ergodyne N-Ferno 6802Z Zippered Trapper Hat, 3M Thinsulate/Nylon, Large/X-Large, Black

The N-Ferno 6802Z Zippered Trapper Hat provides warmth from extreme cold, as well as the option for lightweight protection from bumps, scrapes, bruises and other minor head injuries. Wear alone as a classic aviator hat or open the top zippered compartment to add the 8945 Universal Bump Cap Insert (sold separately) for work in cramped spaces. This trapper hat features a windproof and water-resistant oxford nylon shell lined with 40 grams of 3M Thinsulate Insulation for comfortable warmth in extreme conditions. A water-resistant crown lining prevents sweat or moisture from being absorbed into the lining to keep you dry and warm. Ear flaps can be buttoned up for improved hearing through the small ear holes or down for increased warmth. A chin strap with YKK buckle makes for an adjustable fit, and a reflective accent on the back keeps workers safe and seen.
