The N-Ferno 6821-ECO Recycled Fleece Balaclava Face Mask is designed with high quality, soft, stretchable 95% recycled polyester and 5% spandex material for warmth when working in the cold. The post-consumer recycled polyester is warm without being bulky and will fit comfortably under a hard hat or helmet. The longer length offers extra coverage for your head and neck and can be tucked into your jacket to seal out the cold. A reflective accent adds visibility at night or in low light.
