Protect yourself with advanced race-proven safety technology using the Meru Safety Ascent Head and Neck Restraint with IDS. Built from lightweight carbon fiber and certified to SFI 38.1, the Ascent Carbon is engineered to help reduce concussion-causing forces while maintaining critical neck protection. Its innovative Inertia Dampening System (IDS) uses a built-in hydraulic shock absorber and proprietary speed-sensitive valving to control helmet movement through the full length of an impact, helping reduce angular and linear acceleration forces. Meru states the system reduced force through the head on the Z axis to just under 53G in a 70G impact during testing, while remaining well under upper-neck tension thresholds. Designed for use with 5-point or 6-point harnesses, this restraint is a strong choice for racers seeking lightweight comfort and next-level safety technology.
