The Terrae provides the perfect balance of quality and value for your riding adventures. With advanced ventilation systems, rigorous impact testing, and a lightweight design, the Terrae offers more riders the same level of performance and protection found in top-of-the-line helmets.NTA 8776 certified, the MET Terrae is able to dissipate significantly more impact energy. The shell also has more impact-tested coverage around the two most sensitive brain areas: the back and the temples, resulting in a safer choice for your rides. Extremely comfortable and secure on the head, the new Terrae is designed to be stable while riding on rough terrain. Featuring the Safe-T Heta 360° retention system, the fit is micrometrical and customised to the perimeter of the head, avoiding any pressure points or discomfort on long rides.Specification:In-mould polycarbonate shell with EPS linerMIPS C2® rotational management system engineered to add protection in the event of certain impactsNTA 8776 certified
