An industrial protective helmet has a rigid outer shell extending upon a surface region of a wearer's head, including temple and skull base regions, a liner of rigid foam fixedly attached to an inner surface of the rigid shell, and one or more selectively-positioned, fit-adjustment elements of compressible foam material engaged upon an exposed surface of the liner with an opposite surface positioned for cushioning engagement with the wearer's head. The helmet may also include one or more of a resilient strap extending about the rear of the head, an adjustable transparent peak, a removable sweat band, a chin strap and/or a fabric cover.
