Additional protection for high speed Gass Fluid enhances the safety features of this helmet with a 39% reduction in the force of rotational and linear impact. The Fluid Inside system includes several pods that absorb impact by simulating the behaviour of cerebrospinal fluid in the brain, thus creating an additional protective layer inside the helmet. Ideal for road races and triathlons, with instant release magnetic clasp and its aerodynamic coefficient.
