I have been looking for one for a while. The BMX helmets have the wind/sun shade on the front. Remove it and you have three holes pre drilled and ready for mounting cameras. One on each side, and a center on top. They also provide a little more comfort than just a regular helmet for the poor guy who will be wearing it. $5.00 at a second hand store, not too bad to hold a couple of GoPro Heros.
