That was a good test. The people crying foul are assuming that you just took your jacket out of the dryer, put it on, and then ran out the door and started running. In the REAL world, you would be wearing it for a while and there would be moisture already in the fabric anyway. In the REAL world that is a pretty good test. Event is just popular because it's the little guy against the big company.
This demonstration is flawed. What happened was that the fabrics were put over the hot water and were left to sit for a little bit. Both fabrics were allowed to heat up, so what happened when he put the glass down was a transfer of heat and quick condensation, not breathability. What should have been done is that he put both the glass and the fabrics on the cups at the same time.
I didn't like this test. If the fabrics were already moist, the only transfer would be from the fabric to the glass, not through the fabric to the glass. I would want to see both fabrics heated to dispel any moisture, then attached to the glass, then placed on the water with the glass.
surely if there needs to be a driving force its diffusion rather than evaporation, I'm sure this guy works for Gore-tex and at the end has pretty much just said event works better in colder conditions 2:26
@16andsmoking The fabric is full of tiny holes, the holes are 700 times bigger than a water vapor molecule . However, the holes are 20,000 times smaller than a drop of water. So basically the vapour molecules can escape but the holes are too small for water to get through.
It would be interesting to try this: 100 people as similar in build, fitness level & gear as possible meet up for an early November hike in Western WA Cascades. (Slushy) All start up the same trail simultaneously 1/2 the group wearing one or the other garment. Measure garment weight at the trail head & at the top. The one that gains the least H2O weight, breathed the best and wins. Lots of other ways to test as well - all more entertaining than the old fabric on cup trick.
I'm not convinced the sales guy is convinced. His body language indicated defensiveness & irritation. A classic staged test, it reminds me of kitchen gadget hockers at county fairs - only not as entertaining.
So they transfer water vapor - so what? So do countless other fabrics.
One thing I've noticed about this test is that they seem to wait a considerable amount of time before throwing the plexiglass on top. The way this "test" is structured, of course it's going to make gore-tex look good. That being said, they're both excellent materials, and I own both and love them both. I may be an eVent convert though....
meh. The better breathability isn't just some marketing B.S. It was the finding of a US Military test. The Gtex sales guy even admits that Gtex requires you to already be hot and sweaty for it to breath and that Event doesn't. Event still works when you are cooling down, Gtex stops breathing before you're completely dry.
The guy actually tries to make it sound like ability to breathe, before you are covered in sweat and not having to take it off to get totally dry, are not superior features.
Hmm. This really doesn't show anything. Just a couple of pieces of plastic fogging up. The result on the plastic would be the same no matter how different the breath-ability of the fabrics were.
i'm not convinced that there is as much wapor on both. a wall seems as black if painted with a brush or if you throwed the entire pot. there is a study of different membrane in laboratory that say for 55%humidity top sample and 5% bottom sample : event 5000+mvrt, gtx xcr 1500+. and for 95%top 45%bottom event the same, is constant and gtx xcr 3500+. still large far below.
The US army did tests on both products and found that eVent fabric breathed around twice as fast as any other waterproof fabric and I assume they didn't just stick it over a glass of water and conclude their findings from that alone (or even at all). The military was just looking at the best product to use, not some marketing spin to say so I trust their findings more than the marketing/product guy from Goretex. Sure Goretex came out earlier than eVent but eVent is the better material to use.
The US army rejected the HK416, a far better weapon than the M4. Delta Force bought a lot of 416s. Again, the army chose the ACU over another camo pattern that's far better. So I would take any US army test result with a grain of salt.
I'm no pro gore-tex or pro-eVent. This is just my opinion.
@mateodeleon2000 Those are examples of the US Army choosing equipment despite it's testing results showing another products to be superior. Not that US Military testing is flawed. Your argument is invalid.
Just because this experiment is not capable of detecting a difference in breathability between the two fabrics, it does not prove that the breathability is the same for both. There is no way to tell how great the difference in breathability would have to be for this test to distinguish between the two. The test is also less interesting because it is carried out in a low-humidity environment, where breathability may be greatest, but you would not be wearing your waterproof clothing anyway.
Way to not show anything with your "experiment". The plexiglass fogs up at "exactly the same time". Try bigger cups and a bigger piece of plexiglass so you can see a difference in the vapor transfer rate. They probably have some legitimate testing equipment in their lab that facility, but they don't want to show you that.
I work at an outdoors shop and from our experience we found eVent more breathable in cold + damp environments (UK!) compared to Gore-Tex - where as they are both very similar in breathing in cold + dry or Alpine environments
what a pointless argument for people to bring up , if both breathe then who cares if there is a slight difference, i woudl go with goretex because they have been making it for longer and that is always important
If youre giving off that much moisture, you need to unzip your main or pit zip. The good thing wtih eVent is that competition drives prices down, which is good for everyone.
As I contemplate new boots KayLand event vs. everything else Gore-Tex, I know I'm not planning to take plastic cups of water and a couple discs of material out on the trail with me. Nice fancy marketing by Gore-Tex. They are as slick as the drug companies with this demo. I'd rather see research than a magic show.
I have a pair of KayLand boots and they are fantastic. I've worn other boots with GoreTex and they just don't breath as well. Proof is in the field and I have all the proof I need.
i think what they meant jason was the test is so basic and arbitrary it doesnt actually prove anything other than as you say, both transfer water vapour, which we already knew. it doesnt even begin to look at the RATE of transfer. i.e the area and vapour transferred are too little to prove the difference.
hope i was clear in what i meant there! :)
oh and dont get me wrong i dont think the difference is massive enough to matter to most people in most situations
I do not own any Event indument but my last goretex jaket served me for 10 years and still be totally waterproof whitout any care (just machine dry after wash). I have buy another new only because it is really worn and i have repaired it to much time; loock like a puzzle...
My machine is a little bit old, have "light, normal, and intensive" i always did normal for the jacket but i do not know exactly what temperature is it. Anyway i think is around 60-70° Celsius (or little more)
As some others pointed out, in this uncontrolled test one has no idea of the actual volumes of water moving through each fabric in precisely how much time
Kudos for the video, thanks for posting Jason, I always appreciate your informative videos.
It might be a better test if the material was already up against the glass plate and they were put over the water together. This is because moisture is already moving through both the materials before the plate lands. It would more acurately measure the time it takes for moisture to pass through the material onto the glass plate and therefore be a better test of time vs moisture movement through each material.
That was a good test. The people crying foul are assuming that you just took your jacket out of the dryer, put it on, and then ran out the door and started running. In the REAL world, you would be wearing it for a while and there would be moisture already in the fabric anyway. In the REAL world that is a pretty good test.
