Thanks for the updated review, Fred. I'm thinking very seriously about getting one of these. Weird question: With so much air blowing through it, do you find that you sweat enough to keep up a steady rate of evaporation? After all, it's the evaporation -- the change of state from water to water vapor -- that cools our skin (it's why we sweat), and if you get too much air flow I'm thinking you might end up getting desiccated on a hot day...

As for getting easily soiled, here's a vendor in Beijing that seems to have the same jacket in black as well as the more attractive silver that you seem to have.



cheers!
