Reflective Coating: The outer layer is coated with aluminum or an aluminized material that reflects radiant heat away from the body. This coating helps prevent burns and heat stress.Durable Fabric: The aluminized layer is often made from materials like woven fiberglass or other high-temperature-resistant fabrics that can withstand intense heat and flames.
Inner Layer:
Insulating Material: The inner layer provides thermal insulation and comfort. Common materials include heat-resistant fibers such as aramid (e.g., Kevlar) or high-density foam. This layer helps to keep the wearer’s body temperature regulated and reduces the risk of heat-related injuries.
