We highly recommend wearing an extra layer of fire protection under your race suit in the form of SFI-Rated Underwear. These garments carry the SFI` 3.3 Rating and are available in balaclavas, shirts, sports bras, and pants. Each layer of fire retardant material worn increases the overall protection provided and the^ length of time available to escape from a fire.

Many organizations that require an SFI-5 rated racing suit will allow an SFI-1 rated suit to pass tech inspection if SFI rated underwear is worn underneath.
