A tough, high-temperature thermoplastic shell resists chipping and cracking and a low-ride helmet design creates a low-profile for superior clearance and maneuverability. The high-tech thermal impact cap provides increased heat and impact protection. Features non-corroding, high-temperature, glass-filled polymer faceshield/goggle hardware and faceshield wing protectors for extra faceshield reinforcement. The ultra high-temperature (TPR) edge trim will not melt or drip. A Nomex chinstrap with one-hand quick release buckle and postman slide allows quick and easy adjustment. The choice of Nomex or Pbi/Kevlar earlap offers increased neck/ear coverage and protection. The exclusive SCBA interface front headband adjustment matches the fit of any SCBA facepiece and the three-position, rear-ratchet height adjustment ensures a secure and comfortable fit for all head sizes between 5-5/8 and 7-5/8 inches. A choice of flannel or leather cushion liners, removable for washing and upgrading, provides greater ease and comfort. The larger diameter helmet hanger fits on larger hooks and racks. Protect against fireground damage with Cairns five-year shell replacement/warranty.
