Somewhere between the open-face helmet and the full-face helmet is the modular motorcycle helmet -- also called a flip-up helmet, flip-face helmet, system helmet and other names. This style helmet permits the wearer to raise the facial section out of the way, allowing him to eat, drink, smoke or simply remove a barrier to conversation without going through the rigmarole of unfastening and removing his helmet and then replacing it and reattaching the strap.
