Details
Ultra low-profile design. Full-brim protection. Legendary Cairns performance.
The Cairns 660C Metro Structural Fire Helmet combines traditional full-brim protection with an ultra low-profile design that improves balance, mobility, and comfort on the fireground. Built with MSA Cairns’ proven DuraGlas® fiberglass composite shell, the 660C Metro delivers exceptional durability, impact protection, and thermal resistance—making it one of the most trusted structural helmets in the fire service.
Color is molded directly through the fiberglass composite shell to help minimize the appearance of chips, scratches, and wear, allowing the helmet to maintain a professional appearance throughout years of service.
Designed to perform in the most demanding fireground conditions, the 660C Metro features rugged, high-temperature components that maintain performance under extreme heat and operational stress. Its full-brim design offers enhanced water runoff and debris protection while maintaining the low-profile fit firefighters rely on during interior and exterior operations.
