Racing underwear is a layer of flame-retardant clothing worn underneath the racing suit. Its primary function is to provide an additional layer of protection against heat and flames in the event of a fire. Made from fire-resistant materials like Nomex, Lenzing FR, or other aramid fibers, racing underwear is designed to resist combustion, prevent heat transfer to the skin, and minimize burn injuries.

Key Benefits of Racing Underwear:

  • Fire Resistance: Provides a critical barrier against heat and flames.
  • Thermal Insulation: Helps to keep the driver cooler by wicking away moisture.
  • Comfort: Designed to be lightweight and breathable, enhancing comfort during long races.
  • Regulatory Compliance: Mandatory in many types of motorsports under FIA regulations.
