Impact Racing Phenom DS 2-Layer Driver Suits blend modern, Euro styling with quality USA craftsmanship you have come to enjoy and expect. The stylish and comfortable suits feature a lightweight sateen Nomex construction that passes FIA and SFI 3.2/A standards. 360-degree arm gussets, a 180-degree belt, and ribbed arm cuffs allow you to keep focused on the track ahead, instead of trying to get comfortable in the seat!
