The Sparco Shield Pro RW10 line of undergarments is the lightest and most breathable on the market that is homologated to the new FIA 8856-2018 standard. The Shield Pro features a seamless construction with ultra-soft stretchable fabric for a comfortable fit. Shield Pro undershirts are treated with Sparco's X-Cool treatment, which draws heat from the body surface to cool the driver. In addition to cooling the driver, the X-Cool treatment has an anti-bacterial effect. The Shield Pro is a tight compression-type fit, if you prefer a looser fit choose one size larger than you usually wear.
