Reflective coating reflects IR and helps dissipate heat. Conditioned to a high of 131˚F (and a low of -23˚F) and then tested to the medium impact rating in the EN166 standard (higher impact speed than ANSI/ISEA Z87.1-2010). Thick visor helps prevent warping, cracking or crazing under tough conditions. Extended length for greater coverage of face and neck; DO NOT use for welding.
