CMC Fire Escape HarnessFEATURES IMPROVED! Designed to be worn during fire ground operations, the Fire Escape Harness uses Kevlar brand fiber web for high heat and flame resistance and can be worn over bunker pants without compromising firefighter safety. If done with care, the harness can be left on over the pants when they are stored, so it can be donned simultaneously. The new, improved design is one size fits most.
