The Nolan N100-5 Hilltop N-Com flip-front motorcycle helmet has an outer shell made from Lexan, a polycarbonate thermoplastic with superior impact strength used in bullet-resistant 'glass'! The N100-5 Classic shell is more compact than its predecessor, the N104, with better aerodynamics and lower weight. The Nolan N100-5 Classic N-Com is a dual homologated motorbike helmet, meaning you can ride with the helmet in either an open or closed position. The clever design ensures that the snug-fitting chin bar hugs the outer shell for less drag and wind resistance when it is in the open position. Nolan's exclusive Air-Booster technology system with two large intake vents forcing cool air into the most critical areas and two exhaust vents to dispel the warm moist air ensure optimal ventilation. Internally, the inner impact absorption EPS liner is fixed to the outer shell, improving safety and eliminating that creaking sound of modular helmets. The large viewport has a scratch-resistant visor for increased peripheral vision, an anti-fog Pinlock insert, and the internal drop-down sun visor has an automatic retraction system. The improved, larger chin curtain and adjustable neck roll keep out wind and road noise for improved comfort. The retention strap has the patented Microlock2 system, a double lever retention system with a micrometric adjustment that prevents unintentional or accidental opening of the chinstrap. This is also available in different designs and colours. Each Nolan helmet has a colour number. The Hilltop design is in colour 049, white, red and blue.
