Anybody using E-vent?

post #1 of 12
Thread Starter 
I've been looking at picking up a waterproof/breathable hard shell and seems like this e-vent stuff is for real. Even had a rep for one of the high-end outerwear manufacturers tell me off the record that it "blows away" Gore-tex. Since only a few smaller companies are using it so it's kinda hard to shop for. Can anyone recomend a particular brand that I might want to check out.

My SOS jacket is E-vent. It is quite nice and kept me dry.

how does it "blow away" goretex? In it's breathability? it's waterproofness? the combination of those attributes?

Personally, I don't fret it so much anymore. it's either waterproof or it's not. If it's rated below 20,000 I know that it will just require more treatment to make it more repellent in storms. Even goretex needs to be refreshed as the nylon shell's DWR can deteriorate.

Breathability.

fleece is more breathable than goretex too.

Search on TGR for eVent, there was a lot of discussion over the summer about it. A shell came up on SAC, and I took a chance and got one. No question whatsoever it's more breathable than any version of GoreTEX, Plus/Pro/XTR or whatever.

And no worries on the the waterproofness either, I wore it for few days of hiking and walking in steady and heavy rain, it was as waterproof as anything I've seen, no wet out at all. This was with a brand new DWR finish, so I'll expect that to diminish over time and use, and I'll just re-apply it with NikWax.

It was pretty nice to see it live up to all the glowing praise written about it. GoreTex at one time was probably the most breathable textile for waterproof outerwear. But anymore there's a lot of hype and marketing associated with it. It's all relative too, I don't think there's any compelling need to ditch existing GoreTex shells used for skiing, the breathability works fine there. For strenuous aerobic activities, though, you could easily tell the difference between the two fabrics, it's like night and day.

I've tried some eVent jackets for a variety of activities like jogging, walking, hiking and sports.

I do agree it is more breathable that Goretex while maintaining the same waterproofness, however, it is not the end-all to jackets. It will let water vapor pass through its porous membrane much faster than Gore, due to the lack of a complete PU coating over the membrane. But, that said, we're only talking about water vapor: the sweat has been sitting against your body/in your liner, waiting for your body to heat it up so it can become vapor and pass the membrane. Any liquid water--the sweat beading up against your skin and the jacket--will pass incredibly slow by solid state diffusion through the membrane. In addition, with complete windproofness, you're going to lack the the air sweeping away the moisture.

That being said, if you're looking for a Waterproof jacket, get eVent, because it is the best right now and a good increase over Goretex. Just know that physically exerting activity will still give you that clammy, wet feeling in your jacket, albeit a little bit after Goretex would have.

While I've heard rumors that the eVent jacket--with its oleophobic membrane rather than PU coating--isn't as durable and is more susceptible to dirt/oil ruining the membrane, I've not seen nor experienced anything to give me or others that impression.

The water vapor vs. liquid sweat is accurate, but you didn't mention the wicking effect of a light base layer. One doesn't wear a shell directly against the skin for any activity, aerobic or otherwise. Pata-gucci Capilene comes to mind here.

The reason they refer to a light polypropylene top as a wicking layer is because that's exactly what it does. It wicks the liquid directly from the skin, and that liquid evaporates very quickly (as compared to wool or cotton). Through a mid layer of fleece if present, and then through the breathable shell. If all the pieces are working right, you never really notice the process.

they say it is better than the gore tex xcr...but pro shell is supposed to blow away xcr in terms of breathability

For an objective comparison on how these membranes perform, check out:

Subjectively, I have eVent, Goretex 3 layer, Goretex 2-3 layer, and Goretex XCR shells, and they all work great. All four of them are completely waterproof, windproof, and breathable. I feel that the Helly Hansen eVent shell might be the most breathable of the bunch, but I'm not sure if that's real or just due to my preconceived notions.
