I agree with a few of the fellahs up above. The expensive stuff is just that, expensive stuff. I have non breathable raingear and it works fine, was also $100.00 less than the breathable stuff.
Luckily, I have uniforms in the locker room at work so I don't have to wory about the sweat factor. I perfer being wet from body-tempurature-regulating-sweat than from hypothermea-inducing-cold-rain.
