In a few days, I'll have my Endura eVent "overtrousers" (as they are referred to in the UK). I'm hoping for a good 35F rainy day in the near future to put them to the test. I'll keep everyone informed on how they perform. I already have a Gill Prospeed eVent jacket which is completely waterproof and breathes enough that I can wear it in 60+ degree weather and not overheat. Anything above that and I just get wet.
