Underwear Bottom Black Medium SFI-1

The Underwear Bottom Black Medium SFI-1 by PYROTECT is a specialized base layer garment engineered for high-heat and motorsports environments where fire-resistant protection is non-negotiable. Designed for racing drivers, pit crew, and motorsports professionals, this safety underwear serves as a critical thermal barrier beneath racing suits and protective gear. SFI-1 certification indicates compliance with the Society of Automotive Engineers' stringent flammability standards, making it essential equipment for anyone operating in sanctioned racing events or high-risk thermal environments.

Constructed from fire-resistant materials meeting SFI Foundation specifications, the Underwear Bottom Black Medium provides reliable thermal protection and flame resistance without sacrificing comfort during extended wear. The black colorway offers versatile layering capability under any racing suit color, while the medium sizing delivers a snug, secure fit that prevents bunching or shifting during intense driving conditions. The lightweight design—just 1 pound—minimizes bulk and heat retention while maintaining the protective integrity required for motorsports applications where fractions of a second matter and safety cannot be compromised.

This product is ideal for competitive racers, driving enthusiasts, and motorsports teams who require certified flame-resistant apparel for track events and sanctioned competitions. The SFI-1 certification is recognized across major racing sanctioning bodies, including NASCAR, NHRA, and road racing organizations, making it the correct choice for legal compliance at the track. When paired with an SFI-certified racing suit, these underwear bottoms create a multi-layer thermal protection system that meets or exceeds safety regulations while allowing freedom of movement in the cockpit.
