This Thermal Trapper Hat features a zippered compartment on the top to fit a removable Bump Cap Insert to provide both warmth from extreme cold and head protection. Wear alone as a classic aviator hat or combine with the lightweight Skullerz 8945 Universal Bump Cap to protect your cranium from bumps, scrapes, bruises and other minor head injuries.

Made with durable, water-resistant nylon to keep you warm, dry and out of the wind in extreme weather conditions. Wear this good-looking winter hat with the ear flaps up or down to completely cover your ears. Even the worst of blizzards don't stand a chance.
