K1 RaceGear Premier Underwear Bottoms - SFI 3.3

K1 RaceGear Underwear Bottoms are perfect if you race sports cars, open-wheel cars, stock cars or any other type of race car.  These underwear bottoms are SFI Certified and made from fire-resistant Nomex.  Even if your sanctioning body does not require them, it is an important investment to help ensure your safety in the event of a fire.  The benefits go beyond safety, however; Nomex clothing also helps to keep you comfortable on the track, by wicking moisture away from the body and allowing circulation. 

Featuring soft Nomex material for comfort and contrast cross-stitching for style and durability, K1 Premier Nomex fire-resistant pants are practical, comfortable, and effective. They are also designed to meet stringent safety standards.  This base layer is SFI 3.3 certified.
