Undershirt Precision Black X-Large

The Undershirt Precision Black X-Large from K1 RACEGEAR is a high-performance short-sleeve undershirt designed for drivers, racers, and tactical professionals who need reliable heat protection and comfort. This undershirt serves as a critical base layer beneath fire-resistant racing suits, flight suits, or tactical gear, making it suitable for high-temperature environments.

Constructed from Nomex material, the Undershirt Precision Black X-Large offers inherent flame resistance without chemical treatments, ensuring durability through repeated wear and washing. Nomex fibers are known for their ability to resist combustion and char, providing a protective barrier against external heat sources. The high collar design maximizes neck and shoulder coverage while maintaining mobility.

This X-Large sizing is ideal for drivers, crew chiefs, aviators, and tactical operators who require consistent and reliable base-layer protection during extended wear. The black colorway resists staining and discoloration, making it a practical choice for professional motorsports and tactical environments.
