Description
The Simpson Racing CarbonX® Ultimate™ Underwear in Black (Medium) is engineered to deliver premium thermal protection, comfort, and performance for motorsport drivers. Built from a patented double jersey interlock knit blend of high-performance fibers, this advanced base layer provides exceptional fire-resistant properties while maintaining lightweight flexibility and breathability.
