The N-Ferno Black FR Balaclava Face Mask meets two flame-resistant standards - NFPA 70E and NFPA 2112. This winter face mask blocks all the elements: earth, wind, fire and water. Designed with Polartec fleece, which is a grid-construction knit that minimizes fabric mass and maximizes fabric performance for increased warmth and lighter weight, this face mask is a no brainer. The interior is hydrophilic to absorb sweat and transfer it outside, while the exterior disperses moisture for more efficient evaporation. The grid design also creates open air channels for improved breathability. This thermal balaclava works as a ski face mask or a staple on the job to keep you warm and dry so you can focus on the task at hand. The moisture-wicking and breathable fabric makes this balaclava face mask the perfect FR face mask for winter work where FR clothing is required.
