The simple shield design and sleek angles make the Alliant an easy choice for riders looking for single lens performance and protection. The venting on the Alliant lens promotes airflow, while the adjustable ear and nose pads of hydrophilic rubber increase grip when perspiring. The Bombproof Grilamid TR-90 nylon frame sets the stage for durability and comfort. Shatterproof and scratch resistant single lens provides near perfect optics with no distortion. The Alliant Interchange models come with a three lens pack which includes AC Red, Smoke and Clear to cover all light conditions. The Fototec version comes only with the UV light reactive shade-changing Fototec lens.
