Engineered to be super tough yet lightweight, this structural fire helmet is constructed from Thermoglas® material using a thermoset fire-retardant resin. The molded nylon inner liner features a polyurethane foam thermal barrier to deliver both impact protection and resistance to internal heat rise. A washable Nomex® outer shell backed with three layers of FR cotton flannel protects the ears and neck. This helmet is also equipped with the innovative ReTrak Visor that provides eye protection, slides up to stow inside the helmet when not in use, and meets NFPA 1971/ ANSI/ISEA Z87.1+. The ReTrak pivots away from the face as it deploys to prevent interference with eyewear, accommodates a wide variety of face shapes, features a comfort nosepiece, and offers simple lens removal for decontamination and maintenance. The helmet's U-Fit headband system featuring a 6-point nylon crown strap and crown pad provides 36 different adjustment settings to ensure a comfortable fit. The Nomex® chinstrap features a one-hand quick-release buckle and postman slide for fast removal and adjustment. Meets and exceeds NFPA 1971, Standard on Protective Ensemble for Structural Firefighting and Proximity Firefighting, Pertaining to Structural Fire Helmets.
