Breathable fabrics work because a pressure gradient is generated when you sweat and generate warm water vapor which is higher pressure than the dry air outside. Breathable fabrics don't work well when the relative external humidity is high (like on a river) and are even less effective when the fabric gets saturated (like the first time you get hit with spray or roll). They also depend highly on the Durable Water Resistance (DWR) coating causing external water to "bead" on the surface so that it doesn't clog the pores in the PTFE membrane and in my experience that DWR only lasts about half a dozen times on the river, but maybe that's because the rivers I paddle are highly polluted with potential solvents. Maybe your experience is different.
That being said, eVent is known for being highly breathable - so high that some companies use it as a pressure relief "valve" in drybags. But the flip side to that is poor water resistance. The rumor is that NRS recalled their eVent drysuits, maybe someone else on here can confirm that.

- disagree, at least for the SE DangerJudy New
-
- That's kind of a different issue though... DavidWeber New
-
- I have a nylon kokatat that I never wear DangerJudy New
- You obviously have a flawed boat/skirt combo jkodadek New

- Wish I knew your secret.... hardboater New

 Can the membrane in breathable equipment tear without the outter shell tearing? hardboater New -
- Yes... jkodadek New
-
 Well, in either case, I guess I'll be sending mine back to the manufacturer for repair or replacement. hardboater New -
- I'd wash & dry it first, then refresh the DWR. <NT> tcookson New
- Well... KenDriscoll New
-
- Which is what I *would* have said had I the time to articulate it properly. DavidWeber New
-
- but you said they were a waste of money... HillHarman New
-
- Portaging I'll give you... DavidWeber New
-
- Have you ever used a goretex drysuit/drytop? HillHarman New
-
- The big question...has he ever used a goretex dry* on a big mission where there is lots of scouting, safety, and portage jkodadek New
-
- Well, your little dig aside there... DavidWeber New
-
- research in a lab means nothing HillHarman New
- Well, first of all.... DavidWeber New
-
- You still aren't answering the question... HillHarman New
-
- Well then don't take my word for it... DavidWeber New
-
- Find an experiment where they've faithfully replicated a kayaking environment HillHarman New
- Basically. IMO, breathability is important in a drysuit but isn't worth ... davegg New
-
- ???Overkill??? RandyH New
-
 Slightly different deal there though.... hardboater New
 What a ridiculous assertion jkodadek New -
- Hah! You're right I was being melodramatic. But I stand by it... DavidWeber New
- Thermal gradient (not pressure) is the key to Gore-Tex breathability snowwrestler New
-
- Gore-tex can breathe under water!? DavidWeber New
-
- It's true snowwrestler New
-
- Huh... DavidWeber New
-
- Well if you understand the chemistry, the parlor trick isn't necessary <NT> snowwrestler New
-
 And just so you don't think I'm making this up snowwrestler New -
- The author of this article has NO CLUE what he's talking about. DavidWeber New
-
- And you do? snowwrestler New
-
- You sir, are worse than Hitler. DavidWeber New
-
- Jane you ignorant slut snowwrestler New
-
 LOL! By the way, I love your new avatar :-) <NT> DavidWeber New
- Yes, it can. Especially if you're hot and the water is cold. tcookson New
-
- I simply do not believe it. DavidWeber New
-
- <No Subject> jsp New
- Yeah, I'm weighing in again snowwrestler New
-
- yeah... DavidWeber New
-
- Cool. I'm interested to hear more about eVent snowwrestler New
- Impressive, the vapor force is strong with you! <NT> justsurf New
