The helmets with a face shield get dust on the back of the shield, inside the helmet. You can wipe off the outside with your gloved hand but not the inside. Plus wiping scratches the shield. Goggle lenses are cheaper than face shields to replace after scratching them up. My 2 cents.
I started with one of those 1970's full face helmets with the blue sparkle of the time. Hand me down used piece of junk. You were lucky to have a visor back then. Now I get a new O'Neal helmet and matching gear from Rocky mountain every couple years. I have a blue, red and green set for color coordinating my 3 bikes.
This is the helmet my wife bought me last summer. It is extremely light and comfortable. I love it.
