The Sparco RW-7 Racing Undershirt is a professional-grade base layer engineered to balance elite fire protection with advanced thermal management. Crafted from a specialized blend of soft, stretchable Nomex fibers, this slim-fitting undershirt is treated with Sparco’s innovative X-Cool technology, which actively draws heat away from the skin to keep drivers cool under pressure. The design features seamless sides and raglan-style sleeves to eliminate pressure points and maximize mobility, ensuring a comfortable, distraction-free fit beneath any racing suit.
