What is the primary purpose of the moisture layer in firefighter gear?

The primary purpose of the moisture layer in firefighter gear is to facilitate thermal regulation. This layer plays a critical role in managing the heat and moisture that firefighters encounter in high-temperature environments. It allows sweat and moisture generated by the body to escape while preventing external moisture from penetrating the gear. This function is essential for maintaining the wearer's core temperature and comfort, which can significantly affect performance and safety during firefighting efforts.

While protecting against steam burns is important, it is not the main function of the moisture layer. Instead, the overall design of firefighter gear incorporates multiple layers, each serving distinct purposes such as insulation, moisture management, and protection from thermal hazards. The moisture layer's ability to regulate temperature also contributes to the effectiveness of insulation, ensuring that firefighters can operate safely and efficiently for extended periods.
