FWIW, I wore my NRS eVent Mission drysuit on Saturday when the air temp was probably too warm for a drysuit with a poly shirt and poly union suit underneath. After two hours of steady paddling I felt warm, but not hot. When I took off the drysuit, the union suit was only slightly moist except for the area covered by the tight fitting spray skirt tunnel which was drenched from perspiration. The fabric, therefore, seems to live up to the claims of superior breathability. I can't speak to longevity since I have had it less than a year, however the workmanship, including the seam taping, is first rate. I find the suit to be extremely comfortable, including the neck seal (unlike my Kokatat Rogue drytop). As for the latex boots, at first I didn't like them, but then found some Lycra drysuit suit socks made by Gill which make it easy to put on neoprene boots. Now I prefer the latex to the breathable fabric boots on my other suit because it doesn't bunch up. The only knock on the suit is that it is not made in the US.
