Arai Vector 2 Helmet - Solid The Arai Vector 2 Motorcycle Helmet is the successor to Arai's hugely popular Vector model. New features for the Vector 2 Helmet include an SAI visor similar to RX-Q and Corsair V which provides wider field of vision. A replaceable interior liner has been modified to improve air flow around the head and to provide a more comfortable fit eliminating pressure points. The ventilation system has been revamped with a larger size switch and larger rear duct which will create 50 more vacuum.. Solid Colors Frost indicates a Matte finish Diamond refers to a metallic finish with metal flake Complex Laminate Construction (CLC) shell that combines excellent shell integrity with light weight Arai's exclusive multi-density, single piece hybrid EPS liner Arai's multi-density EPS liner is like no other, comprised of up to 5 different densities in some models which is molded into a single piece The single-piece hybrid liner and its unique benefit the direct-fused contact area that each EPS call shares with its neighboring cells creates a mutual support - as one cell is crushed under impact, the surrounding cells assist with the energy absorption. (Liner pieces that are simply fitted or glued together cannot rely on such a high-level support bond.) New ACF-2 front intake vent has an oversized intake opening for better airflow, and a sliding-door mechanism to more completely close it Brow Vent Faceshield Ventilation System provides cooling air in upper face area without holes in critical forehead area of the shell or in the impact-absorbing liner material Exclusive removable 5 mm Peel - away Cheek and Temple Pad layer-provides additional level of customization and fitment Extreme peripheral view - same wider field of side to side visibility as the top-of-the-line Corsair V racing helmet (an additional 5mm on each side when compared to to previous Vector model) New tuned rear vent/wing - Air inlets provide improved interior ventilation and heat removal Hyper-Ridge band - newly sculpted lower reinforcement band provides stability and lower center of gravity for a lightweight feeling. Larger side exhaust ports to increase airflow and minimize noise Dual pivot chin vent to direct air to the rider or the shield for de-misting Reinforced shell ridges with integrated side exhaust vents Larger bottom opening for easier on and off Removable/replaceable cheek pads with 5mm peel-away layer Micro-fitting 5mm peel away cheek pad layer first introduced on the RX-Q comes standard on the Vector 2. Gives you the option of a thinner cheek pad set for a custom fit without having to purchase additional cheek pads Expanding on the 5mm peel-away cheek pads, the Arai Vector 2 is the first Arai model to offer 5mm peel away temple pads as well Interior Shape Intermediate Oval - This shape is designed for the rider whose head has a front-to-back dimension that is longer than the side-to-side dimension. This is a neutral head-shape design which tends to fit most riders well. Meets or exceeds Snell M2010 and D.O.T. standards
