Underwear Bottom White Medium SFI-1

The Underwear Bottom White Medium SFI-1 from PYROTECT is an essential base layer for serious motorsports competitors and high-performance drivers who demand the highest safety standards during racing operations. This garment functions as a critical component of a complete fire-resistant racing suit system, designed to be worn as an inner layer beneath your primary racing suit to maximize thermal protection in the event of an engine fire or fuel system failure. Whether you're competing in circuit racing, drag racing, or high-speed performance driving, this SFI-1 rated underwear provides the fire-resistant coverage that sanctioning bodies require and that safety-conscious drivers demand.

PYROTECT's Underwear Bottom in white is constructed from specialized fire-resistant materials engineered to meet SFI Foundation specifications, which establish strict performance standards for thermal and flame protection in motorsports applications. The medium sizing accommodates a range of driver builds while maintaining a close, non-restrictive fit that won't bunch or shift during intense driving sessions. The lightweight construction—just 0.63 pounds—ensures minimal bulk and allows for seamless integration under your race suit without adding unnecessary weight or compromising mobility in the cockpit. The white color option provides excellent visibility for wear and maintenance purposes while reflecting heat to help maintain comfortable core body temperature during extended track sessions.

Professional drivers, amateur racers, and automotive enthusiasts who take safety seriously will appreciate how this PYROTECT base layer integrates into a comprehensive protective system. The medium size makes this ideal for drivers of average to slightly larger builds seeking a snug, reliable fit that won't interfere with seat harnesses or pedal operation. Installation is straightforward—simply wear as an undergarment beneath your racing suit before every event—and maintenance is easy with standard washing protocols. This garment works in conjunction with SFI-rated race suits and is particularly valued in closed-cockpit environments where heat management and fire protection are paramount concerns for competitive motorsports participation.
