Hybrid Sport Harness Sizing Chart

The Simpson Hybrid S is a compact, FIA- and SFI-approved head restraint built for 3-point harness use. It’s validated through FMVSS208 testing for reduced neck tension and includes a carbon fiber shell with low-profile wings to prevent interference with seatbacks or roll bars. The HYSSML11M61 ships race-ready with a sliding tether M61 anchor, and the frontal buckle design eliminates bulk under the harness. Sized for smaller drivers, it’s a solid solution for instructors, OEM testers, or competitors needing lightweight restraint performance without post anchors.
