Engineered to provide maximum functionality and ease of use, the face shield incorporates a lock-down lever that doubles to provide incremental ventilation when needed. Ten distinctive ratchet positions offer a setting for every riding possibility, and the 6D articulating pivot ensures a snug fit to the shell when closed. Shield changes are easy and quick requiring no tools. A beveled top edge improves laminar flow onto the helmet's surface reducing buffeting and wind noise, while the shield's flat surface accepts accessory tear-offs (sold separately) for race applications. All shields are treated for anti-scratch inside and out, provide UV protection, and distortion free vision. Replacement faceshield for the 6D Helmets ATS-1 Helmet.
