  • Laminated waist hem and drawcord help seal out drafts
  • Jacket features no-lift, gusseted underarms so it doesn’t ride up when you reach for a handhold or tool placement
  • Alpine pockets can be accessed while wearing your harness
  • Arc’teryx designed its athletic-fit garments to have a close, articulated fit that layers well over a base layer but also fits under a hardshell jacket

Looks good, heavy but not wind proof

  • Familiarity:I've put it through the wringer
  • Fit:True to size

I had the Gamma AR Softshell for over 4 years so it must be the older version. I love that it looks good with working shirt so I use it mainly to work and sometimes business trip. It is thick and a little heavy for outdoor hiking use. It shed rain and I always take care during washing to make sure material remain waterproof. I had used it once in Chicago and does not block wind very well. You have to layer it during old winter or heavy rain/snow. Great for California weather but for not windy and cold place. Very durable so I will be using it for years to come.

Good looking softshell, still uncertain about the pocket positioning.

While not maybe not the best for sticking your hands in, the pocket positioning is great if you have a pack or harness on. Also you may be surprised at how comfortable it is carrying stuff in the pockets when they are higher on the torso as opposed to banging against your hips while you walk.

Very sleek

    Very cool softshell, I use it layered under my waterproof jacket when snowboarding. Provides some water resistance, so it could be taken by itself on a spring day. Jacket looks really good.

    I find the pocket positioning somewhat awkward.

    Arc"Teryx Gamma AR Softshell Jacket

    • Familiarity:I've used it several times

    This jacket is incredible!! Very light weight yet it provides a great amount of warmth. I live in Virginia and the temps do not get too cold but we get 30 degree weather. With a base layer and this jacket I stay plenty warm. I have worn it in a light drizzle and was amazed at how well it repelled the rain. I would definitely recommend this jacket. Arc'Teryx makes the best stuff and this jacket is no exception.

    For tall guys

      Years ago, I always passed on anything from Arc'teryx due to the high prices. I usually went with Mountain Hardwear. But after buying my first Arc'teryx and experiencing the fit and quality. I was a convert.

      Several pieces (and dollars) later, it's the main brand that I buy. If you are tall and slim Arc'teryx is made for you. I am 6'6" and 205 lbs. The arms are always long enough and the fit looks tailored.

      The Gamma MX runs just slightly smaller due to it's athletic cut but fits perfect. I got the "Nightshade" and it is actually much darker than it looks in photos. This was an added plus.

      The only problem with this brand is that when you get a piece you want to wear it everywhere you go.

      My son is 6'4" (possibly taller now, as I haven't seen him all summer). He weighs appx 170 lbs, as he hasn't grown into his frame being a late bloomer. I am curious as to what size you purchased at your size - he wears a large in North Face, but they seem a tad short in the torso. He tried on a Hyllus Hoody in XL that was perfect through the shoulders, long enough in the sleeves and torso, but seemed a bit baggy through the body. Would appreciate your feedback - even if you're a good 35 lbs and up to 2" taller - it gives me a gauge.

      Are you referring to the Large or XL size?

      I'm 6'6, 215, long arms but not esp. long torso, chest 44 waist 32, I like snug tailored fit. E.g. I have a TNF Plasma jacket in Large, love it, arms just a tad short when I'm riding a bike. I would rather get Large if the arms are long enough and chest not too tight.

      great gift, great jacket

        Got this for christmas, have been wearing it quite often since then. Great jacket for the cold, windy, and often wet San Francisco winter days. Took a little getting use to the pockets, jacket is designed with the thought of you wearing a pack so they are easily accesible without having to take the pack off. After a few weeks the pockets being different isn't noticeable.

        Overall, a great jacket. Can't wait to add more to my collection.

        Rewrote my review after a little more use.

          I have an older Polartec version of this jacket and it's been one of my absolute favorites. The Gamma AR has been comfortable and warm from the Cascades (with adequate layering) to hanging out in downtown Seattle or Portland. Sheds light rain, cuts the wind, and breaths well during more active pursuits. No complaints whatsoever.
          I just picked up the new version with Fortius 3.0 and wrote a review that wasn't entirely fair. So, I'm rewriting it a bit. This new jacket is almost identical in design to the old one. The fabric is stretchy, hangs a little lower in the front than the old style (which is nice), lightweight, good pocket placement, nice range of motion, and that great Arc’teryx style. When the temperature falls much below 30 degrees, the new Fortius face fabric expects you to be active to provide real warmth as a standalone shell. The original jacket, with Polartec, immediately felt warmer. This is still a great jacket. After hiking or climbing with it, it makes a great mid layer under a shell. So far, I like the Polartec version a little better but I would still buy this one again. Oh, I haven't had any issues loosing things out of my pockets. Arc’teryx’s brilliant designers put zippers on mine to keep them closed. I know! Innovative, yeah? New Fortius 3.0 AND zippers on the pockets! 5'8, 170 pounds, size medium, fits perfectly with enough room to layer underneath.

          Heavy weight material, lousy pockets

            this is a great jacket if you don't mind wearing something that feels like a heavy weight plastic bag with a little "fuzz" on the inside. Just heavy, cold and quite "tight".... I picked mine up a few months ago and even though I generally like Arcteryx products, this one is a dud.
            The jacket is also really great if you like loosing you keys, or for that matter anything which will inevitably fall from the poorly designed front pockets.
            Think I put mine on Ebay....

            What is the difference in the versions of the Fortius fabrics? Is it just how thick the fleece backing is?

            Hello, I currently have a Venta AR that...


            I currently have a Venta AR that I use most of the time. It's really my go to soft shell. I was wondering how the new Fortius 3.0 Gamma AR stacked up. In the fall/winter, I throw on a Alpha SV or Theta SV as my shell with my Venta AR as my midlayer. It does get pretty warm depening on my activity. My question is....Am I losing a alot of warmth by going from the Venta AR to the Gamma AR? I understand that the Venta is Windstopper and stops just about anything, but as a midlayer I find it warm. Will the Gamma AR provide enough water resistance as a stand alone soft shell? I know it's not Gore-Tex Proshell, but my Venta AR does a pretty darn good job at repelling the water on those rainy days.


            Best Answer

            You will have a bit less weather protection than in a Venta, but this Gamma AR will be much better as a layer, because it breathes better than the Venta. Despite it not having a laminate, the fabric still has really good weather resistance, not totally water or wind "proof", but that is when your Theta SV kicks in.
