Outerwear 201: Marketing Wars, New Technologies, Paradigm Shifts

[Editor’s Note: This is a follow up to our Outerwear 101 piece. If you haven’t read the 101 article yet, you might want to start there. It’s an outstanding overview of outerwear technology and applications, and a good read for anyone who uses technical outerwear.]

The Old Paradigm

Outerwear technology isn’t the sexiest topic in the ski industry—it’s more fun to compare the specs on your new skis with your buddies than the specs of your new jacket.

But that may not be true for long. The outerwear industry is undergoing its first serious paradigm shift since the 1970s, when Gore-Tex founder, Bob Gore, invented waterproof / breathable fabrics (“WPB”).

Over the past 40 years, we saw skis get shorter, then shaped, then fat, then rockered, then tapered. Ski boots went plastic, lost their laces, lost their buckles, re-gained their buckles, got taller, got shorter, then got tall-ish again.

Outerwear pretty much stayed the same.

Sure, there have been a few notable advances in outerwear technology in the past 45 years—primarily 3L fabrics, waterproof zippers, and seam welding—but none that changed the game as radically as, for example, fat skis have.

Today, however, outerwear technology is finally getting some attention, thanks to the invention of air permeable fabrics (“air perms”). These WPBs allow a very small amount of air to flow through them, which in theory greatly increases their breathability. These fabrics are still waterproof and breathable, but without being 100% windproof—which is a very big deal. Why?

Because air permeable fabrics challenge the main pillar on which the entire outerwear world is currently built, the “Waterproof Above All Else” pillar.

Oh, and not only do air permeable fabrics challenge the pillars that waterproof / breathable fabrics are built on, their existence is threatening to tip the balance of power in the outerwear world. Why?

Because Gore-Tex, the undisputed king in the WPB world, has yet to market a fabric as being air permeable.

This is because the idea of air permeability is in direct conflict with the main pillar of Gore’s philosophy: the “Waterproof Above All Else” pillar.

Consumers have been conditioned for years to think in this “waterproof above all else” mindset, in large part, because of the marketing of the reigning king of the WPB world. Gore-Tex has become such a household name that it has achieved the hallowed commercial status of a proprietary eponym, like Kleenex or Velcro.

Many people believe that they need Gore-Tex to stay dry—that only Gore-Tex can keep them dry—and that is not an easy belief to market against.

The Shift

But companies like Polartec and eVent are embracing these new air permeable fabrics and attempting to market them for what they really are—a legitimate WPB contender that is not 100% windproof.

For many consumers, “waterproof” and “windproof” are part of a hierarchical system: Waterproof > Windproof > Wind-resistant. And the common assumption is that if a fabric is waterproof, then it is also windproof (and certainly wind-resistant).

But air permeable fabrics disrupt this hierarchy. These new fabrics are waterproof but they are not technically windproof, even though they are effectively windproof.

There is no current label for “Effectively-Windproof” in the standard consumer system of thought.

It will be interesting to see how the public perception of Gore-Tex and the “waterproof above all else” pillar change in the next few years. Although marketing a waterproof fabric that is also air permeable is no easy task, air permeable fabrics are a serious market share contender in the high-end waterproof / breathable realm.

But the real aim of this article is to provide an overview air permeable technology. It is in no way a comprehensive audit of the technology, but I have tried to touch on each of its important features. Air permeable fabrics are relatively new, and where the technology is today may vary vastly from where it ends up in the next few years. It will definitely be fun to watch where it goes. And who knows, maybe we’ll even see an uptick in chair lift conversations that start off, “Sick jacket! What’s the air pressure drop across the membrane?”

Dry Is Dry: The Air Permeable Advantage

Air permeable fabrics (“air perms”) are a complete paradigm shift in the waterproof / breathable (WPB) world.

In the recent past, Gore’s 100% waterproof guarantee was a great reflection of the state of the industry: consumers were first and foremost concerned with staying dry. But the world is changing, and consumers are starting to realize, to borrow some of Polartec’s marketing verbiage, that Dry is Dry; there is no such thing as being more dry. There is very little advantage in a 20,000mm waterproof membrane compared to a 10,000mm rated membrane, which is what many air perms claim to be.

Consider:

• a 10,000mm hydrostatic water column rating equates to about 14psi

• the hardest wind-driven rain only exerts about 2psi

Conclusion:

• you don’t need a 20,000mm membrane to stay dry.

Yes, outerwear is subjected to higher pressures than wind driven rain in the field (falling in wet snow, straps and hip belts on heavy packs, etc.) but these are still unlikely to exceed 14psi.

So air perms are waterproof. They’ll keep you dry. Their advantage is that they purport to offer enhanced breathability.

Breathability: WPB vs. Air Perms

Traditional WPBs are breathable in that they transmit water vapor through the membrane via a single mechanism: solid-state diffusion. (More details on this below, but for a more thorough explanation, I’d recommend hopping over to the Outerwear 101 article.)

Air perms, on the other hand, breathe via two mechanisms: solid-state diffusion and, to a much larger extent (and as the name implies) by moving air directly through the membrane. This is a convective mechanism.

And that is the primary reason for the “enhanced” breathability of air perms: in addition to the diffusive mechanism, air perms also have a convective mechanism that contributes to their breathability.

The second reason, as we’ll see below, is that there are fewer barriers to inhibit the existing diffusion mechanism in an air perm membrane than in a traditional WPB membrane.

  1. I have been making outerwear for years from both Gortex, and Polartec Powershield (and most recently Polartec Neoshell, which is a killer breathable) and I REALLY enjoyed your in-depth article. You know your stuff! We occasionally sell excess fabric from the Discovery Trekking website, and I can tell you that when we get these fabrics in, they get scooped up pretty fast. Even though some of the Powershield technologies are not brand new, I am still wearing pants and jackets I made 8-10 years ago and have never had an issues. But I agree that they are getting better and better. Thanks for the great article.

  2. I’ve been using the Patagonia Knifeblade pullover, with Powershield Pro, which as I understand it is a more breathable version of Neoshell. Very impressed. A jacket (pull-over actually) that is functionally weatherproof for ski touring, but unlike every other shell I’ve used – doesn’t act like a vapor barrier when working hard. I’m a believer, and am definitely going to add pants and a puffy (Polartech alpha?) using this technology for next winter.

    • Hey Stewart,

      The knifeblade is a killer jacket! I was bummed I didn’t buy one while I had the chance…

      I am currently testing a Polartec Alpha piece and we’ll have the review up in a few months. So far the insulation has been exceptional. I think the main issue this coming fall will be limited styles because it is such a new technology.

  3. very nice article!
    What can you tell me about these mountain shirts from Buffalo??
    It uses pertex and “aquatherm pile lining”
    Some people swear by it but I’m sceptical..

    • Hey Kevin,

      I don’t have any person experience with these jackets, but from looking at the site they appear to be a fleece lined windshell (2L construction) that uses Pertex for the face fabric. This means that there is no WPB laminate and the jacket will not protect you well in harsh conditions. It looks more like something that would compete against softshells rather than hardshells. Without taking a look in person though its hard to say!

      Sam

  4. Great article! I heard that Gore has been working on a new insulation that has a twofold purpose. In cold conditions the insulating material expands creating more loft, thus retaining more body heat. When conditions are warm the material contracts allowing more body heat to escape. It was designed for the
    military but has obvious application for any outdoor enthusiast. Keep up the good work!

  5. Sam
    Very useful write-up.

    Be curious to get your thoughts on Polartec PowerShield Pro vs Neoshell? How does Polartec Alpha fit in this paradigm? Guessing it would fit as a mid-layer.

    • Hey Michael,

      I am currently testing both a PowerShield Pro piece and an Alpha piece. So far I can say the PowerShield Pro breathes very, very well. Definitely better than Neoshell. It is also a softer/quieter fabric with a bit of stretch so it is very comfortable. You do sacrifice a decent amount of protection though when going to PowerShield Pro over Neoshell. The piece I have (Patagonia Knifeblade) does not have sealed seams (though they are all double top stitched) or waterproof zips. In shells, it tends to be a case of trade-offs and I don’t see this to be any different.

      As far as Alpha, there is a lot to be said about this insulator. The basic principle is that by using a very low density knit insulation, there is no need for a “down-proof” or similar fabric on the inside of the jacket. So Alpha jackets are lined in some sort of mesh which is much more breathable than the typical nylon fabrics used for puffy liners. I think the biggest challenge with this insulation is for manufacturers to figure out the best way to use it. I have the Marmot Alpha Pro jacket and it can’t really decide what type of jacket it wants to be…

      The bottom line though: Polartec is making waves in outdoor fabrics and insulators. They are doing it better and faster than anyone else.

      Thanks for your comments Michael,
      Sam

      • Would love to read your reviews of the Marmot Alpha pro and the Patagonia Knifeblade jacket. Do you know when you will have those available to read?

  6. Sam, if you are interested in seeing a sample of Neoshell and Powershield Pro, I do have some in my store and would be happy to slip a piece of each in the mail to you. It would be interesting as this particular style of neoshell and PS Pro look virtually identical to me. In this case, both styles are very lightweight and neither one has a fleece back. (Normally on Powershield, there is a fleecy inner side).
    Let me know. You can reach me via the Discovery Trekking website, or at info@discoverytrekking.com

  7. I just got in a few rolls of a different style of Powershield Pro. This one is midweight, and the backing is soft/thin tiny squares of fleece. I made my first jacket and LOVE it. Although I can’t compare exactly to my Neoshell jacket because the Neoshell I happen to have on hand is a much lighter fabric, they are both extremely breathable and comfy.

  8. I’m going to start posting here under this pen name. I work for a major player in the shell market, and I would like to be able to speak my mind without worry of saying anything “off-message”.

    TL:DR version: Goretex Pro for pants in the winter, Neoshell for jackets in the winter, unless you actively pursue skiing in the rain or are planning a trip to the local wind tunnel.

    My General conclusions from years of buying, selling and using outdoor gear:

    Event is magical for the first few days out. Then you stand around a campfire, sweat, spill food, sweat more and the magic levels of breathability start to fade. Then you wash the jacket and breathabilty returns. Repeat the cycle a few more times and you start noticing bubbles in the fabric. Soon thereafter large bubbles develop and either 1)the membrane starts separating from the face fabric or 2) the membrane separates from the backer fabric. Event CANNOT handle repeated exposure to sweat, deodorant, detergents, etc. There is a reason why the much hated PU layer in most Gore products. My Event jacket I had was warrantied twice and I gave up on the third time. I wanted to love Event, but a jacket should fall apart after 30-40 days of casual mountain usage. Also, another gripe about event is due to the wide pores it seems to pick up odors (food smells in particular) more readily than other membrane products. Also, to note- DriQ from Mountain Hardware is simply rebranded eVent membrane.

    Neoshell is a fantastic product for temps below 30°. It even does a pretty good job in above freezing temps if you’re careful with it. Where it falls short in my opinion is sustained rain on multi-day trips or anything involving pressure + wet. It does a good job in situations where you actively moving but I disagree with the contention that 10,000mm is the most waterproofing you need. I would never use Neoshell if I was carrying a heavy pack or lift-skiing frequently. It maybe a different story in the Rockies, but based on some of the Neoshell pants I have used in the Cascades/Coast range, I have found Neoshell to be inadequate for sitting/kneeling in truly wet conditions. A 180 pound man easily exceeds the amount of PSI that 10,000mm is representative of when kneeling with a pack on or sitting on a chair lift. Also, you can get quite a bit of pressure under shoulder straps on pack. This a bigger consideration in rain/sleet than true snow. Neoshell is pretty variable in terms of price, but you get what you pay for. I have seen some delam but not bad, most of the warranty issues with Neoshell come from manufacturing errors due to the difficulty that a seam taped stretch fabric present.

    The new Goretex Pro is basically a complete redesign of the old Pro fabric. They essentially share nothing in common, short of having ePTFE in them. The best way to think of New Pro is multiple layers of ePTFE that have cell structure somewhere between old proshell and event. New Pro does not have a PU oilophobic layer like previous versions of Goretex. It is air-permeable and from my field usage pretty damn windproof and breathable. The multiple layers of ePTFE provide a sacrificial layer to become contaminated without the issues that presents itself in eVent (fabric delam, leakage, decline in performance.) The 28,000mm Hydrostatic head is probably overkill for the Rockies in the winter or people sub-150lbs, but if you’re a 180lb bro with a 30lb pack or you ski/climb in an ultra wet environment (Cascades, Scotland, etc.) you will be glad for it. Nothing sucks more than having a wet ass from sitting on a chairlift. The main drawback with new Pro is that it is ungodly expensive. I think the entry point pricing from most companies on a pair of Pro pants or jacket is close to $500. Not something the average ski bum can afford. New Pro should be hitting stores within the next month or so.

    Goretex active is a good fabric, some durability issues. The first batch seemed to have the occasional delam issue but not to the degree eVent has. The main thing that is holding Active back is Gore themselves. There are pretty stringent requirements that make it hard to build a really 4 season worthy shell- pockets have to vent into the body of the shell (vs taped waterproof pockets on Pro) and there is a maximum weight (~13oz). This generally lends to lightweight designs, with small minimalist hoods, minimal room for serious layering and a general lack of features. It is a very breathable fabric but it is not Air Perm, and still features the PU layer. The other main drawback is how light the face fabrics typically are, 20d fabric will not hold up to a stout bushwack or thrutch through a chimney. Some companies are starting to address that with heavier face fabrics, but it will be at least another 6 months before we start seeing that product hit the market. Price entry point is ok for what you’re getting but not as good of a value as Neoshell. I think Arc’Teryx (surprisingly) may have the lowest cost of entry, but it is a really defeatured shell.

    All that to say my general philosophy for winter alpine climbing and skiing is that your pants should always be at least one step more burly than your jacket. For instance, my current systems are as follows:

    General alpine climbing in storm conditions:
    Neoshell Pants
    Gore Windstopper Jacket

    Touring in storm conditions:
    Goretex Pro bibs
    Goretex Active Jacket (Anorak style so I can be a mountain hipster/not suffer a space/weight penalty if the weather calms down and I want carry my shell.)

    Lift skiing in storm conditions:
    Goretex Pro bibs
    Polartec Neoshell Jacket (it’s a much heavier denier fabric than my Active shell jacket plus, I’m a gear whore. Deal with it.)

    • Thanks for your comments! I think you have brought up many good points, especially on the worthiness of NeoShell as a above freezing wet weather piece.

      Living in Colorado myself, we see typically dry and cold winters. The rest of the seasons can be wet – but typically severe afternoon thunderstorms are the most consistent form of precipitation. Combine that with my slight frame (~135lb) and general light and fast mentality in the mountains and I have seen no water penetration with NeoShell. However, I could see soak through happening with a heavy pack on, in a prolonged rain at the hipbelt/shoulders.

      I think the point about the durability of eVent is a very important point. Washing frequently with a VERY mild detergent, VERY mild water temperatures and hang-drying is essential. There just is not much protection to the ePTFE in the eVent laminate.

      I am extremely eager to try out New Pro Shell, hopefully we can get a test piece in the next few months. The idea of the “sacrificial” ePTFE is extremely interesting, especially in a product that Gore touts as its highest level of protection. We’ve had our eyes on testing this technology since SIA!

      Thanks again for your comments,
      Sam

      • Thanks Sam! I hope to be an active participant in these posts about outerwear. Don’t worry, I have plenty of opinions when it comes to insulation and softshells as well… and don’t get me started on packs and tents. :-)

        I think a real flaw with eVent is that you have to wash it frequently- most people struggle to change their oil on time, I doubt anyone really wants a shell they have to futz with every few trips. Every time you wash you should also evaluate if the DWR needs a refresh. Wetted out face fabric negates any fancy permeability or breathability plus in extended rain situations starts to invite leakage through the membrane. Unfortunately, no one has invented a one way membrane.

        This may sound crazy but I think the best applications for Neoshell are things that we haven’t seen anyone make yet- gloves, boots, wpb socks, etc. Where the PSI is low and need for breathabilty is quite high.

        I would love to see an Alpha insulated Neoshell jacket. Imagine how cool an insulated shell that you could actually move in would be? You could put it on in the morning and never have to mess with layers for the rest of the day.

  9. I’m confused about some of the opinions (not that they are wrong) but because, for example, Polartec makes a style called Powershield 02, or Neoshell, or windpro, or whatever…and its a group of fabrics with the same techncial qualities within the style, but MANY different weights. I have some Powershield 02 in my store, one roll is super lightweight and is identical in feel to the Neoshell, and other one is heavier. SO, when you are comparing finished garments that are Neoshell vs. Powershield 02, I know you can prefer one above the other, but unless you had the garment in various weights within each style, it would be difficult to make a generalization about one being better than another. They are all amazing, but after reading different opinions I would still have to make up my own identical garments from various weights of each style of fabric, then make my decision. I probably have 4-5 weights of powershield alone, in my shop.

    • I agree, it can be difficult to be black and white about Polartec products by comparison to Gore. I’m still not sure what exactly “Thermalpro” means, as I’ve seen it on everything from hiloft fluff fleeces from Mountain Hardwear all the way down to lightweight tech fleeces from various companies.

      Powershield is not a seam taped garment and the membrane does not have the same level of hydrostatic head that Neoshell has. There are also heavy fleece lined “Softshell” Neoshell fabrics, but they are very difficult to make a truly commercial product due to the difficulty of seam taping (stretch and material shift). Sure, 5-6 years ago companies were externally seam taping softshell when it was a really popular category but external seam taping looks like crap and fails overtime. It is generally acknowledged that powershield (particularly Powershield Pro) was Polartec’s stepping stone to a full waterproof membrane.

      Neoshell is better for true wet weather performance regardless of fabric weights than any variation of Powershield. Neoshell is a hardshell membrane with softshell like properties whereas Powershield is truly a softshell with hardshell aspirations. (No one would want Powershield in an extended rain storm. I’ve tried it and I wouldn’t wish the experience on anyone.)

      In general the only styles of Neoshell that major manufacturers have been able to build are similar in weight to Goretex Active or Performance shell with pretty traditional face fabrics and backers. I’m sure that the more interesting variants of Neoshell are awesome, but I don’t think they are suitable for building 5,000 jackets at a time.

      One of the biggest strengths of Gore is that they are pretty rigid on what each product is. You don’t have a whole lot of options beyond some variations of fabric weaves in the pinnacle fabric products from them. Goretex Pro fabric between one company and the next is going to be very similar. The main factors for purchase then become features, fit, finish and what logo it has. Which in someways isn’t a bad thing, I don’t think.

      (Although, as a side note: There is now quite a bit of variant in standard “Goretex” (now encompassing everything from Paclite to Denim Faced pants from companies such as Burton.) But I don’t think people at that level care as much about technical specs provided that a garment has the Triangular logo hanging off of it!)

  10. Sam, I’d ride the lifts with you! I love to talk about outerwear just as much as skis! Gear is gear, it all contributes to the things you can or can’t do, and the fun you have while doing it.

    One thing that was kind of brought up in the above comments, is that it’s not as simple as membrane X or Y, specific face fabrics have a huge effect on performance as well, as does garment construction.

    One way that you can illustrate the air-permeable but waterproof fabrics is with the Event-bottomed dry sacks.

    I wish more manufacturers would design a garment with differential fabrics, using each fabric in a location where it plays to its strengths. I.e. More durable, high hydrostatic head fabrics on the knees and shoulders, more breathable fabrics in other areas. For skiing especially this could be very beneficial, as OWNerd points out, kneeling, sitting and packstraps all exert high pressures. At the same time, hard, prolonged rain is rare in skiing.

    I think the problem is in marketing, it makes for a mixed message when you’re trying to sell it. That’s probably why companies like Patagonia keep trying and keep dropping the items.

    • I definitely agree with the fact that the industry is lacking good hybrid jacket at the moment. We are really interested to check out some of the new pieces from Arc’teryx that look to address this gap. However, like you said, it is certainly a marketing issue. Unfortunately, many people who buy these high performance jackets aren’t actually getting out and pushing the jackets to their limits. A large percentage of the market for 3L shells is upper/upper-middle class casual users, marketing a hybrid piece to that market is hard!

      Thanks for your comments!
      Sam

  11. Sam,
    I posted a reply to the Knifeblade review, talking about Nikwax Analogy. I see it’s still awaiting moderation. Can you move it here instead, this might be a more appropriate spot?
    I know it sounds like marketing promo, but I truly don’t have any connection to them ;-) Please check it out for yourself.

  12. Hey Sam,
    Thanks for the great article! I wanted to ask how Gore Windstopper fabric was constructed and how it compares to the others you discussed. I’ve had a Mountain Hardware Kepler jacket made with DryQ Elite for several years and have loved it for ski touring etc. Unfortunately, its getting a little ragged and I’m looking to replace it, possibly with a Black Diamond Convergent, which is made with Gore Windstopper Active. What are your thoughts about this fabric/jacket as an option for a skiing/ski touring jacket? Thanks!
    John

    • Hey John,

      Thanks for your response! I don’t have too much personal experience with Windstopper, however I can make a few comments.

      1) It will not offer as much protection as your old MH jacket. DryQ is a full hardshell and Windstopper is definitely not.
      2) Gore calls the fabric Windstopper active, and judging by the little info I can find on this laminate, it sounds like a standard soft-shell fabric. It is likely vey similar to Polartec PowerShield.
      3) If you are going to use the jacket mostly for ski touring somewhere dry (i.e., Colorado, Wyoming) then this should be fine. If you live somewhere a bit wetter (i.e., West coast) I would go with a full hardshell.

      I hope that answers your questions, without having worn anything with Gore Windstopper Active, it’s hard to say much more!

      -Sam

  13. Oi, just thought it prudent to give thanks for the effort. Hands down the most thorough 101 and 201 on breathables I’ve read on the www. At the end of the day, it still depends on your intended use. This really helped clean up my gritty mind and go buy. Cheers, Pete

  14. This is one of the best overviews of the technology for consumer consumption I’ve read. Well done. I do have a few comments and questions.

    Regarding this line: “With the seemingly obvious advantages of air perms, one logical question is, “Why are air perms just now hitting the consumer market?”” The short answer is, they’re not. eVent has been on the market for over a decade. It is true though that only since 2008 or so has it been more widely available (really part of this answer has to be Gore’s strong arm tactics regarding their contracts with manufacturers) but that’s still 6 years of reasonable availability which I guess is “new” compared to Gore, but not that “new” in reality.

    Regarding the windproof comments, I thought there was a standard for windproofness and that it wasn’t as simple as 0CFM? I can’t seem to find this info now. My understanding is that average eVent (and I assume the DryQ Elite from MHW) has a CFM of 0.1 and that “typical” Neoshell has a CFM of 0.5? I know there is some research on air permeability that states something to the effect that below a certain CFM the permeability can’t physically be felt as air movement. I also thought that that was the threshold for windproof? I can’t find that info right now either (about the CFM “feel” threshold);and I may have simply imagined that this threshold defined windproof vs air permeable?

    Either way, killer article, and great discussion in the comments.

    • Hey RPM,

      Thanks for the kind words!

      Yes, air perms have been around for longer than most consumers would believe. They have finally been picking up traction and market share in the past few years which is something I’m pumped on!

      As far as the CFM values, I think that you are right. There is a standard somewhere. A quick search around on ISO didn’t yield anything promising. I think the main issue with words like “windproof” and “waterproof” is that they have historical uses in less than precise context. Calling NeoShell windproof and then calling a Walmart uncoated nylon windbreaker windproof certainly waters down the value of the word.

      I do think your numbers sounds right though, I just can’t find the source at the moment.

      Thanks!
      Sam

  15. A truly glorious article – and the deepest and best explanation I have found anywhere.

    I would be overjoyed if you could shed some light on the final mystery membrane (from a European’s perspective anyway)… the Dermizax range from Toray. It is used by a number of high end European brands in their top lines – Bergans, KJUS, Killy, Peak Performance. I think Trew in the US also use it.

    The newest varietal, “Dermizax NX” is claiming 20,000mm, 30k-50k g/m2/24h (notwithstanding your caveats to breathability stats), whilst also being air permeable, and stretchy. Some impressive claims, but as far as I am aware, it is largely unknown in the US market.

    I have been spiralling into obsession looking for further information/confirmation/insight from someone who knows what they are talking about. You may be my last best hope!

    Thanks again for an amazing article, and amazing site.

    FWIW, Toray FAQ, says:
    “—What is the difference between ENTRANT*V and PTFE membrane?—
    APTFE membrane has micropores and is laminated to the fabric.
    ENTRANT*V is a polyurethane microporous coating.
    ENTRANT*V is a specially engineered fabric coating with extra high strength and durability. In the manufacturing process–from the fibers, to the weaving, and the dying, to the DWR coating process–ENTRANT*V is total quality controlled. The company’s advanced vertical manufacturing process ensures the consumer optimal performance and comfort in the ENTRANT*V line of activewear.
    Also, Toray’s ENTRANT*DERMIZAX* which has a polyurethane non-porous lamination with an over 200% stretchable membrane and a soft hand offers excellent flexibility. It is applicable for a multitude of stretchy shell type activewear applications.”

  16. Hey Tom,

    Dermizax is a fabric that I have no personal experience with. I think the Toray fabrics bring up a few good points. I do want to be perfectly clear though that nothing I know/think about these fabrics is based on actually using the fabric outside.

    1) The feeling I get having researched this fabric a fair bit is that Toray is making excellent quality fabrics. They sell fabric to some brands that charge a TON of money for their outerwear. The thing about these companies though is that (by and large) their target markets are more wealthy chalet owners than serious skiers and mountaineers (of course this is a generalization). This means that the importance of things like hand feel and face fabric appearance likely take precedence over performance. This idea is echoed in your pasted FAQ above where Toray touts their quality control rather than other, more technical details. I am currently living in europe and have looked at a few of these pieces in shops. The fabric quality feels very high – there is no doubt that Toray is making good fabrics.

    2) Toray has a surprisingly lucid and straight forward website for an overseas fabric house. Each of their various laminates are detailed with constructional techniques and performance numbers based on common standards. That being said, Dermizax NX is mysteriously absent from this site, as is much info at all on this specific fabric which seems very odd considering NX was released in 2010… (one potential reason for this is that Toray is also selling is fabric to other companies that are using it as a “house brand”. Think Patagonia H2NO or TNF Hyvent, but not necessarily those specifically.) What I have found on NX is that it is a PU based fabric that can stretch. I have seen a few places referring to it as monolithic and therefore NON air permeable. This matches up with most of what I have been thinking about the fabric, but it still is a bit of a mystery. I don’t believe those MVTR’s (“moisture vapor transmission rate” – a way to rate breathability) for a second though, especially if NX is monolithic. A monolithic membrane shouldn’t be able to get a 50k rating when NeoShell typically is 20-25k.

    However, due to the lack of info I don’t necessarily trust that NX actually is monolithic. My best guess is that it is microporous PU, which Toray does make under other names (Dermizax MP, some of the Entrant line).

    3) It would be great to test more pieces that use Dermizax. Jonathan Ellsworth has just started getting time in the TREW Cosmic jacket (which uses Dermizax EV, not NX), and we’re looking at some pieces that I might be able to start testing, too.

    Thanks for your comments and let me know if you have any other questions!

    • Thanks so much Sam, you are a saviour.

      Would be awesome to read some reviews – its surprising how hard it is to find an opinion on the fabric given that it is used in a lot of top end garments.

      I own an old pair of hand-me-down, Spyder trousers which use Dermizax-EV. Despite being insulated and not featuring any venting, skinning in them in +ve Celsius temperatures is not a disaster, so they must be doing something right!

  17. Sam, great synopsis.

    I agree with Tom about Dermizax NX and am spiraling into the same abyss. It would be great if someone could shine some light on the Dermizax NX mystery.

    For starters, exactly what is it and how does it achieve such gaudy numbers? Why is there almost no information available on it (especially in the U.S.–I can only take so much Google Translate). But even more curious, if it’s so good, why aren’t more manufacturers using it? If it is being used for “house brands,” which ones and why aren’t they touting 20,000/50,000 ratings? Aside from waterproof/breathability, what about durability and quality control in the manufacturing process?

    There are several brands that use it, or have used it. Most seem to be pricey EU brands though and maybe trend a little more toward the fashion than the functional/technical side of things (Bergans, Kjus, Ortovox, Goldwin, Killy, Peak Performance, Descente, MEC, Spyder, Obermeyer, Phenix). It doesn’t seem that price is the reason no one uses it as there seem to be products available that are in line with the Arcteryx’s/Patagonias. MEC makes a jacket that’s very affordable. There’s also a guy making hunting apparel with it (Kuiu). Here’s a link to his explanation (marketing hype?): http://blog.kuiu.com/2013/08/21/waterproof-breathable-fabrics-how-they-work/#sthash.FqWrRl7Y.dpbs.

    You would be doing a great service to mankind if you could sort this all out.

  18. I have had a Phenix ski coat with Dermizax for three seasons now. It is the best coat that I have ever owned by far. It is definitely waterproof. I am a mogul skier so I sweat a lot and the jacket breathes supremely. And it stretches well so it does not restrict movement much. Also it is quiet, it does not crinkle. I can ski in it from plus 5 to minus 25 celcius comfortably. The reason that I got to this web site is that I am looking for a rain jacket with the same material.

  19. I live in a truely wet environment (northern Ireland) I need pants and jacket that is basically 100% waterproof.

    I was looking at a brand called stellar equipment.

    Any feedback would be amazing

    Many thanks Davey

    • David, I live on Vancouver Island (off the coast of British Columbia) and having spent time in Ireland, I can safely say we get almost the same weather. Very rainy winters, occasional snow. I still prefer my Neoshell jacket, although my Polartec Powershield has never left me disappointed either. I use a Neoshell lightweight for summer (layer in fall) and a heavier weight of either Neoshell (with a high loft inside which traps air, creating an extra bit of warmth) or, just a heavier 2 way stretch Powershield and layer as necessary. To begin with, you can literally pour water on the face of any of these fabrics and it just runs off. It is highly water repellent. Waterproof? In my opinion only rubber is waterproof, and you would sweat so much it might as well have holes in it, as you would be wet anyway. Most of these high tech fabrics eventually need some type of refreshing. There are a few choices to do that, my preference is a product called Gear Aid (wash in or there is also a spray-on type) that is designed for technical water repellent fabrics. All of the above fabrics are very breathable. You can’t beat Polartec…in my humble opinion. I have used these fabrics for years, and have jackets that look great even after 10 years.

    • Hey Dave,

      I assume you’re looking at one of the two shells that Stellar Equipment makes? I’ve no personal experience with this brand and just perusing their website doesn’t offer much insight.

      What I can say is that they employ Dermizax NX for their fabrics. You can see just above your comment a discussion on this exact fabric and membrane. We still haven’t had a chance to thoroughly test a Dermizax NX piece and if anything, it’s industry penetration has decreased since late 2014 when I last took a serious look at the fabric.

      I wish I could be more help on Stellar Eq. What I can say is that if you need 100% waterproof outerwear, your best bet is Gore Pro. It’s expensive, but it’s rugged, very waterproof and decently breathable. Know that making outerwear waterproof is easy though. Keeping water out isn’t so hard, we’ve had effective rain jackets for decades. The hard part is the breathability. I think, depending on what you like to do outside, there are cheaper options than Gore Pro that will also keep you dry in Northern Ireland. For example Columbia has a new rain shell technology that doesn’t rely on a DWR, we can’t wait to test one of these jackets. If you do a lot of high output activity, check out Neoshell for sure, it’s the best compromise between breathability and waterproofness. Many companies have “proprietary” shell technologies that tend to work pretty well. If you need to trust your jacket in safety critical situations, Gore is going to be the most reliable, for the other 99% of us, there are many solid hard shells available for a more reasonable price.

      Hope that helps!

  20. Hey Sam
    You should get your hands on a coat made of Dermizax NX and try it, you will be impressed. My Phenix coat with Dermizax replaced a Columbia coat with Goretex. Both coats keep the water out totally but the Demizax coat lets it out too, making it way better to ski moguls in. I sweat a lot skiing and In my Goretex coat the sweat stays in so going back up the lift on a cold day I get cold. In my Dermizax coat the sweat breathes away so I do not get cold on cold days. I can wear the Dermizax coat on warmer days too, up to plus 5 Celsius. The Gortex coat is only comfortable at minus 5 or colder. Plus the Dermizax coat stretches while the Goretex is stiff. I personally will never buy non-breathable activewear again.

  21. Thanks for the link Sam, I will look at the Trew web site. Cy’s experience with Dermizax is the same as mine. My jacket is three years old now and is holding up well.

  22. I got my wife a Kjus Lily with Dermizax(not sure if its NX or EV). Shes a complainer, and absolutely loves everything about the jacket. We tried Mountain Force and Karbon, but settled on the Kjus due to body type fit(and color of course). I skied in my 9yo Spyder Team Venom and she in her Kjus(when it was raining at the base and snow/sleet at the peak). After 3 hours of skiing she was completely dry and didn’t sweat. The inside of my jacket was dry but outside was soaked, hers, nothing. I have since upgraded to a Phenix with Dermizax EV but have not yet put it through the East Coast skiing test. I would still buy a Spyder, but the latest jacket styles didn’t really interest me. I do love their full zip Xt.l pants which i have had for 10 years and 0 problems.

  23. Found this thread by coincidence, happy to hear that some of you are at least considering our brand Stellar Equipment ;-)

    Here’s a pretty substantial review that covers both Dermizax NX and our products. It’s not completely unbiased as the photographer who wrote it gets his gear for free from us — but I think you will find it both relevant and informative nonetheless.

  24. hi sam. thanks for the usual beyond thorough blister report. i just stumbled on this 5 yr old thread today.

    i think the columbia product you referenced is called Outdry. i have 2 items with this technology : boots and a jacket. the boots are lightweight 3/4 height hikers (just tall enough to evade your wrath…). fully waterproof, but much more importantly, more breathable than any other membrane shoe i have used. ZERO swamp foot. comfortable to leave on all day.

    the jacket has not seen as much use, but i am hopefull for high performance. i have used it skiing. and, though i am not fond of the fit or the features, the breathability is excellent. this from a fat old PNW tele skier, aka a sweat factory…

    keep up the good work !

    • Thanks for the response, Steve. We are certainly interested in Outdry and have a chance to get out in a few pieces. Stay tuned for reviews!

  25. I also would be interested in seeing a breakdown of the new exterior membrane options that do not require DWR, such as Columbia Outdry. I have a Columbia Outdry jacket that I use for bike commuting and chairlifts. It is superior to anything I have used prior for waterproofing, with no DWR it never “wets out”. However it is not breathable enough for me for backcountry skiing. I would love to see these materials compared to interior membrane options.

  26. I know it has been almost 10 years since the article was published, but I was wondering if anyone could provide scientific sources for all this data? The article itself is wonderful and I absolutely loved it, however, I would like to read more in-depth about it.
