The Auger’s design started with the basic elements of riding and racing in mind. Lightweight, ample venting & airflow, comfort, ergonomics, and maximum protection were the starting points. Built around one of the most well-ventilated EPS liners on the market, the Auger utilizes a Fiberglass shell construction with 20 vents that keep air flowing over and around the head at all times. The strong jaw line keeps the helmet clear from shoulder contact and neck movement while providing ample jaw and side impact protection. Utilizing the best materials on the market, the interior is also made from lightweight meshes and DRI-LEX® which is a moisture wicking material that helpS stimulate the airflow and aids drying time.
