The N-Ferno 6821-ECO Recycled Fleece Balaclava Face Mask is designed with high quality, soft, stretchable recycled polyester and 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. One size fits most and can be worn alone or under hard hats, ski helmets or other head protection. This is the perfect warm face mask for those who work in construction, freight/baggage, drilling/mining, oil/gas refining, iron/steel, delivery/service, landscaping/grounds, warehousing and for those who work in refrigerated areas. Can also be worn as a ski face mask or worn hunting, climbing, running, cycling, boating, skating or other outdoor sports. This balaclava is made from recycled polyester, which is produced by converting waste bottles into polyester yarn through chip making and spinning. The yarn is then knitted and dyed and sent to the manufacturer for proper balaclava cutting and sewing. Each balaclava is equivalent to approximately 7, 16.9 oz /500mL plastic water bottles.

From reducing waste to incorporating sustainable materials and practices whenever and whenever possible, our Blue Marble mission honors the need to do better without compromising quality or performance, ensuring every worker heads home safe, sound and happy when the whistle blows.
