Abstract: A helmet that both protects the user against injury during a fight and indicates through the release of stage blood that a blow to the head has been struck sufficient to cause a concussion or bloody head injury if the helmet were not present. The helmet includes an inner helmet and outer helmet. The inner helmet is similar in construction to helmets presently used in sports such as football, hockey and bicycling preferably with an absorbent layer next to the user's head, an intermediate soft protective layer and a hard plastic outer layer. On top of the inner helmet, an outer helmet is provided with a reservoir or multiple packets of stage blood. For added protection, a visor and neck protector are preferably attached to the helmet.

Abstract: A helmet that both protects the user against injury during a fight and indicates through the cracking of an outer shell and release of stage blood that a blow to the head has been struck sufficient to cause a concussion or bloody head injury to an unprotected head. The helmet includes an inner helmet and outer helmet. The inner helmet is preferably similar in construction to helmets presently used in sports such as football, hockey and bicycling with an absorbent layer next to the user's head, an intermediate soft protective layer and a hard plastic outer layer. On top of the inner helmet, an outer helmet is provided consisting of two plastic shells sandwiching a reservoir of stage blood. For added protection, a visor and neck protector are preferably attached to the helmet.
