FIA long underwear pants

FIA long underwear pants are part of the fire-resistant base layer worn under a racing suit in motorsport. They are designed to provide additional protection for the legs and lower body in the event of fire or high heat, while remaining comfortable during longer periods of driving.

Unlike regular long underwear, FIA long underwear pants are made from materials designed for motorsport and high safety requirements. They are typically worn together with an FIA undershirt, balaclava, socks, gloves, shoes, helmet and racing suit as part of the complete safety equipment.

A good fit is important, as the underwear should fit close to the body without causing discomfort under the racing suit. Breathable materials, flexibility and flat seams can make a significant difference to comfort, especially during longer stints on the track, in rallying or racing.

FIA long underwear pants are used in race cars, rally cars, track cars and other motorsport disciplines where personal safety equipment is necessary or required by regulations. When choosing FIA long underwear pants, it is important to check which FIA standard each model is approved to. Newer models are typically approved to FIA 8856-2018, while older models may be approved to FIA 8856-2000. Requirements may vary between different racing series and championships, and FIA 8856-2000 is being phased out in favour of the newer standard. Therefore, always check the applicable regulations for the motorsport discipline in which you participate.

Whether you compete in racing, rallying, track days or other forms of motorsport, FIA long underwear pants are an important layer under the racing suit and an ideal choice when safety, comfort and the correct equipment need to go hand in hand.
