Pant Challenger Black 5-XS SFI3.2A/1

The K1 RACEGEAR Pant Challenger Black 5-XS SFI 3.2A/1 is a single-layer, fire-retardant racing pant engineered for drivers who demand proven fire protection without sacrificing mobility. Built from fire-retardant cotton and certified to the SFI 3.2A/1 standard, this driving pant delivers the thermal and ignition resistance required in sanctioned motorsports environments while maintaining the comfort and fit needed for extended track sessions or closed-course driving events.

The SFI 3.2A/1 certification indicates compliance with strict flammability standards recognized across professional racing venues, ensuring the garment resists ignition and flame propagation in high-temperature scenarios. The single-layer construction keeps weight minimal—just 1.22 lbs—while the fire-retardant cotton composition provides inherent thermal protection without heavy laminates. The 5X-Small sizing accommodates drivers requiring a precise, tailored fit that prevents bunching at pedals and maintains unrestricted leg movement during acceleration, braking, and cornering maneuvers.

Drivers who prioritize compliance with tech inspection requirements and seek lightweight, unrestricted movement will find this pant reliable for session after session. The black colorway integrates seamlessly with racing suits and driving suits from most manufacturers.
