iyossarian -- take a look around a hardware store or big box store for a replacement face shield like you would use in a shop. The plastic is fairly strong and already curved. I'm guessing with just a little cutting and maybe some velocro you could attach it to your helmet. That was my plan before my wife bought me some pretty cool goggles. The goggles fog sometimes, but I'm still refining my technique on their use. I haven't yet found the cat crap stuff to try it out.
