The N-Ferno 6802ZI Zippered Trapper Hat with Bump Cap Insert provides warmth from extreme cold, as well as 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 (included) 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. Available in two sizes (S/M or L/XL) to fit a variety of head sizes. Included with the trapper hat is a Skullerz 8945 Universal Bump Cap Insert. This impact-resistant shell is made of lightweight durable polypropylene and is designed with maximum ventilation for breathable airflow that doesn't compromise protection. An interior foam pad reduces impact but does not absorb odors for fresh all-day wear. Bump caps are typically worn in spaces where worker-generated impact head protection is needed, like low ceilings, beams, low pipes and other bump hazards. Size: Large. Color: Black. Gender: male.
