Abstract: A head and neck protection system includes a head protector, a shoulder protector, and a neck guard for protecting an athlete from injury. The neck guard detachably connects between the head protector and the shoulder protector and includes a collar. The collar has a first edge and a second edge spaced apart from the first edge and longer than the first edge. The first and second edges include fasteners for detachably coupling the collar between the head protector and the shoulder protector. The collar has a perimeter that flares radially outwardly as the collar extends from the head protector to the shoulder protector. The collar interconnects the head protector with the shoulder protector to form a restraint that limits displacement of the head protector relative to the shoulder protector.
