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. Features Certified according to UN/ECE 22-06 Microlock chin strap closure Scratch resistant short visor Top ventilation, frontal ventilation, air exhausts Removable Clima Comfort lining with eco-friendly fabric Liner with innovative mesh construction enhanced chin padding for practical use & comfort Chin protector Extreme Ventilation System (EVS) Ring to connect the helmet Water & wind resistant cap (ready for) Lexan™ thermoplastic outer shell 2 shell sizes XXS-L / XL-3XL 5 EPS sizes Microlock² (patented) Availability according to the product version. It is a patented double lever retention system with micrometric adjustment. It consists of a thermoplastic ergonomic opening lever, & of a second aluminium toothed & 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 & the close fit of a full-face helmet. The chin straps integrated into the liner (which are therefore removable & washable), favor the helmet’s fit as well as its wearability. Note Please be aware, as long as nothing else is written in the item description: All helmets will be delivered only with the ECE certification by default, even if it is shown differently. all helmets that have a visor will be delivered with a clear visor, even if it is shown differently.
