Fortunately, I do not know yet, but my guess is that they are not going to be so great because they have vents on the front side. Time will tell. They never fog up which is nice and the line of vision is awesome, They are super dark so no good for night either. They come in a clear lens version with a mirror coating that would be good for night use. I was just wearing them for kicks at first but I tried to switch back to my regular riding glasses and realized how much the padded sunglasses suck. These goggles are Awesome with a capital A. I don't care how they look or what anybody else thinks, they are great! Of all the years I have been riding , I have never really tried goggles before and I now believe that any of them would be superiour to padded sunglasses.
Oh, and Charley, You had better not spray no Raid on me!
