Your race suit is only part of your protection system. The SFI 3.3 Nomex undergarment set — long-sleeve shirt and pants — adds a thermal barrier between your skin and the suit that significantly increases the time before a burn injury would occur in a fire event.

Most serious racing classes that require a fire suit also recommend or require SFI-rated undergarments. Running Nomex underneath your 3.2A suit effectively compounds your protection. It is one of the easiest and least expensive upgrades you can make to your safety system.

Wear under any SFI or FIA-rated race suit. Lightweight and breathable enough to wear for full-day events without added discomfort.
