Achieve certified safety at an unbeatable price with the K1 Challenger SFI Racing Suit Pants. These single-layer pants meet stringent SFI 3.2A/1 certification standards, offering superb protection for entry-level racers, pit crews, mechanics, and race officials. Manufactured from the highest-quality treated PROBAN® FR Cotton, they are the logical choice for any racing series that does not require the use of more expensive Nomex® or other inherently flame-resistant aramid fabrics.

Ideal for a variety of racing classes, the Challenger pants are perfect for dirt track and oval racing — including Midgets, Sprint Cars, Legends, and Bandoleros — as well as sports car classes like SCCA Solo and ProSolo. Sold separately, they can be paired with the matching K1 Challenger Jacket to create a versatile two-piece suit. The Challenger set is also available as a one-piece suit.

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.
