X2 on what Josh said, I have the half and the wife has a full. Nice in the summer b/c you get just enough air to cool you off but can ride without goggles if you want. A little cool in the winter but not unbearable. And if you get into some mud, you don't have to stop to clean it off. Not enough air flow in the summer with the full windshield for my taste, and even the best polycarbonate gets scratched up and that's a pain. Just get one with the 1 1/2 deflector at the top, you'll love it.
