Hybrid Sport Harness Sizing Chart
The Simpson Hybrid S is the only FIA- and SFI-approved head restraint specifically designed for use with 3-point harness systems. Validated through FMVSS208 third-party testing, the system significantly reduces neck tension under load compared to a helmet-only setup. The HYSMED11M61 model includes a carbon fiber shell, low-profile back design for clean exits, and a front-mounted buckle system. It ships with the M61 sliding tether anchor for secure helmet connection. Ideal for track day instructors, OEM test engineers, or any driver requiring compact, FIA-compliant head restraint without post anchors.

Superior Safety Engineering In A Durable, Lightweight Design
The Hybrid Sport neck restraint harness is the next evolution of the Hybrid Pro Rage technology. Constructed from DuPont carbon polymer materials, the Hybrid Sport is in every way superior to previous neck restraint models. The sliding tether system allows for greater side to side movement. The carbon polymer construction makes the Hybrid Sport 20% lighter than previous models, and much more durable than standard polymer models. The high wing shoulders allow for secure seatbelt containment. The Hybrid Sport straps directly to the driver, allowing it to safely and securely hold your neck and helmet in place, while still allowing superior range of motion.
