Simpson CarbonX Ultimate underwear bottoms are made from double jersey interlock knit comprised of a patented blend of high performance fibers—and have extraordinary thermal protective properties. Nomex or CarbonX underwear, when worn beneath a racing suit, dramatically improves Thermal Protection Performance (TPP) in the case of an accident involving fire. SFI 3.3 approved, CarbonX Ultimate under garments are inherently flame-resistant, and will not burn, melt, or ignite when subjected to direct flame. Add an extra layer of racing protection with Simpson Racing's CarbonX Ultimate under garments.

• SFI 3.3 approved, includes SFI tag
• Designed to deliver the ultimate in base layer thermal protection
• TPP rating of 13 cal/cm2 and zero seconds after flame
