Nives X is a helmet with hybrid construction that combines the advantages of In-Molding Technology with the ABS upper shell, for an incredibly light and at the same time impact resistant helmet. It is equipped with a passive ventilation system and has air front holes that allow the air coming from the goggle to flow out, thus preventing fogging. Finally Nives X is equipped with a 3D adjustment system that can be controlled both horizontally and vertically to ensure a precise and individual fit.
