The all-new X Light Evo-4 Ergo breaks new ground in driver comfort and racing suit design. Sparco’s engineers spent countless hours analyzing the driver’s body behind the wheel to develop an ergonomic and revolutionary suit design. A unique shoulder entry system replaces the traditional front zipper and helps eliminate uncomfortable fabric bunching while seated. This design also allows for a more comfortable, lower pre-formed collar. Large stretch panels along the shoulders, sides and back improve comfort and flexibility. The X Light Evo-4 Ergo is designed entirely from lightweight and breathable Nomex® material with an X Cool Silver inner lining that draws heat from the body surface to cool the driver. Available in gray or black in sizes from small to XX-large. The X Light Evo-4 Ergo is SFI approved.
