A helmet contains a convex, hard outer shell, a concave, impact-dissipating inner layer, a shield, and a shield cover. The concave, impact-dissipating inner layer is fitted to the convex, hard outer shell. The concave, impact-dissipating inner layer contains a front portion having a shield indentation, a back portion opposite the front portion, a top portion joining the front portion and the back portion, a right side portion joining the front portion, the back portion, and the top portion, and a left side portion joining the front portion, the back portion, and the top portion. The left side portion is opposite the right side portion. The shield is pivotably attached to the helmet via a fulcrum and pivots about the fulcrum. The shield also partially occludes the shield indentation. The shield cover is fixably attached to the helmet and at least partially occludes the front portion. The shield cover also at least partially occludes the shield. |
