The AGV AX-9 Helmet is an all-new design over the popular AX-8 DS EVO Helmet. It starts with the lightweight carbon, aramid and fiberglass shell and a redesigned peak for optimal aerodynamics. The peak itself is adjustable to reduce the sail effect at high speeds. Superior ventilation is achieved with 5 total vents: an adjustable chin-vent, two brow inlets and 2 extractors. The design of this helmet also allows for four different configurations -- peak / visor, no peak / visor, peak / goggles, no peak / goggles -- meaning it can handle practically any riding scenario.
On the inside, the helmet has a fit to allow for comfort while wearing glasses and the padding is treated for optimal comfort. The cheek pads and top liner are moisture wicking and the neckroll is water resistant to prevent water from getting inside the helmet.
