SFI 3.3 FR Underwear Top Black MED

The ALLSTAR PERFORMANCE SFI 3.3 FR Underwear Top in Black, Medium is a long-sleeve, high-collar fire-retardant base layer engineered for motorsports competitors and racing professionals who require certified thermal protection in the cockpit. This fire-retardant underwear top meets SFI 3.3 standards, the industry benchmark for driver safety gear in racing environments where heat and flame exposure present genuine hazards.

Constructed from a fire-retardant blend fabric, this base layer provides thermal insulation and burn protection without the bulk of heavy outer suits. The long-sleeve design with high collar extends coverage to the neck, a critical area in racing safety protocols. SFI 3.3 certification means this garment has undergone rigorous testing for flame resistance and thermal protection, ensuring it meets federally recognized motorsports safety standards. The medium sizing is cut to fit underneath racing suits and driving gear, allowing for layering without compromising fit or mobility during high-performance driving.

This underwear top is essential equipment for circle track racers, drag racing competitors, road course drivers, and any motorsports participant whose governing body or sanction requires SFI-certified fire-retardant base layers. Many racing organizations mandate such protection as a condition of on-track participation. The black colorway integrates seamlessly under racing suits and remains practical for repeated washing and competition use.

Racing regulations across major sanctions—NHRA, NASCAR, ARCA, and various road racing bodies—recognize SFI 3.3 as the baseline fire-retardant standard for driver underwear. This ALLSTAR offering delivers verified protection at an accessible price point for weekend competitors and professional drivers alike.
