With the N30-4, Nolan has designed a helmet for the new inner city traffic. The all-rounder comes in four versions. The jet helmet Nolan N30-4 T keeps minimalist for the city appearance. The Extreme Ventilation System ensures the best ventilation even when riding slowly. The N30-4 meets the safety standards (ECE 22-06) for motorcycles, but is as comfortable as a bicycle helmet. It is a patented double lever retention system with micrometric adjustment. It consists of a thermoplastic ergonomic opening lever, and of a second aluminium toothed and holding lever. The toothed lever releases the micrometric strip, thus the chin strap can only be open with a very broad rotation of the opening lever. This device minimizes the possibility of unintentional opening of the retention system. “Clima Comfort” inner padding The inner comfort padding is designed to offer both the typical lightness of a jet helmet and the close fit of a full-face helmet. The chin straps integrated into the liner (which are therefore removable and washable), favor the helmet’s fit as well as its wearability.
