Prepare for the challenges of the racetrack with K1’s Challenger SFI Racing Suit! Constructed from lightweight, single-layer, fire-retardant cotton, the Challenger suit delivers both fire resistance and comfort at an affordable price. Featuring an SFI 3.2A/1 rating and 360-degree shoulder gussets for unrestricted movement, the versatility of this suit is what sets it apart.

Available as a one-piece driving suit or as a jacket and pants set (each piece is sold separately), you can be sure K1 has a combination that will cater to your specific racing needs. The boot cut legs offer a stylish and functional design that fits over racing boots with ease. Whether you're a professional racer or an amateur enthusiast, the Challenger Suit is your ticket to performance and safety on the racetrack. Face the challenges with confidence!

Please note: Unlike Nomex® and other aramid materials that are inherently flame-resistant, FR cotton is treated with a flame-retardant chemical that can lose efficacy over the course of the garment’s lifetime.

  • Ultra-Lightweight Breathable Fire Resistant Cotton Material

Material (Proban® Cotton):

FR Cotton, including its branded counterpart Proban®, stands as a reliable flame-resistant material, providing consistent fire protection. While FR Cotton is treated with a flame retardant chemical for initial resistance, it's important to note that this treatment may diminish over time through washing.

Certification: SFI 3.2A/1

Generally single layer suits with a Thermal Protection value of six.  Suits rated to 3.2A/1 are tested for up to 6 seconds in simulated lab fires, offering approximately 3 seconds of fire protection against second-degree burns.

Machine wash on gentle cycle in mild-detergent on cold or warm cycle. Do not exceed 30 degrees (Celsius, 86 degrees Fahrenheit). Close all zippers, and secure all hook and loop closures (if applicable) and turn garment inside out to avoid damage while washing. Never use detergents containing bleach! Tumble dry on low heat for ten minutes then hang dry.
