Prepare for the challenges of the racetrack with K1's Challenger 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.
