PYROTECT's ultra thin INNER WEAR is designed for use with any driving suit, and is as soft as cashmere and as absorbent as cotton! Talk about comfort... No more scratchy, irritating Nomex next to the skin and the absorbency keeps you cool and dry. It is SFI rated for use as underwear, but is also designed so it can be worn under Nomex underwear for added TPP protection and crew uniforms for fire protection.

RaceQuip SFI 3.3 rated long underwear bottoms 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 pants bottom is a long john design with cuffs at the ankles and exceeds the SFI 3.3 rating. Available in black in sizes X-Small - 5XL - remember that racing underwear is designed and built to fit snugly.
