The Ergodyne N-Ferno 6802 Classic Trapper Hat is made with durable windproof and water-resistant nylon to keep you warm and dry in even the most extreme temperatures. Wear this trapper hat with the ear flaps up or down to completely cover your ears. Even the worst blizzards don't stand a chance against this aviator hat. Lined with 60 grams of 3M insulation for comfortable warmth in the cold, with water-resistant crown lining prevents sweat or moisture from being absorbed into the lining, keeping you warmer. The ear flaps feature smaller ear holes on each side for improved hearing when wearing the flaps up. Button the smaller flaps down for even more warmth.
