Abstract: The invention is a chin stabilizer system for a full-face helmet, such as a motorcycle helmet or the like. It includes a flexible material having a generally triangular configuration with snap fittings at each point of the triangle. The snap fittings connect the flexible material to the helmet, underneath the chin. One snap fitting connects the material near the chin, while the other two connect the material to the helmet on opposite sides, near the wearer's jaw. The flexible material restrains the helmet from riding up over the face of the wearer.
