If using a single layer sfi 3 2 a1 or 3 2 a3 suit the driver must also wear fire retardant sfi or fia certified undergarments. That is why northstar motorsports only sells multi layer suits made from nomex and we highly recommend either a three layer suit with an fia 8856 2000 rating or a two or three layer suit with an sfi 3 2a 5 rating for all types of racing.
