RaceQuip SFI 3.3 rated long underwear tops 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 it's hypoallergenic, it won't irritate your skin like some other materials tend to do. This proprietary fabric blend is also superior at wicking away mositure from the skin and dries quickly. Seams are flat sewn and strategically placed to avoid pressure points and promote comfort. All RaceQuip fire retardant underwear garments are machine washable and retain their shape well. This top is a long sleeve design with cuffs at the wrists and a mock turtle neck collar. Exceeds SFI 3.3 rating and is available in black sizes X-Small - 5XL - remember that racing underwear is designed and built to fit snugly.
