I have an eVent dry top and I am still damp in it as well. The upper torso just does not get to breathe very well with the spray skirt tunnel and the PFD (oops - Life Preserver if I got that right) covering the drysuit fabric.
I also do not like latex socks that NRS eVent suits have. I have enough problems with the latex that I have deteriorating. I surely do not want ankle seals either with wet cold feet.
I am not just following the Gore-Tex party line as I did buy the eVent dry top. I too wish to see how they hold up, but not on my dime. I really hate being on the bleeding edge of technology.
