Nomex Underwear for Auto Racing

Nomex underwear or underwear constructed from other Fire Retardant materials, are an effective and relatively inexpensive way to add additional protection to your race safety program.
Independent lab testing on nomex or proban type underwear, when worn in conjunction with a nomex or proban race suit, can practically double the effective heat transfer rate.
SFI-1, 3.2A/1 or single layer race suits with the addition of nomex underwear, increases the heat transfer rate from 3 to 6 seconds. SFI-5, 3.2A/5 or multi layer race suits with the addition of nomex underwear increases the heat transfer rate from 9 seconds to 19 seconds. Of course, these numbers are approximates, conducted by the SFI Foundation's lab testing, under certain conditions.
Racers can purchase a fire retardant top and bottom, with an SFI certification tag, for around 100.00. Nomex socks and a nomex head sock or balaclava, are also available for racers concerned with protecting themselves to the fullest.
