Stay warm and fully protected on demanding winter job sites with the Ganka 70-WH-17 Winter Hard Hat Liner. Engineered specifically for professional outdoor trade environments, this multi-piece liner easily integrates beneath standard hard hats to lock out freezing drafts and sub-zero temperatures. Built with a rugged, wind-resistant 100% cotton shell and insulated with a soft, heat-trapping polyester lining, it provides superior thermal retention without adding bulk. The extended neck drape shields the collar line, while the integrated, adjustable face mask offers critical protection for the nose and cheeks when conditions worsen.
