First introduced in 1975, the RaceQuip brand has built a reputation for manufacturing and distributing high-quality auto racing safety equipment. The SFI and FIA-rated auto racing and motorsports safety gear manufactured by RaceQuip is recognized by and designed for use in almost any racing series or sanction.

RaceQuip SFI 3.3 rated socks are knit from a blend of aramid and FRC fabrics to achieve a comfortable fire retardant garment. The properties of this unique fabric structure create a lightweight fabric that performs like Nomex yet is much more cost-effective. The Fire Retardant Cotton (FRC) component of the fabric promotes a soft and supple lightweight feel. Since its hypoallergenic, it wont irritate your skin like some other materials tend to do. This proprietary fabric blend is also superior at wicking away moisture from the skin and dries quickly. All RaceQuip fire retardant underwear garments are machine washable and retain their shape well. Exceeds SFI 3.3 rating and available in black sizes XX-Small - 2XL - remember that racing underwear is designed and built to fit snugly so go up one size if you want it more loose-fitting.
