Fire proximity suit

A fire proximity suit (also, silvers or silver bunker suit) is a suit designed to protect a firefighter from high temperatures, especially near fires of extreme temperature such as aircraft fires.

Fire proximity suits first appeared during the 1930s, and were originally made of asbestos fabric (hence also known as the asbestos suit). Today they are manufactured from vacuum-deposited aluminized materials that reflect the high radiant loads produced by the fire.
