Four companies made bold claims about cutting-edge waterproof technology in 2011. So we gathered a dozen rain jackets with the new fabrics and put them to the test in a head-to-head challenge. Verdict: We've never worn a more breathable crop of shells.
The good news: Textile engineers have developed advanced techniques for testing a membrane’s breathability— that is, the rate at which moisture vapor moves through a fabric—which helps companies measure and improve performance. The bad news: No one agrees on which method is best, and brands tend to use tests that show their products in the most favorable light (surprise!). So when you shop for raingear, you’re going to see catalogs, hangtags, and websites promoting various numbers that are meaningless if you don’t understand the tests. Here’s a quick primer to help you decipher the performance claims.
>> MVT (moisture vapor transfer) test: This measures how much moisture (sweat) vapor moves through a membrane in a given time period. The higher the number, the better the performance. How it’s done: The material is stretched over a cup (though even this changes: inverted cup, upright cup, membrane touching—and not touching—the water), then the volume of evaporated water is measured.
>> RET (resistance to evaporative transfer) test: Also known as the “sweating hot plate test,” this measures how much a fabric resists letting moisture vapor through. The lower the number, the better the performance. How it’s done: The fabric is saturated, then placed over a heated, porous metal plate (intended to mimic human skin), and the volume of evaporated water is measured.
>> DMPC (dynamic moisture permeation cell) test: This test measures how much moisture moves through a fabric at various humidity levels. DMPC results are in graph form: The best results are horizontal lines that show consistent breathability across all humidity levels. How it’s done: Fabric is stretched through a chamber, creating two separate cells. Humidity and pressure are controlled and measured on both sides; proponents say it best mimics changing real-world conditions.
Waterproofness
While companies agree on how to measure waterproofness (a column of water is stacked on top of a fabric until the fabric leaks), they don’t agree on what constitutes waterproof. For instance, Gore fabrics routinely rate very high in water column testing (20,000mm or higher—picture 20 meters of water stacked on a membrane). Other companies, like Polartec, believe that that level of waterproofing is overkill, unnecessarily inhibiting breathability. As a result, the company engineered NeoShell to have a 10,000mm rating—and our testers reported no leaks.
Just wondering if anyone has tried the Helly Hanson Hamm jacket. They make rain gear mainly for work but the HH Hamm is used by some backpackers. I like the long torso as it comes down over your gluts and wont ride up. Claims to be ---breathable-- but I think the breathable thing is overrated as you will sweat anyway and usually get wet inside regardless of what you are wearing for a shield. I am now more interested in rain proofness ( I know ) and durability. I gonna give the HH a try.

Scott B, you are clueless. The reason that nobody talks about water repellency is exactly what you describe; a coating. Go buy some Nikwax TX Direct, spray it on your '95 Starter Jacket every day and you will be happy. If you want a WATERPROOF and highly breathable jacket, buy one of these.

Funny that none of the "tests" that Backpacker performs has anything to do with water repellancy, which is the only reason you would buy a rain shell. I've owned Northface and Marmot jackets that failed in their second year--because all the repellancy is due to special coatings that quickly bleed off, regardless of whether the jacket is worn. Forget treating the jacket with a new chemical repellant, as it just doesn't work (we tried it with multiple jackets). C'mon, Backpacker, be more than an industry shill. Do the right tests, and screw "breathability." I want to be dry, not hypothermic like when my first rain jacket failed.

If you're not looking for style/fashion and just pure quality in a rain jacket, I highly suggest having a look at http://www.raingearpro.com/. The site isn't much to write home about, but a lot of us swear by the product. It's very popular with fishermen, construction workers and other people who make their living outdoors.

Check out Eddie Bauer First Ascent gear pretty good stuff and better prices and goes on sale frequently for 20-30% off. The BC-200 is a newer waterproof shell that is supposed to be nice. My $.02

I would like to know what actual tests were and what method was used to "measure" their results as stated by the Testers that the jackets were 20% to 30% more breathable than anything they used before and what as the "Base" figures from the preious items they wore before??
Also how do you know the Manufactuers supplied Data and information was entirely accurate versus Marketing baloney or Claims, so it appears that you just took for "Granted" like Pack weights and sleeping Bags temperatures that what the Manufacturers provided was truly accurate?
So then, why do you bother to claim you test this stuff,,it appears your just regurgitating what the Company's tell you to regurgitate...Oh how I pine for Mr. Rodale to be alive when his Magazine was a creditable source of information...and I was one of the original subscribers...so I know...

Why weren't any eVent jackets tested? Information I have seen indicates that eVent is much more breathable than the membranes in the test.

THOSE are the jackets you test? Mtn. Hardware and Columbia are the same company for starters. What a terrible comparison. This email goes out to, what, thousands, millions of people? And most of them will just see the tag line of what is best. Next time take the time to actually compare and contrast the jackets in more than a paragraph... this is what makes Consumer Reports so popular, f.y.i.

It's funny that when BP does a comparison of a few items, readers want more. I guess that is why the annual Gear Guide is so popular. Some people expect the content of the gear guide in every review. That's ok and I suppose I do the same thing. What I find most helpful in the gear reviews are those little things - plusses & minusses - that let me prepare in my mind how a particular piece of gear will perform in certain circumstances. For example, I know that every jacket has limitations, like how it breaths when I am climbing in a cold drenching rain verses dry windy snow or summer humidity. Understanding those little things help me plan better and make me a better backpacker.

I too have an Arc and I am disappointed that some of the other high end makers didn't make it at least to the testing in this. The article is interesting but it is misleading by being named the "Best" when you only tested some.
FWIW - My Arc DWR failed within the first week. It has been retreated by Arc and I am wondering what it will be like next season. If it fails, Arc will get MANY bad reviews popping up all over the place.

Their's no way these jackets are worth that kind of money.These companies are testing the market for suckers that will pay for that kind of teckie gotta have the newest apparel. These jackets are made in some slave driven country for 30 cents a day workers. The profit these companies are making is disgusting. Anybody that would pay that kind of money should save the money for psycho analyst.

Mark, the same happened to my top of the line Mammut Goretex rag. Had sent it in, been told the membrane was torn, and warranty declined. Never again. My next one will be either a Sympatex or an eVent jacket.

Checking out waterproof breathable shells AGAIN this year - you can have both of my 2-years-old like-new, utterly useless, actually dangerous Patagonia shells. I'm lucky the weather broke just right. Patagonia apparently forgot the waterproofing entirely. A $10 K-Mart windbreaker has all the water-shedding ability of my $225 Patagonia soft-shell, the $120 shell meant for the bottom of the Camelbak is a little better - still life threatening in a drizzle above tree-line. Just starting to look - open to suggestions.

The goal was to test the top hardshells (waterproof/breathable shells), not necessarily find the most affortable. I've got the mt hardwear Jovian shell, super sleek design, light and comfortable despite what the article says about it being "stiff". Ponchos are waterproof, but so are windshields, breathability is an issue for those who really spend time working hard (backpacking, running) in wet weather.

I found this review helpful, and the effort that went in to testing it. However, Patagonia, Arcteryx, and other brands also put a lot into research. I would have liked to see more of the different models and brands tested. Is there a way to get more details on your research? I live in the Pacific Northwest, and so I need a shell that is secure and "bombproof" in heavy rain, and also in high-altitude high-wind conditions.

I bought OR's Foray jacket last year for a 4 month stint in Montana's northern rocky's It handled every thing from a rogue hail storm to a 2 day soaker. And it took the abuse of 120+ days of harsh trail work without a tear

I have an Arcteryx shell and the DWR failed almost immediately unfortunately and the jacket wetted out. I doubt that is typical of Arcteryx (at least it better not be) which is why it would be nice to see some other brands including the Arc in this review.
