3.3 Undergarments

Epicracewear 3.3 SFI undergarments are made to support drivers with added protection and all-day comfort on the track. Designed to meet SFI 3.3 standards, these base layers help provide an extra level of fire resistance while maintaining breathability and a smooth fit under racewear.

The lightweight fabric allows natural movement and helps manage heat during long sessions. Flat seams reduce irritation, making the undergarments comfortable to wear for practice days and race weekends. Each piece is shaped to sit cleanly under suits without bunching or restriction.

Epicracewear 3.3 SFI undergarments are a reliable choice for karting and motorsport drivers who value safety, comfort, and consistent performance.
