I don't think so. Seriously, you think you're going to ride in the rain and not get wet?

I've run fenders. Get any speed and the water coming off the front wheel is still going to blow forward off the top of the wheel then back in your face. Rear with the right rack (I use Topeak MTX which are essentially closed at the top) isn't going to throw the water up your back, and beyond that the rest is rain - you're still going to get wet. Sure, I'll give you that you may not get as dirty, but once you're wet you can only get so wet..
