The N-Ferno 6893ZI Zippered Balaclava Face Mask with Bump Cap Insert provides warmth for extreme cold, as well as lightweight protection from bumps, scrapes, bruises and other minor head injuries. Wear alone as a balaclava face mask or open the top zippered compartment to add the Skullerz 8945 Universal Bump Cap Insert (included) for work in cramped spaces. This winter liner is made of stretchable polyester fleece for a comfortable snug fit that traps heat, plus a long length design that easily tucks into jackets for wind protection in extreme cold. A reflective accent keeps workers safe and seen. When worn without the bump cap insert, it makes for a great thermal layer under hard hats or helmets. Included with this full face mask is a Skullerz 8945 Universal Bump Cap Insert. This impact-resistant shell is made of lightweight durable polypropylene and is designed with maximum ventilation. An interior foam pad reduces impact but does not absorb odors for fresh all-day wear. Size: One Size Fits Most. Color: Black. Gender: male. Age Group: adult.
