That was a well put together piece. I teach outdoors and have done for 25 years. My Paramo Anaolgy jackets have worked longer in more environments and outlasted every other (and I've tried everything!) jacket I have. The core truth is that nothing is waterproof always and everywhere. Paramo Analogy (well looked after) is drier longer and in more places and situations. Our entire outdoor staff (20 outdoor teachers) are issued Paramo.

Great comment thanks!

Slight terminology correction: liquid water on a wetted out face fabric is just liquid water, I incorrectly referred to it as 100% humidity. The term '100% humidity' is best to only be used to describe moist air at the point it can't accept any more moisture. Much more on this in my next video.

the problem you described in the video can be solved by higher air pressure inside. In general, vapor pressure near body is higher than outside because body is hotter. As result vapor migrates outside. But if outside temperature is close to body temp, vapor pressure outside can be higher if humidity is high enough. This is problem for both systems: membrane and 'fur'.

Thanks! I just got that from the Wikipedia page: en.wikipedia.org/wiki/Gore-Tex

There's a sentence in english, that explains waterproofing and it goes like this. "..you simply suggest for the droplets to take another path.." This is what water proofing is.

I also have a Paramo Alta III for winter time and I love it. But honestly, as soon as it gets over ~15°C outside, you just cannot handle the thick, warm and heavy fabric that is the nature of Analogy products. This is where I still use my ultra light GoreTex (packlite) jacket. It also seems that you have quite a lot of money to blow on waterproof jackets. Paramo solutions (and GoreTex Shakedry) hover around 300 to 400£, which is a notable sum considering GoreTex starts at around 180£ (with cheaper membrane products around the 100£ mark). Not everyone has the money to "buy into" Paramo products. I hope that with popularity they will get a bit more affordeable without sacrificing on labor conditions and the environment. Cheers!

Totally agree. I am a Paramo fan and have used their product for a long time. Also look at Ventile jackets as another alternative to GORE Tex.

Ventile was developed before such compounds existed and was supposed to work by getting wet. The older version of Ventile produced in Switzerland used the toxic PFC treatment but the organic version is treated with Nikwax DWR according to the brand which made my jacket. I have let this wear off and won't be renewing it as Ventile needs to absorb water in order to work. In prolonged heavy rain one won't be totally dry in either a Páramo or a Ventile garment but, having owned both I've sold ALL my Páramo stuff and am now solely using double Ventile without any unnecessary DWR. I also no longer own or want any Goretex or similar garments.

Your skin is not meant to be completely dry in any case - rain is uncomfortable because it is cold afaik. For everyday use (not wearing for a full day/intense activity regularly) I believe the old style of coat is the best. the maintenance factor is really the thing that drives me away from these coats - to hear that I will have to reapply the water repellant is frustrating.

The issue with the down jacket is we often have wet and cold weather in the UK so I think I'd like to get the Paramo insulator that is designed to be worn over the top of the normal paramo and it doesn't matter if it gets wet.

The only way is to use a soft fabric thats bendable. Then get the roof tile method of lots of fabric panels sewn on . This obviously will work best standing upright. But at least its breathable when working or hiking.YET if you are at rest the tilies will rest downwards and shed the water Edit.

The mannequin text would be aced by Gore-Tex, or a plastic garbage bag. You explanation of how the analogy fabric works with bears in the background (how does it shed other liquids?) seems to imply there are hair like fibers, that shingle or something. Overall, though, it just sounds like waxed cotton. I have been wearing GoreTex jackets for 40 years. But for a lot of that time they hadn't fixed the seam problem. So simpler, kimono cut, ideally UK made coats, or Barbour waxed Jackets, where weight allowed, have been better for the rain. Chouinard figured that out in the 80. Mainly, what GoreTex did was 5-10X what people paid for a "technical" coat. And folks like Patagonia that didn't have to cough up to Gore, were laughing. Where GoreTex shines is it will keep you dry, once they figured out the seams, but it is no better than a plastic bag, but it does breathe when not wet. So it is fantastic for Ice climbing where you mostly have wind, but also running water. And today, waders, where the part that isn't submerged, or when you are moving to a stream, will breath. Seems like a lot of the same old, same old.

The inner layer material is actually the bit that does the work. It's called the 'pump liner'.

Over time, all of my winter jackets seemed to lose their ability to repel water. I suspect that is because a waterproof spray coating fails over time with washing and exposure to rain.

Edit after watching the video: Yah I get the desire to have tests that allow active pumping materials be able to be tested. Though to be fair if we really want the best performance we would wear ponchos with very large baffles that allow us to turn away from the rain and lift them to release the hot air every now and then. But that results in an insanely unfashionable thing, at least in most current cultures. As for what that poncho should be made of I beleive much more in full membrains than active pumping since a poncho with baffles overlaps heavily with the problems active pumping helps mitigate, yet is way better at them. Vs the problem of heavy hard wind and rain which active pumping is weak to and membranes are alot better at.

I like the concept of Paramo overall (I even bought a Paramo pump liner from Scotland some years back). My two main (and big) issues with Paramo are 1. the price-these systems are quite expensive and 2. the notable lack of durability of the DWR/hydrophobic coating (Nikwax) that is used. I both thought long and hard, and did some experimentation with much less expensive but more durable solutions. So far, my best solution is the following: Buy an inexpensive (but fabric based, so not too inexpensive!) poncho. Next, cut out a large rectangle from the front of the poncho. Basically from almost the neck down to the waist, and as wide as your chest. (Typically will be something like 1 ft wide x 2 ft long or so). Get an uncoated, pretty breathable but not ultra breathable, decently light polyester fabric (smooth taffeta works best). Then get some 100% clear silicone caulk and thin it very well with a good solvent (like naphtha). You want to thin it significantly more than, say if you're seam sealing or re-coating a silnylon or silypoly shelter. Soak that polyester fabric that is approximately 1 ft wide by 2 ft long in the thinned silicone, then let it dry/cure outside. To that, we're going to sew some inexpensive medium weight non woven polypropylene fabric of the same dimensions. You know that kind that some inexpensive reusable grocery bags are made out of--the kind that is rather porous/breathable. Then to that, you're going to sew some kind of DWR treated mesh type fabric i.e. ultra breathable. If you want something really cheap, take some of the above thinned silicone caulk and dunk some nylon tulle in it. Personally I prefer Ripstop by the roll's Monolite fabric or Dutchware Gear's Cloud fabrics (same stuff btw)-much more durable than tulle, regular mozzie netting, etc. Sew that ultra breathable fabric to the above composite. Then sew that, you guessed it, to open part of the front of the poncho (treat the seams with the same thinned silicone). Even with these 3 fabrics sewn together, you should be able to suck or blow some air through all 3 layers-not struggling but not super easy either (breathability should be like a good windjacket, or to put it into quantifiable terms, the CFM levels should range somewhere between 20 and 50). That's key. If it's not, you've either used too tightly woven polyester for the first fabric _and/or_ you didn't thin the silicone enough, or if the latter (too breathable), the opposite. Take two coffee filters, put them together and breathe through. That's about what you're aiming for. Almost done but not quite. Importantly, wear a fishnet as a baselayer (preferably a polypropylene based one-fastest drying garment known to humanity). Over that, wear a thin, well wicking polyester (preferably low spandex/lycra type content) l.s. baselayer shirt of that. The combination of of mechanical venting of the poncho with the breathable but highly water resistant front panel will, in combo with the right baselayer combo, do you good in a wide range of conditions. Some water might get through, like with the Paramo systems, but your body heat will quickly remove it. If it is particularly heavy and sustained rain and/or on the cold side, wear a non wicking polypropylene l.s. baselayer (like Terramar makes) over the polyester baselayer (which, as mentioned is over a fishnet true/first baselayer). I have tried many different things. Nothing I've tried so far has compared to the above. It does require some experimentation and holistic thought, but really isn't hard to do. I know people don't like the looks of a poncho or the potential flapping. As to the first, I don't care at all (how immature/shallow, function should always trump form). As to the second, I put a piece of shock cord connected through a few loops that cinches the back fabric around my pack tightly and with the excess, I just tie it lightly around my waist-hence little to no "dreaded" poncho flapping. Meanwhile, the silicone coating on the polyester face fabric will last a long time and be quite durable (unlike a Nikwax coating or any traditional DWR type coating. The silicone coating is much more durable simply for the fact that it is MUCH more thick than most DWR coatings are). And you can do all this for pretty inexpensive (provided you already have or know someone with a sewing machine). You can also use tyvek "kite" cloth instead of the non woven polypropylene, my first iteration used soft tyvek kite cloth fabric, but I don't recommend this as this material is surprisingly thermally conductive (about the same as water if I remember correctly-look up HDPE material's thermal conductivity) and condensation can build up on it easy. Also not as breathable as the nonwoven PP material, while the PP material is quite thermally non-conductive and thus better in cool + wet conditions.

@justinw1765

Despite my issues with Paramo, I still liked your video. It's always good to think outside of boxes, to question the mainstream, etc. Btw, if it is not clear in the above. The silicone coated polyester fabric should be the first face layer that is facing the rain/weather, the PP or tyvek cloth should be the next "core" layer, and then the ultra breathable mesh layer will be the closest to and facing your body. Multiple reasons for this. The silicone polyester coated fabric will be stronger and more durable than the other two layers, and it will be much more UV resistant than the PP or Tyvek cloth layer (on a side note: black colored PP material will last much longer with UV exposure than white or very light colored PP material). And the mesh layer just doesn't shed water well enough to be on the outside. It is mainly there to protect the core PP/Tyvek layer from body oils (especially when you touch the garment with your hands), friction with your clothes, etc. Once in a blue moon, you will have to cleanse, degrease, and rinse very well this garment to bring it back to 100% function. But far less often than you would have to do a Nikwax treatment on Paramo. Also depends on how much or little bushwhacking you do. If say you're spending a month in Alaska, walking through wet brush etc constantly, then yeah, you will probably need to do the above after. If you primarily walk on trails and don't come into much contact with plant matter etc, maybe once a year or every two years. Walking through wet brush and the like, removes Nikwax and traditional DWR coatings very quickly btw, especially when combined with heavy sustained rains. My system isn't "perfect", but its near to being the closest thing until unobtanium super materials are developed that are super hydrophobic, while being ultralight and quite breathable. Don't hold your breath though.

So my hat is a WPB hat when I need it, and a very breathable Sun hat when I need it. The fabric covering does look a bit funny, but it makes the hat more wind shedding, and adds very little weight to the overall system. I'm a systems thinker and love multi-purpose items. If you want to check out my very first, very crude iteration, check out/look up back packing l!ght "odd/unique but very breathable rain gear system".

@@BenVallack If you want to look up my very first iteration from geez, almost a decade ago now, look up backpacking light odd/unique but very breathable rain gear system. (it's on a forum). (I was new to sewing, fabric cutting, etc at the time, and it's not very pretty looking since I was in a rush to get it made for my Colorado Trail hiking trip. Also note, I did not treat a polyester fabric like I recommend in the above, but rather used a silnylon fabric that tested very poorly as to HH, and then ran that folded up under a non threaded sewing machine needle to puncture the silicone film/coating on it to make it more breathable).

Are there any animal products in the nikwax coating?

They don't tell you what's in their care products, and what their clothes are made of. A lot of claims (sustainability and performance) and patented names for things, but very little real information on their site. I like their products and ideas, but being so "secretive" doesn't look good. I hope they can be more transparent

They say it's biodegradable and it's a polymer. www.nikwax.com/en-us/how-nikwax-works/ I think the fabric is just polyester.

How does that compare to a Buffalo with Pertex?

I think they are more for really cold and wet situations. They keep you warm even when wet, and are designed to be worn next to skin. I don't think they claim to have any directional behaviour. Less practical as an everyday coat if you have to be naked under it!

The jacket he is talking about, retails on the website for $450, must of just missed that point. You get what you pay for. A lot of people can’t afford that.

That sounds way off - I paid £240 for mine. Definitely not unusual for decent outdoor gear and especially reasonable value for something that lasts over 20 years.

i just want a jacket made from the shit they make umbrellas from. i never had a leaky umbrella. 200euro gortex leaks in 5 mins.

Cheap compared to Gore-tex gear!

Lot of weatherproof clothing uses PFC / PFAS / forever chemicals which are a serious pollution concern since they don't biodegrade and instead accumulate in the food chain. Paramo has rejected using those chemicals so they should be applauded for that.

Plastic poncho still the best. 100% waterproof and breathable armpits. Also fits a pack.

Thats for shure a real problem. Especially considering that you cannot wear it year round, because it's quite a warm jacket, the price is really steep. But I think my for my usecase it was worth it. Your mileage may vary

Gore-tex doesn't work without spraying it with repellent either, and also heat to "activate" the tech. it's completely stupid to think it's an everymans fabric, when it's only makes sense for professionals. gore-tex only works in certain conditions, and I can't see why ppl want them when everything else is better.

"That means, the air inside the coat can never be dryer than the air outside the coat" is utter bs since it completely neglects the temperature differential. since your body always produces heat, this heat can be used to dry the air within the coat even in high humidity conditions outside the coat, as long as there is a temperature differential. This is famously put into effect in ecwcs gen 3 suits but known by anybody in rainy countries such as UK or Ireland who heats up their home in order to drive off humidity that could cause mold.

To dry out the inside the vapour needs to leave the coat. You're correct in that a temperature difference will make the moisture want to leave the membrane - but the problem is if the air is 100% RH on the cooler air outside - it will turn to liquid as it tries to leave when it hits the cooler membrane. Some might still escape and turn to condensation on the outside of course so this is a simplified argument - but as far as I can see if the temperature is equal then you won't get any transfer (no vapour pressure gradient) but if the temperature is different you will get the vapour pressure gradient but then you get condensation! The situation I'm talking about is only when it's actually raining and the outside air is at 100% RH. If the air is dryer then it can accept the leaving vapour without it condensing.

@BenVallack

Heating your house prevents condensation on walls, it doesn't make the air any 'dryer'. It technically reduces the relative humidity due hotter air being able to hold more moisture in the air - but that same moisture is still in the air. Warmer walls means less condensation and warmer air means a higher dew point. That's why you get less mould when warming the house - if I understand it all correctly! To remove moisture from the air, those vapour molecules have to go somewhere.

​@@BenVallack It's a great argument, i have to admit. And i suppose it would largely depend on your defenition of "dryer". Since hot air with the same amount of vapour would still have a lower saturation than cold air, i.e. feel dryer and be able to absorb more additional humidity from sweat a.s.o.

@jonabub

16 күн бұрын

@@BenVallack Yes, if the saturation is at 100% outside and if this is accompanied by a temperature differential the vapour from inside will tend to condensate outside. But since the vapour needs to cool down first this will not necessarily be immediate. Also whether the vapour has to be driven off through a membrane or just pushed out with movement and replaced with less humid air that then heats up is depending on the structure of the clothing or isolation. I tend to prefer "fluffier" and more open clothing such as a fleece for that matter since it allows for good air flow. Although windy conditions would make a combination with a less breathable and more air tight fabric necessary. In windy conditions in turn there is almost never a 100% saturation and the vapour would be dispersed before it gets to condensate. I suppose since we are looking for dry feeling rather than saturation levels the best clothing is a function of temperature gradient as well as breathability. Gor Tex is bad at both and only marketing. Ecwcs and similar systems work best for me but i think paramo fits in there somewhere.
