What is a fire suit made of?

A fire suit is typically made of flame-resistant materials such as Nomex, Kevlar, or PBI, which are designed to withstand high temperatures and protect against heat and flames. These materials often have inherent fire-resistant properties and are combined with other fabrics to enhance durability and comfort. Additionally, fire suits may include thermal liners and moisture barriers to provide further protection and comfort for the wearer in extreme conditions.
