Hybrid Sport Harness Sizing Chart

The Simpson Hybrid S is the only FIA- and SFI-approved frontal head restraint specifically designed for 3-point belt systems. Third-party FMVSS208 tested, it significantly reduces neck tension in impact events when compared to helmet-only setups. The HYSXLG11PA includes post anchors and a sliding tether system, providing a direct connection to compatible helmets. The carbon fiber shell offers strength with minimal weight, and its low-profile shape eliminates interference with seatbacks and exit zones. Built for larger drivers who require top-tier safety with post-mounted helmet compatibility.
