The GDM DEMON is a DOT FMVSS-218 certified full face helmet sold as a kit with the GDM HyperSonic Bluetooth 5.0 headset and four face shields (clear, tinted, chrome, iridium). The composite poly-alloy shell has a rear spoiler and five vents at the chin, forehead and rear, and the liner and cheek pads come out for washing. The headset handles calls, music, GPS and a rider-to-rider intercom with another HyperSonic unit at up to 100 meters, rated for up to 12 hours of talk and music and 120 hours standby. It suits riders who want one purchase covering helmet, comms and spare shields; the headset mounts with included hardware rather than coming pre-installed, and the intercom only pairs with GDM HyperSonic headsets, not other brands.
