Hat is made with durable windproof and water-resistant nylon to keep you warm and dry in even the most extreme temperatures. Wear it 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 Thinsulate Insulation for comfortable warmth in the cold. The water-resistant crown lining prevents sweat or moisture from being absorbed into the lining, keeping you warmer.
