Need some serious fortification from the winter weather? Just slip on this intrepid trapper cap. The exterior is indomitable Fire Hose HD — a high-tech wonder fabric that’s 4x more abrasion-resistant than standard cotton canvas. Repels moisture, too, so you can waltz through squalls in cozy, dry comfort. Inside, there’s a soft, warm microfleece lining. In between is heat-holding polyfill. Earflaps fold down to prevent Jack Frost from nipping at your lobes.
