MTBR includes the Lazer Revolution FF helmet in their run down of new Enduro-ready helmets with removable chin bars:
Lazer also developed a safety-enhancing accessory mount that is made from a flexible plastic, which decreases the potential for a snag during an impact. If for instance your POV camera does clip an object, the mount is designed to let it easily break away with damaging the unit. Lazer also drop tested the helmet with an accessory mounted to assure that it would not allow an intrusion into the outer shell.
