The Sparco RW-10 line of Nomex® undergarments is the lightest and most breathable on the market that is homologated to the new FIA 8856-2018 standard. When designing this new line of undergarments, Sparco studied the drivers seating position to ensure ultimate fit and comfort. The RW-10 features a fully seamless structure with ultra-soft stretchable material for a very comfortable fit. RW-10 shirts and underpants 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, X-Cool treatment has an anti-bacterial effect.
The RW-10 Compression sock is the only FIA approved compression sock on the market. It features a unique helical structure that provides a gradual Class 1 compression force. This graduate compression force uses the same principles used in action sports. The RW-10 sock exerts maximum pressure at the ankle and then decreases going upwards towards the calf, to facilitate the upward return of blood circulation.
