Does anyone know what the thickness of the "bubble" helmet is? I'm assuming it was vacuum formed since it is poly-carbonate, so would the thickness be somewhat varied throughout the helmet?

Yes, you're right - the polycarbonate varies by about 1mm - thicker on the sides than on the front and back where it is more formed. Min. thickness 4.47mm, average max.at the sides 5.5mm.
