<p>The N-Ferno Balaclava Face Mask is designed with high-quality, soft, stretchable fleece for warmth when working in the cold. Heat-trapping fleece is warm without being bulky and will fit comfortably under a hard hat or helmet. Soft fleece traps body heat for warmth when working in the cold. High-quality, thermal fleece promotes warmth in mild-to-extreme conditions. Long length adds extra coverage for your head and neck and can be tucked into your jacket to seal out the cold. High-visibility lime color stands out. Reflective accents add visibility at night or in low-light conditions. 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.</p>
