Let the winter winds blow, you're covered. Our ultra-warm aviator hat protects you with a melton wool shell, a generously wide trim of thick shearling, and a quilted satin lining. Fasten those wide shearling earflaps up or down with the leather straps. And when the temperatures fall, unsnap the front shearling cuff. Shell: wool 80% /nylon 20%. Made in Canada.
