starting up elephants head gully in smugglers notch.... weather got nasty and i wound up throwing the Alpha SV over the top.
thoughts on this combined with atom lt? Atom LT too warm for high output...kind of at a toss up right now trying to revamp my layers. I have an alpha SV for shell and generally wear a rho LTW base layer.
ive got this, a patagonia R1, an atom LT, and an alpha SV as my main ice stuff. been rocking some subset of those all winter, down to 0 degree days at willoughby and frankenstein, and its been great.
this fits nicely in the highly-breathable, decently windproof niche, when its gusting a little but the SV would be overkill. if stuff gets really nasty, i'll just bust the SV out over the atom LT and this guy.
sometimes i wish i'd gone for the Venta or Gamma, but i think this is a lot more breathable than either of those (hard to say since ive only climbed one day in the Venta).
i have the same items, except i also have the venta mx and a patagonia nano puff, im currently trying to re vamp my system, but having a hard time trying to put the right stuff together. I think i am going to go with a smartwool micro weight wool t shirt, and then the r1 for my base layer, followed up by the acto. Im thinking for high output even down to about 15F that should be a good set up. After that im at a cross roads. Do i keep the venta mx, which layers fairly nicely over the acto and the r1, or return it and add the atom lt, or the nanopuff for my next layer. I was thinking of getting an atom SV for rest stops/belay jacket in moderate temps. let me know what you think. The ACTO fits fairly snug on me, so layering anything besides an r1 under it is probably not going to work too well. Anyone please chime in for some suggestions...?
i havent used the nanopuff myself but ive heard good things. i personally get super warm super fast, so im often just wearing a merino baselayer + the R1 on approaches, add the acto mx or atom lt while climbing, and carry a nice warm belay parka (just settled on the Rab Neutrino) for stops.
i find the merino layer + R1 + Acto/Atom LT will keep me warm in just about any weather if im moving (unless its super windy, in which case i put on the alpha SV).
if i were you, i'd probably keep the venta mx, and add a heftier belay jacket (the atom SV, Rab neutrino, or patagonia DAS parka, depending on your down/synth preferences) for stops. i wouldn't use the atom lt or nanopuff as a belay jacket unless it was pretty warm out.
which is warmer, the gamma mx or the acto mx? Also which one will breathe the best? I am looking to put a hardshell over either.
Though I have not bought the Acto MX, I am going to for christmas. I have done a tone a research on the Acto and Gamma. I was trying to decide between the two as well. I just totally revamped my system. I use to use Synthetic jacket like the montbell thermawrap and arc atom lt and would sweat WAY too much. Now...
Base Layer: Ltw meriono wool like Rho Ltw
Midweight: Acto MX
Outershell: Just got the Alpha FL to specifically go with Acto- I have the Alpha LT as well and I am going to most likely sell it. 3 Layer Gor is way tooo much. Excited to try this piece. The two layer will hopefully be breathable enough. If not I am done with Gor.
Pants: Gamma Lt - No gaitors, using bungee cords w/ grommets
Synthetic Belay Jacket: Dually, Kappa, Patagonia DAS type of jacket
Synthetic Pants: Atom Lt
Personally I am going with the acto. I have used the gamma a couple times and like it for trips to Ouray but not for alpine climbing, mountaineering it seems like acto is going to be a game changer for me personally.
Sorry I dont have first hand experience in the field. I have tried on the acto and it is a top quality jacket. Ill let you know in a couple months how it all plays out.
Any similarities with this piece and the Patagonia R1?
There are some similarities - the key difference being the Acto MX offers much more weather protection than the R1. The Acto features a stretch woven nylon face that offers a great level of wind and water protection in addition to some stretchy goodness. This is my go-to touring jacket, check out the attached pic of the Acto MX in action!
Thanks. Im looking into revamping my system. Any thoughts/opinions of a baselayer (synthetic or wool depending on weather), Acto MX, Alpha FL Hardshell and belay jacket (for rest stops, Im thinking Atom SV) a good system? Ill be doing high output activities such as mountaineering, alpine climbing and ice climbing on 14ers. Hoping to do some winter ascents as well.
Does anyone know how warm the Acto is compared to a piece like the R1?
Josh - that sounds like a great system for the activities you mentioned. I'd also recommend looking at the Alpha LT hardshell. While it's not as breathable as the Alpha FL it does have pit zips and a more durable face fabric. The Alpha LT also features harness Hemlocks that help prevent the hem of the jacket from creeping up past your climbing harness.
The acto mx is that good that you can ski in powder like that? It looks very fleece like, which just absorbs water, guess its not though.

I've used a variety of softshell jackets over the years and I've finally found my perfect one. This jacket certainly would not be perfect for everyone, but here is what I like about it... extremely breathable, warm for the weight, long length, close-fit yet still allows room for layers underneath.
Beware that this jacket does not block wind, like say a WINDSTOPPER softshell, but it breathes about a billion times better. It works best when you are working hard in cold conditions, like skinning or snowshoeing.

- Familiarity: I've used it several times
Faced with the choice of a warmer Gamma MX hoody or the Acto MX hoody, I favored the Acto due to the breathability and greater versatility.
Having worn this in zero degree Celsius, it's comfortable over just a thin base layer. The wind-cutting ability is great, with just enough air flow to keep high-output activity perspiration vented but without getting a chill from big gusts.
The trim fit permits just enough room to wear a base layer and thin puff or fleece underneath; but the cut is excellent as the lack of bulk avoids the jacket getting in the way during hiking or climbing.
Hood adjustments are great with or without a helmet. The helmet-sized hood seems large at times, but the draw-cords on front, and the volume-adjuster on the back side assist in minimizing volume and keeping it snug when necessary.
The Acto has now become my go-to hoody for minimalist layers both for the autumn and winter season.
I have the Polartec Powershield Gamma MX. I actually love it and it is worn most often on a daily use. Though, for running in the cold, I wanted to try either the Acto MX or the new Gamma MX with the Fortius material. Can anybody compare the two and which one would be better for cold weather running, hiking, and layering. I think they are really similar and at the price points its almost negligible. As I already own a Gamma MX of different material which one would be best?
I'd suggest going for the Acto as a cold weather runner and a layer. While the new Gamma MX is sweet, you might as well broaden your quiver a bit.
For running, I'd say the Acto for sure. It breathes well but still resists weather. The Gamma MX might be more resistant, but rare is the runner who will be out in bad weather for hours. Breathability and comfort are more important. Although the Acto is less form-fitting than the Gamma MX, less of a pliable material, it nevertheless moves incredibly well with your body. I feel very comfortable with it while running (or running errands), and I imagine skiers and snowshoers would agree. I think Arc'teryx has done a superb job of tailoring this jacket for active use. It's a great jacket!
In the last month I've ski toured, mountain biked, and camped in this jacket. Breathes better than any layering piece I've ever owned and still blocks wind and moisture. I was weary of the chest pockets at first, but they're much more accessible than traditional side pockets near the hip. At 6'2" 185 lbs, the large is perfect.
This is my new favorite jacket for when it's not pouring. The most versatile piece I own, can wear it in everything from a light rain to windy bluebird. Breaths great on the uphills, and fits nicely under the shell for the ride down.
I have come to love this jacket, though I don't think it's quite perfect. I'd give it 5 of 5 stars for the fabric, but only 4 of 5 stars overall. I'd give it 4.5 stars if that was an option. I personally think the cuffs, hem, and hood need a little work. I wrote a full review with pictures at
very close fit and impecable finish. the DWR is awesome and it works perfectly under my Alpha FL. gives nice layer of insulation and can pull double duty as an outer layer in dry conditions. perfect cross between jacket and hoody
Great jacket. I was a little weary of getting this at first, and honestly figured I would end up returning it, but in the end I will definitely be holding onto this. Since getting it, I honestly have not taken it off. The lining is buttery soft and extremely comfortable. The outer fabric is pretty stellar as well... has a bit of stretch to it much like a Gamma MX, but has less of a soft shell type feel... almost like a sturdy cotton texture. It poured today, and the DWR repelled the rain without any problem. The fit is a little closer than the fit of the Gamma MX, but not too close. The outer fabric seems to be pretty bomber as well... it should be able to take abrasions pretty well, probably even better than the Fortius material. Stitching is really nicely done, zippers are great, and the lining around the collar is REALLY soft and nice. The hood is perfect... great adjustability, and could accomodate a helmet easily, yet I was able to cinch it down perfectly on my head today almost like a I was wearing a ball cap. Perfect construction on the hood, very pleased. Wind resistance... not too bad really, but it is not windproof, nor does it claim to be. It breathes very well, without ever becoming clammy at all. Only two downfalls I noticed first hand... no side pockets. Yes, I know it's because it is for climbing and to allow access with a pack on, and yes, in that aspect the front pockets are money. But when not on the trail and out around town or around base camp it would be great to have two simple pockets to throw my hands in. Just sayin'... and especially at a 300 dollar price tag. And that brings me to the second downfall... the price is high. Yes, I love this piece, and yes, I will keep it... but is it worth 300? That's really something you will have to decide... for me, I can see myself literally wearing this almost everyday, and so while it hurts, I can cough it up. With that said though, I can honestly say it's priced pretty high for what it is, even though the fabric is top notch and the garment as a whole is amazing... it's still almost impossible to justify the 300 dollar price tag. The other downfall is the back... it seems to drop quite a bit lower than other Arc'teryx pieces I have. It's not a big deal, but in the future maybe not so long would be a bit better.
Overall, great product, though a little high in price for what you get... but then again, that's Arc'teryx. Top notch gear, with an equally top notch price. If you can swallow the price factor, get this... I can tell you you will love it and it will quickly become your go to everyday hoody/light jacket/etc. I honestly will wear this far more than my Gamma MX/LT or any other light everyday jacket, and as part of a layering system it's perfect. Great option for climbing in too as a result of the bomber outer fabric and nice stretch.
I have tried on this jacket and love it. The question I have for you is, i own a gamma MX and a Gamma Lt. I want this to be a good backcountry ski jacket (uphill) and also for trail running in temps in the teens to mid 30s. Will this breathe similar/better or worse than Gamma Lt? I want some thing with a bit more warmth and next to skin comfort than the gamma Lt-thats why im looking at the Acto. What do you think? Thanks.
I'd say the Acto is exactly what you're looking for to fit this performance bill. It breathes like crazy while still being very weather resistant. The grid fleece does give it a bit softer feel than a Gamma LT on your skin while being less insulating than a Gamma MX. Pair it up with the Phase SL baselayer for a super efficient kit for high output in cold weather.
How does this compare with the venta SV? Is it warmer? Is it waterproof?
To answer Tester's question which appears here, the Acto is exactly the opposite of the Venta. The Venta is made of Windstopper and the Acto is described by Arc'teryx as "highly air permeable." It's designed to keep you from overheating during high-output activity so it allows air to flow both ways. It does have some insulating value, but it's meant to be used on the move.
Hi, I'm 5'8 and 152 with 38"-39" chest,
should I get a S or M? Is this jacket
The Acto is designed to be worn with a baselayer and very thin insulator, at most, and it's cut to be a close fitting jacket. It will block about 80% of wind, so if it's really blasting on a ridgeline, the Alpha or Beta FL (goretex active shell) is the ideal layer. Meant to be worn while moving, so brethability with some weather protection, as opposed to lots of insulation, are key elements.I'd guess a small would fit you most correctly according to the design.
I hear arc-teryx runs a bit large.
Im 5'10" and 130. Will be the small be too baggy for me? I like a relatively snug fit.
Small should be great. Arc runs a bit large, but it's very fitted, so you should be fine.
Arc'teryx does not run large, and especially in this jacket. If anything it's a closer fit than other brands. A small will fit you well.
I'm 5-10 and 135-140, and I think it fits great. Trimmer than the Epsilon. The fit is more along the lines of the Tau or Atom LT. Arms aren't super-long, either, as they are with some garments (I think they're sized correctly as they are slightly long for my slightly short arms). The fabric has a great hand and is extremely flexible.
Arc has 4 different kind of fits, trim, athletic, relaxed and expedition with Trim being the smallest one. Atom LT and gamma MX are athletic and Hyllus is relaxed. Although I do feel that atom lt fits closer than gamma mx/ar
is the brimstone a true yellow or more of a green like their lichen color?
It's a greenish yellow. I don't think I've seen the Lichen in person but I think it might be close to it, based on what I remember from online photos (for what that's worth). I have the Brimstone and really like it. I think Arc does great with colors, especially with ones like this that aren't obviously a particular color. To elaborate, I'd say that it first strikes me as yellow but it quickly becomes obvious that it's not the yellow of an old-fashioned rain slicker, but a subtle greenish yellow.
Let me revise what I wrote, since I can't figure out how to edit it. The color is similar to the color of reflective clothing and road signs of the last 20 years or so, although slightly more yellow. The more light that's on the jacket, the more yellow (and bright) it looks. The trim is a subtle forest green, so that gives you the idea that it has a foot, or at least a toe or two, in the green family. But it is a bright yellow jacket; there's no denying that.
How does this compare with, say, the Epsilon or Tau?
The Arc'teryx Acto is closer in feel to the Epsilon, but it's an amped up version. Not as much insulation value, but better breathability, durability and a closer, layer fit.
I had the chance to try this jacket on recently and I found it to be an amazing piece of equipment that I can't live without. You can rock it on it's own or use it for layering. It is super versatile and extremely technical. Perfect for any outdoor enthusiast. The liner is a fleece grid that can let heat out while wearing it alone or keep heat in if you are layering. Use this for anything you do in the snow. Not to mention it has a lifetime warranty. Awesome!
