This adult-sized RaceQuip® SFI 3.3 rated single layer underwear hood also called a balaclava or head sock is 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 moisture 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 hood is a one-layer, one-eye port design with a long bib in the front. Exceeds SFI 3.3 rating and is available in black.
