The MSA Cairns Shell Release System (SRS), offered in our most popular fire helmets, protects from impact and heat—even when your helmet is dislodged from your head. With the SRS, if your helmet comes off due to extenuating circumstances—such as a fall through a door or roof, the impact cap is designed to separate from the helmet shell, but remain on your head.

North America’s first (and still the best) NFPA 1971 and ANSI/ISEA Z87.1 impact-rated, integral visor. The Defender Visor was designed with firefighters in mind: stowing away when not in use, deployed with gloved hands, and easily replaced. Replacement of the lens does not require special tools or disassembly of the helmet. All of these benefits make the Defender Visor the best-selling firefighting eye protection in the market.

In 2018, MSA Cairns led the industry by offering removable and replaceable soft goods for all structural firefighting helmets, including soft good kits for easy cleaning.

We back up that claim with a 10-year lifetime warranty that the product will be be free from defects in materials and/or faulty workmanship. When you factor in the quality, ease of maintenance, and unique safety features found ONLY in MSA Cairns Helmets, it’s easy to see why firefighters are fiercely loyal to the MSA Cairns brand.
