An innovative helmet with a shell made of thermoplastic material, featuring unmatched lightness and ventilation. The shell, fitted with extensive air intakes, ensures an adequate air flow that makes this helmet extremely comfortable to use even in very hot conditions. The lightweight visor has been designed to be detachable and thereby allow the helmet to be adapted to specific conditions of use. The ear flaps, which are a standard feature, can be integrated with the helmet structure and ensure the same modular function. The washable and removable lining makes the helmet easy to clean. The helmet has been designed with an adjustment rotor that ensures a perfect fit.
