Skydivers LOVE their Cookie G3 helmets as well as their GoPro cameras...but combining those two together has been a bit of a gamble in the past as the full-face helmet didn't have any type of cutaway system. And a cutaway system is important at 2,000 feet when that pilot chute just got snagged on your camera mount at the end of a crazy, funneled skydive with a "save yourself" deployment.
Cookie hasn't yet developed a cutaway system for the helmet, so skydivers have resolved to either take the risk, make their own cutaway system, make a mount that is less likely to get snagged or find a mount that cuts away the camera.
The first cutaway system for mounting a GoPro camera came out of Sweden by skydiver Daniel Fagrell. Daniel developed and produced the GrellFAB mount.
