The K1 Challenger SFI Racing Suit Jacket features an SFI 3.2A/1 rating and is manufactured using the highest quality, treated FR Cotton available on the market. Ideal for entry-level racers, pit crews, race officials, and mechanics participating in series that do not require Nomex® or other aramid fabrics, K1’s Challenger PROBAN® cotton jacket is the logical choice for safety and affordability! The Challenger Jacket is ideal for a variety of racing classes, including dirt track and oval racing leagues such as Midgets, Quarter Midgets, Bandoleros, Sprint Cars, Legends, and Thunder Roadsters, as well as sports car racing classes like SCCA Solo and ProSolo. Also available in a one-piece race suit, the Challenger Jacket is sold individually.

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.
