics, while the Core Skin uses Polartec. The main differences are that the Patagonia jacket has more coverage in the back and also fits more closely. It has gusseted sleeves, and is a bit more stretchy than the Arc'teryx jacket, making it easier to add fleece or other thick layers underneath. (You can do the same with the Sigma; it is just a tighter fit.) On the other hand, the Sigma is a true year-round jacket, while the Patagonia Core Skin would be overkill in anything but cold or almost cold conditions. Both jackets breathe well. The Sigma has pit zips, and the Core Skin vents through the hand pockets. In my experience, the Core Skin breaths so well that you don't really need the vents in most circumstances. Bottom line: two great products, with slightly different approaches to cold-weather protection.


great all purpose jacket
I've worn the Sigma AR everyday since I bought it. It has been incredible, shedding rain, snow, and wind easily. Haven't been able to test it actively (backpacking, cross country skiing, etc.) yet, but I'm looking forward to. Don't expect an overly warm jacket; buy something else if that's what you need. The fit, as Arc'teryx products are designed to be, is snug. If you want to do a lot of layering underneath buy a size larger than normal. Oh, did I mention it looks great as well?


Sigma Ar jacket
Superb materials, construction and design except for one crucial detail. There is no flap covering the pit zips leaving the stiff zipper to chafe on your skin and stick into your armpits. No other manufacturer does this; for the price this is unacceptable. I returned it and bought Mtn. Hardware Tech.


DA BOMB!... without a hood
Hello "Gearheads"! Arc'Teryx does it again... so what else is new eh? The Sigma AR has Gore Windstopper and pit zips. The Sigma will work on the slopes, X-C in the woods, open the zips and your bike ride won't be a sweatfest! I bought the Salsa from backcountry.com, and I've gotten a lot of compliments already. I also own the Gamma MX, but the Sigma AR gets the nod in nasty, windy conditions. I'm looking forward 2 my bike rides when the snow melts! BUY IT!
