the Voodoos are really small, not as small as the Toasters, if you like the Toasters, my friend loves hers and I did not like the look of them. I wear the Giro and they work great with it, altough I do not like the helmet that much and am looking for a new one. I have heard that if you put the straps on the inside of your glasses that takes the pressure off, but it feels strange to me.
