Cookie GoPro Roller Mount Full Face Kit
This Kit includes all you need to enable you to mount your G3 Roller Mount to a G4 helmet (or other brands of full face helmets).
The Kit include 2 spacers that allow the original G3 mount to adapt to the unique shape of the G4 Helmet. The spacers come in 2 G4 sizes (YM-L and XL-XXL). Note. You'll receive both spacers but will only require 1, depending on the helmet.
