BarriAire™ Gold Hood Critical Coverage (STK) 3979471-1
Particulate coverage from base of the neck and around entire head except for Sure‑Fit™ panel at crown. All critical areas of particualte penetration as identified by NFPA have particulate barrier. UL Classified to NFPA 1971 Standard on Protective Ensembles for Structural Fire Fighting and Proximity Fire Fighting – Current Edition. Certification to the NFPA 1971, 2018 Edition Option for Particulate Protection – Current Edition. EN13911: 2017 Certification Pending.
Fabric Description:Quilted composite durable water resistant finish on exterior layer of jersey knit with Nomex® Nano Flex particulate barrier between the inside layer of jersey knit. Averages 95%‑98% particulate filtration efficiency that actually improves with repeated launderings.
