The Giros Nine concept was introduced over ten years ago, and at the time it revolutionised the helmet industry with excellent fit, first-class safety and low weight. The latest version is an evolution of everything learned so far and the fit is the best ever. For winter 2015/16, Nine is equipped with MIPS technology, which reduces rotational force to the brain in the event of a fall. MIPS increases safety significantly, a property that is documented and medically verified. In Form Fit System provides stepless adjustment of size and fit, also vertically. The Super Cool ventilation system provides adjustable climate control and at the front of the helmet, Stack Ventilation carries away heat and moisture from the forehead and goggles.
