Matthews HOT Flags are manufactured from a patented, thermal resistant fabric which will allow precise cutting of the light at relatively close distances to large, heat producing HMI or Tungsten fixtures. Matthews HOT Flags will endure a continuous heat of 1800^°F (982^°C). Matthews HOT Flags weigh about half as much as the metal Hi-Temp flags and dissipate heat rapidly, allowing for easier handling and faster tear down of the lighting set up.
