Sparco RW-11 Seamless Nomex Shirt

The Sparco RW-11 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-11 features a fully seamless structure with ultra-soft stretchable material for a very comfortable fit. RW-11 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-11 Undershirt is a seamless design with no seams for additional comfort. The undershirt is available in three sizes: X-Small/Small, Medium/Large, X-Large/XX-Large. The RW-11 undershirt is a compression type fit, if you prefer a looser fit choose one size larger than you normally wear.

Available in black or white.
