Sparco Mens Underwear (Bottom)(Black, Medium/Large), 1 Pack

Sparco shield rw-9 are among the most breathable, comfortable, and safe Nomex undergarments on the market. When developing this line, Sparco studied multiple drivers sitting positions ensuring the most flexibility and comfort possible. Sparco shield rw-9 has seamless construction with ultra soft stretchable material. There are two different materials woven in key areas, thin stretch Nomex for mobility and comfort as well as double perforated Nomex for maximum breathability and ultimate comfort. For more added comfort the shield rw-9 has minimal seems that are stitched flat with thin specialized thread. All pieces of the shield rw-9 line are treated with Sparco x-cool silver which draws optimal heat from the surface of the body to cool the driver. Along with cooling the driver, x-cool silver treatment has an anti-bacterial effect.
