you read it exactly right. Keeps your sweat in, while letting all the outside moisture in, its also very wind proof, so there is no chance of cooling down.
Hmm. Seems as if the solution is to wear it inside out

ThanksSo N80P-X is a fabric and Gore Pro is a membrane. Both are important factors in breathability (and durability). The Sabre uses both. Any Goretex membrane will usually be more breathable than proprietary membranes like Helly Tech - they're mainly PU, which traditionally has either been less breathable or less waterproof, depending on how thick the PU layer is (they're getting better every year though - and PU membranes like Dermizax are getting closer). eVent is the most breathable membrane material since it's ePTFE, which is super thin. The problem with ePTFE is that it's oliophilic and oils eat away at the membrane. If you go with an eVent jacket, you should wash the jacket on a regular basis (every few wears) to get the same mileage you would out of other waterproofing options. If you run really hot, it's worth it.
Gore takes the best of those two technologies and uses ePTFE and PU in their membranes so that they're a happy balance of oliophobic and breathability. Pro is a different, more breathable, more waterproof upgrade compared to standard Goretex. Either way, these can get washed once or twice a year for weekend warriors and hold up for many years.
Fabric knits/weave patterns also influence how breathable a jacket is - I ski in a jacket that's a 75D X 160D polyester dobby. Incredibly durable for a <$150 jacket and cuts wind insanely well, but the flip side of that is that it doesn't breathe. Nylon is a lot stronger than polyester, so manufacturers can get away with a lower denier on a nylon jacket than polyester (basically more space between threads), which improves breatheability. Likewise, knits are a way looser fabrication than weaves and breathe much better as well, but they're much less durable and more prone to pilling. Big problem since the outer fabric & inner lining need to protect the membranes from dirt & oil. Goretex introduced their C-Knit fabrication where the outer fabric is woven and the inner is knit and it all gets laminated together with the membrane. Knits are also cheaper to produce at the mills.
Regardless of which membrane/fabrication you go with, none of the changes in weave or waterproof materials have as big of an impact as mechanical venting. Giant pit zips that extend down your side > fancy fabrics if you're looking to beat the heat.
@pack21 - weird, yeah, most sites make no mention of Pro, but if you expand the "Full Product Features" on the Arcteryx page, it lists it as the membrane. I'd bet the spot I'm referencing is the mistake since it's the only mention of Pro. I think the Sabre might be a tad overpriced. Looking at something like the Sabre LT (uses 3L C-knit with the knit backing), it's super similar construction to the Armada Lifted. Not necessarily egregious, especially without being able to see the seamwork, but an MSRP starting with $5XX seems more in line.
It won't be hard to beat Hyvent. With the exception of Hyvent Alpha, it's a coating instead of a membrane and has a breathability rating of ~12,000 g/m2.
In terms of fit, the measurements on the Arcteryx size guide are for body measurement - your waist, inseam, etc, and doesn't vary between relaxed/regular/next to skin fit. Those fit types either have hard specs (relaxed is always 3in larger than regular) or there's a more general guideline in fit review (relaxed fit should fit over the Thorium AR puffy). They consider what the end use of the garment is, where the person will be, how they'll be layering, etc.
The Beta AR is a regular fit, and it's a really general use jacket that's not designed for any particular sport, but supposed to be okay enough to use across hiking, mountaineering, a little rock & ice climbing, skiing, etc. That customer needs enough room to layer, but not so much where they need to be worried about getting their jacket caught in their belay device. A large sounds like it might be perfect for relaxed fit but that you might want to size up for regular fit.
If you're digging the Gore Pro construction, the Armada Balfour, Norrona Lofoten, Patagonia PowSlayer, & NF Freethinker might be worth a look.
If it surpasses Polartec NeoShell for breathability and the fit is correct for me, i.e., no armpit wedgies, no uncomfortable neckline and the collar doesn't wanna dislocate my mandible fully zipped hood up over the helmet, I'll buy one, and I already have an Arc'teryx Sidewinder Shell made of the lattest generation Gore-tex Pro fabric. Prior gen gore-tex pro was not even close to being as breathable as the updated current gen fabric which is still behind NeoShell.Interesting, but - big problem - they don't use pitzips because it's so breathable, in my point of view this is wrong,

If the menbrana futurelight really confirms to be very good, the second generation of jackets will certainly have pitzips, but as i said at the moment, without pitzips is a step back that i doubt would eat.
Of course, as i said it seems interesting, although it seems to me that for people who easily overheat the lack of pitzips seems to me to be a problem.If it surpasses Polartec NeoShell for breathability and the fit is correct for me, i.e., no armpit wedgies, no uncomfortable neckline and the collar doesn't wanna dislocate my mandible fully zipped hood up over the helmet, I'll buy one, and I already have an Arc'teryx Sidewinder Shell made of the lattest generation Gore-tex Pro fabric.

Fortunately,Spending many days in duck blinds I learned that warmth, breathability, and waterproofness are usually independent of each other even in higher tier gear. You can stay very dry from the rain but get soaked from sweat, stay very warm until the rain soaks through whatever membrane-of-the-day is in the coat, or be cool until you're wet and cold.

Interesting, but seems to start with a big problem, at 2:20 of the video she says they don't use pitzips because it's so breathable, in my point of view this is wrong, because NF is mixing the concept of breathability with temperature regulation, the first has to do with elimination of condensation caused by sweat, the other with temperature regulation we want at certainly moment.
Not having pitzips we can no longer regulate the temperature down. The concept of not needing pitzips can be accepted in the case of sofshell, in which a person wears a highly breathable jacket and a very fresh baselayer for the whole day, as he knows that heat will be all day on. Now for a hardshell, not having pitzips is one step behind.
If in morning we take a hardshell it's because the weather is bad, not so good or it may have high variation during the day, and without pitzips in the hottest periods of the day, i willn't be able to reduce the temperature unless i open the front zip, which obviously isn't a solution in this price range, in the case of the pitzips under the arms, which for me is the best location, allows to raise the temperature, if there is cold wind at lift chairs level, closing the arms, soon afterwards we refresh during the descent with the open arms and movements .
I honestly didn't understand the idea of NF. If the menbrana futurelight really confirms to be very good, the second generation of jackets will certainly have pitzips, but as i said at the moment, without pitzips is a step back that i doubt would eat.
