Ergodyne - EGO16832 The N-Ferno Balaclava Face Mask is made with lightweight, stretchable spandex and features a three-panel design for all-day comfort, plus full head and facial protection. Polyester/spandex blend dries quickly and wicks moisture away from the skin. Three-panel design allows freedom of movement in any direction. Long length adds extra coverage for your head and neck and can be tucked into your jacket to seal out the cold. Reflective accents add visibility at night or in low-light conditions. With stretchable material, one size fits most and can be worn alone or under hard hats, ski helmets or other head protection. This face mask is perfect for construction, freight/baggage, drilling/mining, oil/gas refining, iron/steel work, delivery/service, landscaping/grounds, cold storage/warehousing and material handling.
